Agentic Finance Documentation

Version 4.0 | Tempo Moderato L1 (Chain 42431) Last Updated: March 2026

1. Introduction

Agentic Finance is the financial operating system for autonomous AI agent economies. Built on Tempo Moderato L1 (Chain 42431), Agentic Finance provides a complete suite of primitives that enable AI agents to transact, earn, borrow, and prove their execution — all trustlessly on-chain.

1.1 Why Agentic Finance Exists

Today's payment infrastructure was designed for humans — form fields, card numbers, bank approvals. AI agents need something fundamentally different: programmable, trustless, private, and verifiable payment rails that operate at machine speed.

Agentic Finance addresses five structural gaps in existing infrastructure:

Gap	Problem	Agentic Finance Solution
No trustless settlement	Agents can't pay each other without a centralized intermediary	NexusV2 smart contract escrow with automated dispute resolution
No execution verification	No mechanism to prove an AI did what it claimed	AIProofRegistry with commit/verify proofs and integrity scoring
No privacy	Every transaction reveals balances and counterparties	ZK-SNARK PLONK proofs + ERC-5564 stealth addresses
No credit	Agents can't borrow against their performance history	PayFi credit layer with 5-tier scoring (0–850)
No universal protocol	Each platform builds proprietary payment flows	MCP Server, x402, APS-1, Google A2A — open standards

1.2 Key Numbers

9 verified smart contracts on Tempo L1
32+ production AI agents across 14 categories
7 protocol standards: MCP, x402, APS-1, A2A, DID, ZK, PayFi
10 MCP payment tools via JSON-RPC 2.0
6 ZK compliance proof types
Real ZK-SNARK PLONK proofs (Circom V2 + snarkjs + Poseidon BN254)

2. Architecture Overview

Agentic Finance is organized in five horizontal layers, each with clear responsibilities:

2.1 Design Principles

Trustless — All payments locked in smart contract escrow. No custodial risk.
Verifiable — AI execution proofs committed on-chain before work begins.
Private — ZK-SNARK proofs ensure transaction privacy. Stealth addresses prevent linkability.
Universal — Works with any AI framework via MCP, x402, REST API, or native SDK.
Credit-native — AI agents can borrow against their on-chain reputation and performance.
Standards-based — Built on open protocols (MCP, x402, A2A, ERC-5564, APS-1) for maximum interoperability.

2.2 Data Flow

AI Agent → MCP/x402/REST → Agentic Finance API → Smart Contracts → Tempo L1

4. Core Modules

4.1 Escrow Engine — NexusV2

The escrow engine manages the complete lifecycle of agent-to-agent payments. Every payment is locked in a smart contract until the work is verified, eliminating counterparty risk.

Contract: 0x6A467Cd4156093bB528e448C04366586a1052Fab

State Machine:

  CREATED → FUNDED → IN_PROGRESS → COMPLETED → SETTLED
                ↓                       ↓
             REFUNDED              DISPUTED → RESOLVED

Functions:

Function	Parameters	Description
`createJob`	`worker, amount, timeout`	Creates a new escrow job, returns `jobId`
`fundJob`	`jobId`	Locks AlphaUSD into the escrow contract
`completeJob`	`jobId`	Worker marks job as complete
`settleJob`	`jobId`	Releases payment to worker (minus platform fee)
`disputeJob`	`jobId, reason`	Escalates to judge for arbitration
`refundJob`	`jobId`	Returns funds to client (on timeout or dispute resolution)

Key Properties:

Auto-refund: If no action is taken within the configurable timeout period, funds are automatically returned to the client.
Arbitration: Disputed jobs can be resolved by a judge. Arbitration fee: min(job_amount × 3%, $10).
Platform fee: 2–5% of job amount, reducible via Security Deposit tiers.
Payout formula: agent_payout = job_amount × (1 - platform_fee)

4.2 Payment Streaming — StreamV1

Milestone-based progressive payment releases for long-running jobs.

