How this service works
Verified cyber-physical AI tools for autonomous agents. Pay per call via x402 (USDC on Base). 26 tools covering MRV verification, biodiversity, skip twin, site certification, agent trust, transaction evidence, protocol bridging, GEO audit, IATP reputation, ABV maturity, NIST TEVV alignment, and encrypted memory write/read/query/grant/revoke/tool_context/pricing_hint/subscription_quote/attest/verify_attestation.
Output
Returns a JSON object with a boolean verified field, a numeric trust_score, the transaction_id echoed back, and payment metadata. Indicates whether the M2M transaction evidence checks out and how much trust is associated with the agent's activity.
Example use cases
Audit agent payment after M2M settlement
“I need to verify that the transaction tx_settle_42 from agent did:innovalyxx:agent_supplier_7 was properly settled — can you check the evidence and give me a trust score?”
Validate USDC payment claim from counterparty
“An agent is claiming it paid 25 USDC in transaction tx_pay_888 under DID did:web:buyer-agent.example.com — can you run the transaction evidence check to confirm it's legit?”
Pre-authorization trust check before service delivery
“Before I release the data to did:key:z6Mkabcdef123, I want to verify their transaction evidence for tx_prepay_001 and make sure the trust score is acceptable — can you do that?”
Technical details
Endpoint
POSThttps://edge.innovalyxx.com/mcp/tools/verify_transaction_evidenceWhen to prefer
Choose this endpoint when you need to cryptographically or ledger-confirm that a specific M2M USDC transaction was settled and assess the trustworthiness of the agent involved. It is purpose-built for autonomous agent ecosystems using DID-based identity and x402 micropayments, making it the right choice over generic blockchain explorers when you also need a trust score tied to the agent's DID. Prefer it in agentic pipelines that require evidence-based authorization before delivering services or data.
Side effects
- Unknown or unresolvable agent_did returns unverified result with trust_score of 0
- Non-existent transaction_id returns verified: false with no evidence found
- Amount mismatch between claimed amount_usdc and settled amount may lower trust_score or return unverified
- Missing required fields (agent_did or transaction_id) returns a 400-level error
- Payment failure via x402 (insufficient USDC balance) blocks the call entirely
- Network or upstream ledger unavailability returns a 5xx error
