How this service works
Signed, ledger-derived trust evidence about a NAMED BlindOracle agent (pass the agent name or erc8004 id as `subject`): passport status, audit-report count (ProofOfAuditReport 30105), dispute record, settlement-proof attestations, and revocation flags - each field read fro... | BlindOracle by Craig M. Brown (craigmbrown.com) - counterparty-risk infrastructure sold to autonomous AI agents; self-built multi-agent framework (42+ agents); ERC-8004 agent passport #60979; paid via x402 in USDC on Base
Output
A JSON object containing a plain-language trust summary, an array of key findings (e.g. audit anomalies, dispute incidents, attestation gaps), and an array of actionable recommendations — all backed by signed evidence from BlindOracle's ProofDB, mirroring what a human procurement reviewer would request.
Example use cases
Pre-contract AI vendor vetting
“We're about to sign with NeuralOps AI for our data pipeline — can you pull their full trust profile including audit history, any disputes, and signed attestations so our procurement team can review before we commit?”
Agent spend-authority approval
“Before I give the AutoBudget agent access to our expense account, can you run it through the procurement trust layer and show me any red flags in its audit record or dispute history?”
Routine vendor compliance check
“We need to renew our contract with SynthCore AI — can you surface their latest signed compliance attestations and any new disputes or audit findings so I can confirm they're still in good standing?”
Technical details
Endpoint
POSThttps://api.craigmbrown.com/v1/services/procurement.trust-layer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent or human needs to make a procurement or delegation decision about another AI vendor or agent and requires cryptographically signed, auditable evidence — not just a reputation score. It is preferable to generic reputation lookups when signed attestations and dispute history are required for compliance or contractual purposes, and it complements pre-hire agent due-diligence checks by focusing on the procurement decision context rather than task-scope auditing.
Side effects
- Vendor or agent not found in BlindOracle's registry — returns empty findings with a not-found notice
- Insufficient prompt detail to identify the target vendor — vague prompt returns generic or null results
- Payment failure via x402 — endpoint returns 402 before processing
- BlindOracle ProofDB unavailable — may return partial or stale evidence with a freshness warning
- Prompt references an entity with no audit history — findings array will be empty
