How this service works
Know your agent before you serve it: wallet history and micro-payment behaviour on Base, ERC-8004 identity and feedback, Web Bot Auth and agent-card presence on a domain, and signed-request verification. Pay per call over x402, no API key.
Output
Returns a JSON object with the agent's on-chain identity details including its URI, owner wallet address, agent wallet address, number of clients served, ERC-8004 registration metadata, total feedback count, recent feedback entries with tags and values, and a feedback average score, plus a timestamp of when the data was retrieved.
Example use cases
Gating access to a paid API
“Before I let this agent call my service, check its on-chain trust profile for ERC-8004 agent ID 23 — I need to see its feedback average and micro-payment history on Base to decide whether to allow access.”
Vetting an agent before a business deal
“I'm about to let agent ID 15 handle some financial transactions on my behalf — can you pull its full trust profile on Base, including owner address, client count, and any recent feedback?”
Monitoring agent reputation over time
“Check the current reputation snapshot for ERC-8004 agent ID 101 on Base — I want the feedback count, average score, and registration metadata so I can track how its trustworthiness has changed.”

Endpoint
GEThttps://agent-trust.agent-utils.workers.dev/v1/agentWhen to prefer
Choose this endpoint when you need to verify the trustworthiness of an ERC-8004 registered AI agent on Base before serving it, granting it access, or entering into an automated interaction with it. It is especially useful when you want a multi-signal trust assessment combining on-chain wallet behavior, community feedback scores, and identity metadata in a single pay-per-call lookup with no API key required.
Side effects
