EAS attestations

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.

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/eas-attestations", {