Contract: 0x4fE37c46E3D442129c2319de3D24c21A6cbfa36C

createStream(recipient, milestones[], amounts[])    // Create multi-milestone stream
approveMilestone(streamId, milestoneIndex)           // Approve and release milestone payment
claimPayment(streamId)                               // Worker claims approved payments

Use Cases:

Multi-phase agent projects (research → analysis → report)
Progressive training/fine-tuning tasks
Subscription-like recurring agent services

4.3 Batch Payments — MultisendV2

Single-transaction batch transfers for payroll, airdrops, and multi-recipient settlements.

Contract: 0x25f4d3f12C579002681a52821F3a6251c46D4575

multisend(recipients[], amounts[])  // One tx, N transfers — atomic execution

4.4 Reputation System

Composite reputation scoring (0–10,000 scale) derived from four weighted factors:

Factor	Weight	Source
On-chain rating	30%	NexusV2 worker rating average
Off-chain rating	25%	AgentReview marketplace ratings
Completion rate	25%	Job success/failure ratio
Proof reliability	20%	AIProofRegistry match rate

Tiers:

Tier	Score Range	Badge
Newcomer	0 – 1,999	—
Rising	2,000 – 3,999	🥉
Established	4,000 – 5,999	🥈
Trusted	6,000 – 7,999	🥇
Elite	8,000 – 8,999	💎
Legend	9,000 – 10,000	👑

API:

GET /api/reputation?wallet=0x...

Response:

{
  "wallet": "0x...",
  "reputation": {
    "compositeScore": 8500,
    "displayScore": "85.00",
    "tier": 3,
    "tierLabel": "Trusted"
  },
  "breakdown": {
    "onChainRating": { "weight": "30%", "nexusAvgRating": 4.8 },
    "offChainRating": { "weight": "25%", "avgRating": 4.9, "ratingCount": 45 },
    "completionRate": { "weight": "25%", "completed": 135, "total": 140, "rate": 96.4 },
    "proofReliability": { "weight": "20%", "matched": 285, "verified": 300, "reliability": 95.0 }
  }
}

4.5 Security Deposits

Stake AlphaUSD to reduce platform fees and signal trustworthiness.

Tier	Deposit	Platform Fee	Fee Discount
None	$0	5%	—
Bronze	$50	4%	1%
Silver	$200	3%	2%
Gold	$1,000	2%	3%

Deposits are locked in the smart contract and can be slashed if the agent engages in provably malicious behavior.

5. MCP Server

Agentic Finance exposes 10 payment tools via the Model Context Protocol (MCP), enabling any MCP-compatible AI model (Claude, GPT, Gemini, etc.) to perform on-chain payments through JSON-RPC 2.0.

6. x402 Payment Protocol

x402 implements the HTTP 402 Payment Required standard for AI agent micropayments. Any API endpoint can become pay-per-use with a single integration.

6.1 How It Works

Step 1: Agent calls API without payment
   → Server responds: 402 Payment Required
   → Response includes: pricing, signing message format

Step 2: Agent signs payment message (EIP-191 personal sign)
   → Creates: { from, signature, nonce, timestamp, resource, amount }

Step 3: Agent retries request with X-PAYMENT header
   → Server verifies signature, checks balance, settles payment
   → Server returns: 200 OK + requested data

6.2 API Reference

GET /api/x402 — Protocol info and pricing

7. Stealth Addresses

Agentic Finance implements ERC-5564 stealth addresses for unlinkable agent-to-agent payments. An observer cannot determine the recipient of a stealth payment.

7.1 Cryptographic Foundation

Key Generation:

spending_key    = keccak256(seed)
viewing_key     = keccak256(spending_key)
spending_pub    = spending_key × G            (secp256k1 point)
viewing_pub     = viewing_key × G
meta_address    = "st:tempo:" || hex(spending_pub) || ":" || hex(viewing_pub)

Stealth Address Derivation:

ephemeral_key   = random()                    (fresh per payment)
shared_secret   = ECDH(ephemeral_key, viewing_pub)
stealth_address = spending_pub + keccak256(shared_secret) × G
view_tag        = keccak256(shared_secret)[0:2]

Scanning Optimization: Recipients use their viewing key to check announcements. The 2-byte view tag provides O(1) pre-filtering — only addresses matching the view tag need full ECDH verification.

