How this service works
Due diligence on an ERC-8004 agent before you pay it or call it: live services and their health, metadata completeness, onchain feedback count and score, wallet activity, concrete red flags, and a usable/caution/avoid verdict with a 0-100 score. Call it when you must decide whether another agent is safe to transact with. Params: chain (default 8453) and agent_id (ERC-8004 token id).
Output
Returns a structured report including: live service health statuses, metadata completeness rating, onchain feedback count and aggregate score, wallet activity summary, a list of concrete red flags, and a final verdict of 'usable', 'caution', or 'avoid' backed by a numeric 0-100 trust score.
Example use cases
Pre-payment agent trust check
“I'm about to send USDC to agent token ID 42 on Base chain — can you check its trust score, onchain feedback, and whether there are any red flags before I go ahead?”
Fleet vetting before orchestration
“I'm building an agent pipeline and need to vet agent token ID 15 on Base. Can you pull its full due diligence report — services health, metadata completeness, and the usable/caution/avoid verdict?”
Investigating a flagged agent
“Someone warned me about agent ID 88 on Base chain 8453 — can you check its onchain feedback score, wallet activity, and any concrete red flags so I can decide whether to blacklist it?”
Technical details
Endpoint
GEThttps://my-agent-tau.vercel.app/v1/agent-check?utm_source=zero.xyzWhen to prefer
Use this endpoint whenever an AI agent must decide at runtime whether another ERC-8004 agent is safe to pay, call, or include in a workflow — especially before any financial transaction. It aggregates live health checks, onchain reputation, and wallet signals into a single actionable verdict, making it superior to querying registry contracts or feedback contracts individually.
Side effects
- Invalid or non-existent agent_id returns an error or empty result
- Unsupported chain ID results in a bad request or default fallback
- Onchain data temporarily unavailable due to RPC issues
- Agent registry lookup timeout on congested chains
- Missing required agent_id parameter returns a 400 error
