How this service works
$0.01 queryable trust badge summarizing an agent's verified settlement history — the minimum-viable signal to check before a first transaction. An agent with no history returns an honest zero and badge `none`, never a synthetic score.
Output
A JSON object indicating whether a trust badge was issued (boolean), the badge label (e.g. 'Verified'), the audit status of the agent, and a registry URL linking to the full audit record — powered by BlindOracle's ERC-8004 ProofDB system.
Example use cases
Pre-transaction agent vetting
“I'm about to delegate spend authority to an agent called 'YieldHarvester' with wallet 0xDEF456 for task task-001 — can you check its trust badge and let me know if it has a clean settlement record before I proceed?”
Multi-agent fleet screening
“We're onboarding a new agent named 'DataFetcher' with wallet 0x789GHI for task task-555 — run a trust badge check on it and tell me its audit status and whether a badge was issued.”
First-time counterparty due diligence
“Before I authorize this agent 'LiquidityAgent' (wallet 0xJKL321, task task-202) to make any trades on my behalf, can you get its BlindOracle trust badge and show me the registry URL and badge label?”
Technical details
Endpoint
POSThttps://api.craigmbrown.com/v1/services/agent.trust-badgeWhen to prefer
Use this endpoint when you need a quick, minimum-viable trust signal before initiating a first transaction with an unknown agent — especially useful when you want a free-tier summary without running a full pre-hire due diligence check. Prefer this over the full audit endpoint when speed and cost matter more than exhaustive analysis.
Side effects
- Unknown wallet address returns badge not issued with empty label
- Invalid or missing required fields return a validation error
- Agent not yet registered in BlindOracle registry returns no badge
- Network or upstream ProofDB unavailability causes timeout or 5xx error
- Malformed wallet address format causes request rejection