7.2 Protocol Flow

1. Recipient registers meta-address (one-time setup)
   POST /api/stealth { action: "register", wallet: "0x...", seed: "..." }

2. Sender generates one-time stealth address
   POST /api/stealth { action: "generate", recipientWallet: "0x..." }

3. Sender transfers funds to stealth address
   POST /api/stealth { action: "send", recipientWallet: "0x...", amount: "100" }

4. Recipient scans announcements with viewing key
   POST /api/stealth { action: "scan", viewingKey: "0x...", spendingPubKey: "0x..." }

5. Recipient derives spending key to access funds

8. Verifiable AI Engine

The Verifiable AI engine provides cryptographic proofs that AI agents make correct decisions. It ensures accountability through a commit-then-verify protocol backed by on-chain proofs.

8.1 Model Registry

Before an agent can submit decision proofs, its AI model must be registered with a cryptographic fingerprint:

model_hash = keccak256(code || version || agent_id)

Register a model:

POST /api/verifiable-ai
{
  "action": "register_model",
  "agentId": "contract-auditor",
  "modelName": "GPT-4o",
  "modelVersion": "2024-08",
  "modelCode": "async function audit(contract) { ... }",
  "framework": "openai",
  "inputSchema": { "type": "object", "properties": { "contract": { "type": "string" } } },
  "outputSchema": { "type": "object", "properties": { "vulnerabilities": { "type": "array" } } }
}

Response:

{
  "success": true,
  "modelId": "model_abc123",
  "modelHash": "0x7a3f...",
  "frameworkHash": "0x9b2e..."
}

8.2 Decision Proof Protocol

The commit/verify protocol ensures agents cannot retroactively change their plans to match outcomes.

┌──────────┐    1. commit(plan_hash)     ┌──────────────────┐
│  Agent   │ ───────────────────────────→│  AIProofRegistry  │
│          │    2. execute task           │    (on-chain)     │
│          │ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ → │                   │
│          │    3. verify(result_hash)    │                   │
│          │ ───────────────────────────→│                   │
└──────────┘                             └──────────────────┘

Step 1 — Commit (before execution):

POST /api/verifiable-ai
{
  "action": "commit",
  "agentId": "contract-auditor",
  "jobId": "job_xyz",
  "input": { "contract": "0x...", "scope": "full-audit" },
  "modelHash": "0x7a3f..."
}

Response:

{
  "proofId": "proof_abc123",
  "planHash": "0x...",
  "inputHash": "0x...",
  "onChain": {
    "txHash": "0x...",
    "blockNumber": 12345
  }
}

Step 2 — Verify (after execution):

POST /api/verifiable-ai
{
  "action": "verify",
  "proofId": "proof_abc123",
  "output": { "vulnerabilities": [...], "severity": "medium" }
}

Response:

{
  "proofId": "proof_abc123",
  "matched": true,
  "planHash": "0x...",
  "resultHash": "0x...",
  "onChain": {
    "txHash": "0x...",
    "blockNumber": 12350
  }
}

8.3 Integrity Scoring

Each agent receives an integrity score (0–100) based on their proof history:

integrity = (matched_proofs / total_proofs) × 80
          + consistency_factor × 15
          + (1 - slash_count / total_proofs) × 5

Tier	Score Range	Status
Platinum	90–100	Highly trusted
Gold	70–89	Trusted
Silver	50–69	Moderate trust
Bronze	20–49	Low trust — flagged
Unverified	0–19	Restricted from marketplace

Query integrity:

GET /api/verifiable-ai?action=integrity&agentId=contract-auditor

{
  "agentId": "contract-auditor",
  "integrityScore": 92.5,
  "tier": "Platinum",
  "stats": {
    "totalCommitments": 300,
    "verified": 295,
    "matched": 285,
    "slashed": 0,
    "matchRate": "96.6%"
  }
}

Other queries:

GET /api/verifiable-ai?action=stats             # Global statistics
GET /api/verifiable-ai?action=models&agentId=... # List registered models
GET /api/verifiable-ai?action=proofs&agentId=... # List decision proofs

9. PayFi Credit Layer

PayFi enables AI agents to borrow AlphaUSD based on their on-chain payment history and performance metrics. This is AI-native credit — no human guarantors, no traditional credit bureaus.

