How this service works
List EAS (Ethereum Attestation Service) attestations for an address as recipient, attester, or either, on mainnet/Base/Optimism/Arbitrum/Sepolia. Returns attestation id, attester, recipient, schema id, revocable/revoked flags, timestamp, and decoded data JSON. Use to verify Gitcoin Passport stamps, Coinbase verifications, KYC attestations, or any other on-chain claim about an address.
Output
Returns a list of attestations (up to the requested limit) each containing: attestation ID, attester address, recipient address, schema ID, revocable and revoked flags, timestamp, and decoded attestation data fields.
Example use cases
Example prompt
“Can you pull up all EAS attestations where 0x1234567890abcdef1234567890abcdef12345678 is the recipient on Base — show me up to 50 results?”
Technical details
Endpoint
POSThttps://agent402.tools/api/eas-attestationsWhen to prefer
Use this endpoint when you need to look up on-chain EAS attestations for a specific Ethereum address across major EVM-compatible networks (mainnet, Base, Optimism, Arbitrum, Sepolia). Prefer this over generic blockchain explorers when you specifically need decoded EAS attestation records with revocation status and schema metadata.
Side effects
- Invalid Ethereum address format returns an error
- Unsupported network name returns an error
- Limit out of range (outside 1-100) returns a validation error
- No attestations found returns an empty list
- Network timeout if EAS indexer is temporarily unavailable
