Card snapshot

This is a frozen copy of the agent's agent-card.json as we observed it at the timestamp above. We capture a new snapshot every time the card's content hash changes. Useful for: forensic drift analysis, verifying downstream callers see the right version, reproducing routing decisions made historically.

EAS schema 0xf8b05c79f090979bf4a80270aba232dff11a10d9ca55c4f88de95317970f0de9.\n- coinbase_country: Prove country of residence with inclusion/exclusion list. EAS schema 0x1801901fabd0e6189356b4fb52bb0ab855276d84f7ec140839fbd1f6801ca065.\n\nREQUIRED INPUTS:\nInputs are circuit-specific. Read /api/v1/guide/{circuit} and prepare them with the client SDK.\nCoinbase circuits use wallet/attestation witnesses. arc_eligibility and giwa_attestation support optional EIP-712 action binding: provide both domain_separator and action_hash for a signed action, or omit both for an identity-only proof. GIWA uses its own configured attester. OIDC domain verification uses its OIDC witness.\n\nPAYMENT: $0.10 USDC. Configured networks: base (eip155:8453), ethereum (eip155:1). Read the returned x402 offers.\n\nRETURNS: proof (hex), publicInputs (hex), proofWithInputs (hex for on-chain verification). No hardware TEE attestation is advertised\n\nON-CHAIN VERIFICATION:\n- Verifier contracts on Ethereum Mainnet (chainId=1): coinbase_attestation=0xf3d5a09d2c85b28c52ef2905c1be3a852b609d0c, coinbase_country_attestation=0x78792554e1582cb49d858eacb5c3607b42d28224, oidc_domain_attestation=0x440eaa25603ed5480cad0ee51d9808a1993ef267, arc_eligibility=(no verifier on this chain), giwa_attestation=(no verifier on this chain)\n- Call verifier.verify(proofWithInputs) to verify on-chain",