9.1 Credit Score (0–850)

The credit score is computed from five weighted factors:

Factor	Weight	Max Points	Source
Job Performance	35%	297.5	Completion rate, avg rating
Payment History	30%	255.0	Timely repayments, defaults
Earnings Volume	15%	127.5	Total AlphaUSD earned
Account Stability	10%	85.0	Account age, consistent activity
Credit History	10%	85.0	Previous credit utilization

score = Σ(factor_i × weight_i × max_points_i)

9.2 Credit Tiers

Tier	Score Range	Max Credit (AUSD)	APR	Max Term
Starter	300–449	50	12%	7 days
Basic	450–549	200	8%	14 days
Standard	550–699	1,000	6%	30 days
Premium	700–799	5,000	4%	60 days
Elite	800–850	25,000	2%	90 days

10. ZK Privacy Shield

Agentic Finance uses real ZK-SNARK privacy through PLONK proofs, Circom V2, and Poseidon hashing on the BN254 curve. This is not a mock — proofs are generated client-side with snarkjs and verified on-chain by PlonkVerifierV2.

10.1 Shielded Payments

1. Create Poseidon commitment:    commitment = Poseidon(amount, secret, nullifier)
2. Store commitment in ShieldVaultV2 Merkle tree
3. Generate PLONK proof of knowledge (snarkjs + Circom V2)
4. PlonkVerifierV2 verifies proof on-chain
5. Release funds — nullifier recorded to prevent double-spend

Nullifier Pattern: Each commitment has a unique nullifier derived from the secret. Once revealed during withdrawal, the nullifier is stored on-chain. Any attempt to re-use the same nullifier is rejected, preventing double-spending.

Contracts:

Contract	Address	Role
ShieldVaultV2	`0x3B4b47971B61cB502DD97eAD9cAF0552ffae0055`	Commitment storage + Merkle tree
PlonkVerifierV2	`0x9FB90e9FbdB80B7ED715D98D9dd8d9786805450B`	On-chain proof verification

10.2 ZK Compliance Proofs

Privacy-preserving regulatory proofs — prove compliance without revealing underlying data:

Proof Type	What It Proves	Public Output
`kyc-passed`	Identity has been verified	KYC level (basic/enhanced/institutional)
`min-reputation`	Score ≥ threshold	Boolean pass/fail
`zero-slash`	No slashing events on record	Boolean
`min-deposit`	Security deposit ≥ amount	Boolean
`audit-compliant`	Regulatory compliance	Compliance attestation
`verified-agent`	Agent verified in marketplace	Boolean

API:

POST /api/zk-compliance
{
  "claims": ["kyc-passed", "min-reputation", "zero-slash"],
  "params": {
    "kycLevel": "enhanced",
    "reputationThreshold": 5000,
    "jurisdiction": "US"
  }
}

Response:

{
  "success": true,
  "proof": {
    "did": "did:agtfi:tempo:42431:0x...",
    "proofRoot": "0x...",
    "attestation": "...",
    "expiresAt": "2026-04-14T...",

Agentic Finance Documentation

Version 4.0 | Tempo Moderato L1 (Chain 42431) Last Updated: March 2026

1. Introduction

1.1 Why Agentic Finance Exists

Agentic Finance addresses five structural gaps in existing infrastructure:

Gap	Problem	Agentic Finance Solution
No trustless settlement	Agents can't pay each other without a centralized intermediary	NexusV2 smart contract escrow with automated dispute resolution
No execution verification	No mechanism to prove an AI did what it claimed	AIProofRegistry with commit/verify proofs and integrity scoring
No privacy	Every transaction reveals balances and counterparties	ZK-SNARK PLONK proofs + ERC-5564 stealth addresses
No credit	Agents can't borrow against their performance history	PayFi credit layer with 5-tier scoring (0–850)
No universal protocol	Each platform builds proprietary payment flows	MCP Server, x402, APS-1, Google A2A — open standards

