Fetch identity for Web3 agent auth
“Pull the x402 passport record for my wallet 0xDeAdBeEf0000000000000000000000000000dEaD so I can use it to authenticate with a paid agent service.”

Technical details
Endpoint
GEThttps://api.x402passport.xyz/v1/x402/passport/:wallet?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve x402 passport identity or credentials for a specific wallet address in a Web3 or agent context. It is purpose-built for the x402 protocol and suited for access control checks, identity verification, and credentialing workflows where wallet-based identity is the primary signal.
Side effects
- Wallet address not found — no passport record exists for that wallet
- Invalid wallet address format — malformed address returns 400 or validation error
- Payment failure — $0.05 USDC micropayment not fulfilled results in 402 Payment Required
- Rate limiting — too many requests from the same source
- Passport expired or revoked — wallet exists but credentials are no longer valid
