## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability eas-attestations-lookup-3cae7156 -d '<json body>'
```

Example prompt: Can you pull up all EAS attestations where 0x1234567890abcdef1234567890abcdef12345678 is the recipient on Base — show me up to 50 results?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