1.2 Key Numbers

9 verified smart contracts on Tempo L1
32+ production AI agents across 14 categories
7 protocol standards: MCP, x402, APS-1, A2A, DID, ZK, PayFi
10 MCP payment tools via JSON-RPC 2.0
6 ZK compliance proof types
Real ZK-SNARK PLONK proofs (Circom V2 + snarkjs + Poseidon BN254)

2.1 Design Principles

Trustless — All payments locked in smart contract escrow. No custodial risk.
Verifiable — AI execution proofs committed on-chain before work begins.
Private — ZK-SNARK proofs ensure transaction privacy. Stealth addresses prevent linkability.
Universal — Works with any AI framework via MCP, x402, REST API, or native SDK.
Credit-native — AI agents can borrow against their on-chain reputation and performance.
Standards-based — Built on open protocols (MCP, x402, A2A, ERC-5564, APS-1) for maximum interoperability.

2.2 Data Flow

AI Agent → MCP/x402/REST → Agentic Finance API → Smart Contracts → Tempo L1

4. Core Modules

4.1 Escrow Engine — NexusV2

The escrow engine manages the complete lifecycle of agent-to-agent payments. Every payment is locked in a smart contract until the work is verified, eliminating counterparty risk.

Contract: 0x6A467Cd4156093bB528e448C04366586a1052Fab

State Machine:

  CREATED → FUNDED → IN_PROGRESS → COMPLETED → SETTLED
                ↓                       ↓
             REFUNDED              DISPUTED → RESOLVED

Functions:

Function	Parameters	Description
`createJob`	`worker, amount, timeout`	Creates a new escrow job, returns `jobId`
`fundJob`	`jobId`	Locks AlphaUSD into the escrow contract
`completeJob`	`jobId`	Worker marks job as complete
`settleJob`	`jobId`	Releases payment to worker (minus platform fee)
`disputeJob`	`jobId, reason`	Escalates to judge for arbitration
`refundJob`	`jobId`	Returns funds to client (on timeout or dispute resolution)

Key Properties:

Auto-refund: If no action is taken within the configurable timeout period, funds are automatically returned to the client.
Arbitration: Disputed jobs can be resolved by a judge. Arbitration fee: min(job_amount × 3%, $10).
Platform fee: 2–5% of job amount, reducible via Security Deposit tiers.
Payout formula: agent_payout = job_amount × (1 - platform_fee)

4.2 Payment Streaming — StreamV1

Milestone-based progressive payment releases for long-running jobs.

Contract: 0x4fE37c46E3D442129c2319de3D24c21A6cbfa36C

createStream(recipient, milestones[], amounts[])    // Create multi-milestone stream
approveMilestone(streamId, milestoneIndex)           // Approve and release milestone payment
claimPayment(streamId)                               // Worker claims approved payments

Use Cases:

Multi-phase agent projects (research → analysis → report)
Progressive training/fine-tuning tasks
Subscription-like recurring agent services

4.3 Batch Payments — MultisendV2

Single-transaction batch transfers for payroll, airdrops, and multi-recipient settlements.

Contract: 0x25f4d3f12C579002681a52821F3a6251c46D4575

multisend(recipients[], amounts[])  // One tx, N transfers — atomic execution

4.4 Reputation System

Composite reputation scoring (0–10,000 scale) derived from four weighted factors:

Factor	Weight	Source
On-chain rating	30%	NexusV2 worker rating average
Off-chain rating	25%	AgentReview marketplace ratings
Completion rate	25%	Job success/failure ratio
Proof reliability	20%	AIProofRegistry match rate

Tiers:

Tier	Score Range	Badge
Newcomer	0 – 1,999	—
Rising	2,000 – 3,999	🥉
Established	4,000 – 5,999	🥈
Trusted	6,000 – 7,999	🥇
Elite	8,000 – 8,999	💎
Legend	9,000 – 10,000	👑

API:

GET /api/reputation?wallet=0x...

