How this service works
ERC-8004 Inspector agent lookup (identity + reputation) — per call
Output
Returns a structured object containing: status (found/not_found/error), agentId, network, networkLabel, identity details (owner address, agentWallet, tokenURI, metadata, x402Endpoint), a reputation object (clientCount, list of clients, summary text), and any warnings associated with the agent.
Example use cases
Pre-payment agent counterparty vetting
“Before I authorize a payment to agent 0xDEF456 on Base mainnet, can you pull its ERC-8004 identity and reputation so I can see who owns it and whether it has any warnings?”
Auditing agent fleet registrations
“I need to audit all the agents in my fleet — start by looking up the ERC-8004 identity and reputation for agent 0x789GHI on Polygon and tell me its owner, wallet, client count, and any red flags.”
Discovering agent x402 payment endpoint
“I'm trying to call another agent's x402 endpoint but I don't have its URL — can you look up agent 0xJKL012 on Optimism in the ERC-8004 registry and retrieve its x402 endpoint and token metadata?”
Technical details
Endpoint
POSThttps://contextiq.trango-compute.com/api/v1/erc8004-inspector/x402-v2When to prefer
Use this endpoint when you need to resolve the full on-chain identity and reputation of a specific ERC-8004 registered agent before engaging with it — especially before automated payments, agent-to-agent transactions, or counterparty risk assessments. Prefer this over the Agent Commerce Gate when you only need the raw identity/reputation data without the full pre-payment risk decision workflow. This is the right choice when you have an agentId and network and need to verify ownership, discover the x402 endpoint, or audit client reputation history.
Side effects
- Agent not found on the specified network — status returns 'not_found'
- Invalid or malformed agentId — likely returns error status
- Unsupported or incorrect network identifier — error response
- Agent is registered but has incomplete or missing metadata — partial identity object returned
- Network RPC connectivity issues — error status with network error message
- Reputation data unavailable for newly registered agents — empty clients array
