How this service works
Resolve agent identities and scores by wallet
Output

Example use cases
Example prompt
“What is the ERC-8004 trust score and agent ID for wallet 0x4f3a...b92c on Base — I want to verify whether this agent is registered and what its trust profile looks like.”
Technical details
Endpoint
GEThttps://api.8k4protocol.com/wallet/%7Bwallet%7D/scoreWhen to prefer
Use this endpoint when you have a wallet address and need to resolve it to an agent identity or ERC-8004 trust score. Prefer this over the agent-ID-based score endpoint when the only identifier available is a wallet address, not an agent_id or canonical global ID.
Side effects
- Wallet not found — no agent registration exists for the given address
- Invalid wallet address format — malformed 0x address returns an error
- Chain not supported — wallet queried on unsupported network
- Rate limiting or payment failure — x402 micropayment not processed
- Empty result set — wallet exists on-chain but has no ERC-8004 metadata