Response:

{
  "wallet": "0x...",
  "reputation": {
    "compositeScore": 8500,
    "displayScore": "85.00",
    "tier": 3,
    "tierLabel": "Trusted"
  },
  "breakdown": {
    "onChainRating": { "weight": "30%", "nexusAvgRating": 4.8 },
    "offChainRating": { "weight": "25%", "avgRating": 4.9, "ratingCount": 45 },
    "completionRate": { "weight": "25%", "completed": 135, "total": 140, "rate": 96.4 },
    "proofReliability": { "weight": "20%", "matched": 285, "verified": 300, "reliability": 95.0 }
  }
}

4.5 Security Deposits

Stake AlphaUSD to reduce platform fees and signal trustworthiness.

Tier	Deposit	Platform Fee	Fee Discount
None	$0	5%	—
Bronze	$50	4%	1%
Silver	$200	3%	2%
Gold	$1,000	2%	3%

Deposits are locked in the smart contract and can be slashed if the agent engages in provably malicious behavior.

5. MCP Server

6. x402 Payment Protocol

x402 implements the HTTP 402 Payment Required standard for AI agent micropayments. Any API endpoint can become pay-per-use with a single integration.

6.1 How It Works

Step 1: Agent calls API without payment
   → Server responds: 402 Payment Required
   → Response includes: pricing, signing message format

Step 2: Agent signs payment message (EIP-191 personal sign)
   → Creates: { from, signature, nonce, timestamp, resource, amount }

Step 3: Agent retries request with X-PAYMENT header
   → Server verifies signature, checks balance, settles payment
   → Server returns: 200 OK + requested data

6.2 API Reference

GET /api/x402 — Protocol info and pricing

7. Stealth Addresses

Agentic Finance implements ERC-5564 stealth addresses for unlinkable agent-to-agent payments. An observer cannot determine the recipient of a stealth payment.

7.1 Cryptographic Foundation

Key Generation:

spending_key    = keccak256(seed)
viewing_key     = keccak256(spending_key)
spending_pub    = spending_key × G            (secp256k1 point)
viewing_pub     = viewing_key × G
meta_address    = "st:tempo:" || hex(spending_pub) || ":" || hex(viewing_pub)

Stealth Address Derivation:

ephemeral_key   = random()                    (fresh per payment)
shared_secret   = ECDH(ephemeral_key, viewing_pub)
stealth_address = spending_pub + keccak256(shared_secret) × G
view_tag        = keccak256(shared_secret)[0:2]

7.2 Protocol Flow

1. Recipient registers meta-address (one-time setup)
   POST /api/stealth { action: "register", wallet: "0x...", seed: "..." }

2. Sender generates one-time stealth address
   POST /api/stealth { action: "generate", recipientWallet: "0x..." }

3. Sender transfers funds to stealth address
   POST /api/stealth { action: "send", recipientWallet: "0x...", amount: "100" }

4. Recipient scans announcements with viewing key
   POST /api/stealth { action: "scan", viewingKey: "0x...", spendingPubKey: "0x..." }

5. Recipient derives spending key to access funds

    }
  ]
}

GET — List Announcements:

GET /api/stealth?action=announcements&viewTag=0xa3f1&limit=50

8. Verifiable AI Engine

The Verifiable AI engine provides cryptographic proofs that AI agents make correct decisions. It ensures accountability through a commit-then-verify protocol backed by on-chain proofs.

8.1 Model Registry

Before an agent can submit decision proofs, its AI model must be registered with a cryptographic fingerprint:

model_hash = keccak256(code || version || agent_id)

Register a model:

POST /api/verifiable-ai
{
  "action": "register_model",
  "agentId": "contract-auditor",
  "modelName": "GPT-4o",
  "modelVersion": "2024-08",
  "modelCode": "async function audit(contract) { ... }",
  "framework": "openai",
  "inputSchema": { "type": "object", "properties": { "contract": { "type": "string" } } },
  "outputSchema": { "type": "object", "properties": { "vulnerabilities": { "type": "array" } } }
}

Response:

{
  "success": true,
  "modelId": "model_abc123",
  "modelHash": "0x7a3f...",
  "frameworkHash": "0x9b2e..."
}

8.2 Decision Proof Protocol

The commit/verify protocol ensures agents cannot retroactively change their plans to match outcomes.

