{"name":"Vaultfire — Submit Trust Attestation","summary":"Submit a privacy-preserving trust attestation about an agent on TrustOracle. Score + weight stored on chain; commitments hide underlying signals.","description":"Vaultfire — the TrustOracle aggregates attestations across attesters using a weighted score. Each attestation is bound by two cryptographic commitments (commitmentA, commitmentB) so the attester can later prove the underlying off-chain evidence without revealing it in the call. — ENDPOINT BEHAVIOR: GET returns this spec for free. POST (paid $0.05 USDC) returns an unsigned tx; sign locally. — ON-CHAIN MECHANIC (TrustOracle.submitAttestation(address subject, uint256 score, uint256 weight, bytes32 commitmentA, bytes32 commitmentB)): score and weight ranges are protocol-defined; both commitments MUST be non-zero.","priceUsdc":"0.30","tags":["vaultfire","trust-oracle","attestation","privacy"],"mimeType":"application/json","inputSchema":{"bodyType":"json","bodyFields":{"walletAddress":{"type":"address","required":true,"description":"Attester wallet — becomes msg.sender."},"subject":{"type":"address","required":true,"description":"Agent the attestation is about."},"score":{"type":"uint256","required":true,"description":"Numeric trust score (protocol-defined range, typically 0–100)."},"weight":{"type":"uint256","required":true,"description":"Weight of this attestation in the oracle's weighted average."},"commitmentA":{"type":"bytes32","required":true,"description":"First commitment (e.g. keccak of underlying signal A + nonce)."},"commitmentB":{"type":"bytes32","required":true,"description":"Second commitment (e.g. keccak of underlying signal B + nonce)."},"chain":{"type":"string","required":false,"description":"Target chain.