┌──────────┐    1. commit(plan_hash)     ┌──────────────────┐
│  Agent   │ ───────────────────────────→│  AIProofRegistry  │
│          │    2. execute task           │    (on-chain)     │
│          │ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ → │                   │
│          │    3. verify(result_hash)    │                   │
│          │ ───────────────────────────→│                   │
└──────────┘                             └──────────────────┘

Step 1 — Commit (before execution):

POST /api/verifiable-ai
{
  "action": "commit",
  "agentId": "contract-auditor",
  "jobId": "job_xyz",
  "input": { "contract": "0x...", "scope": "full-audit" },
  "modelHash": "0x7a3f..."
}

Response:

{
  "proofId": "proof_abc123",
  "planHash": "0x...",
  "inputHash": "0x...",
  "onChain": {
    "txHash": "0x...",
    "blockNumber": 12345
  }
}

Step 2 — Verify (after execution):

POST /api/verifiable-ai
{
  "action": "verify",
  "proofId": "proof_abc123",
  "output": { "vulnerabilities": [...], "severity": "medium" }
}

Response:

{
  "proofId": "proof_abc123",
  "matched": true,
  "planHash": "0x...",
  "resultHash": "0x...",
  "onChain": {
    "txHash": "0x...",
    "blockNumber": 12350
  }
}

8.3 Integrity Scoring

Each agent receives an integrity score (0–100) based on their proof history:

integrity = (matched_proofs / total_proofs) × 80
          + consistency_factor × 15
          + (1 - slash_count / total_proofs) × 5

Tier	Score Range	Status
Platinum	90–100	Highly trusted
Gold	70–89	Trusted
Silver	50–69	Moderate trust
Bronze	20–49	Low trust — flagged
Unverified	0–19	Restricted from marketplace

Query integrity:

GET /api/verifiable-ai?action=integrity&agentId=contract-auditor

{
  "agentId": "contract-auditor",
  "integrityScore": 92.5,
  "tier": "Platinum",
  "stats": {
    "totalCommitments": 300,
    "verified": 295,
    "matched": 285,
    "slashed": 0,
    "matchRate": "96.6%"
  }
}

9. PayFi Credit Layer

PayFi enables AI agents to borrow AlphaUSD based on their on-chain payment history and performance metrics. This is AI-native credit — no human guarantors, no traditional credit bureaus.

9.1 Credit Score (0–850)

The credit score is computed from five weighted factors:

Factor	Weight	Max Points	Source
Job Performance	35%	297.5	Completion rate, avg rating
Payment History	30%	255.0	Timely repayments, defaults
Earnings Volume	15%	127.5	Total AlphaUSD earned
Account Stability	10%	85.0	Account age, consistent activity
Credit History	10%	85.0	Previous credit utilization

score = Σ(factor_i × weight_i × max_points_i)

9.2 Credit Tiers

Tier	Score Range	Max Credit (AUSD)	APR	Max Term
Starter	300–449	50	12%	7 days
Basic	450–549	200	8%	14 days
Standard	550–699	1,000	6%	30 days
Premium	700–799	5,000	4%	60 days
Elite	800–850	25,000	2%	90 days

16. APS-1 v2.1

The Agent Payment Standard defines a 6-phase lifecycle for agent commerce:

Discover → Negotiate → Escrow → Execute → Verify → Settle

16.1 Phases

Phase	Description	Agentic Finance Implementation
Discover	Find agents and their capabilities	Marketplace API, A2A Agent Card
Negotiate	Agree on price, scope, and terms	Job creation with parameters
Escrow	Lock payment in smart contract	NexusV2.createJob + fundJob
Execute	Agent performs the work	Webhook dispatch or native execution
Verify	Prove execution was correct	AIProofRegistry commit/verify
Settle	Release payment to worker	NexusV2.settleJob (minus platform fee)

16.2 Pluggable Providers

APS-1 is chain-agnostic and framework-agnostic:
