Vaultfire DilithiumAttestor — Attest Belief
x402
Vaultfire DilithiumAttestor — Attest Belief is a paid API for AI agents from theloopbreaker.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).
Pay $0.05 USDC to prepare an unsigned on-chain transaction that attests a belief hash using Vaultfire's DilithiumAttestor contract, given a ZK proof bundle from a configured origin.

How this service works
Vaultfire DilithiumAttestor.attestBelief — pay $0.05 USDC, get unsigned tx; sign locally. beliefHash is bytes32; zkProofBundle is ABI-encoded (bytes proofData, bytes originSignature) from configured origin. See GET for full spec.
Output
An unsigned blockchain transaction (tx) ready for local signing, encoding a call to VaultfireDilithiumAttestor.attestBelief() with the provided beliefHash and zkProofBundle. The agent must sign this transaction locally before broadcasting to the network.
Example use cases
Example prompt
“Attest my belief on-chain using Vaultfire's DilithiumAttestor — my beliefHash is 0xabc123...def456 and my zkProofBundle includes the proofData and originSignature from the configured origin; give me the unsigned transaction so I can sign it locally.”
Technical details
Endpoint
POSThttps://theloopbreaker.com/api/x402/actions/attest-beliefWhen to prefer
Use this endpoint when an AI agent or user needs to record a cryptographically verified belief on-chain via the Vaultfire protocol, specifically when a ZK proof bundle from a trusted origin is available and the agent intends to sign the transaction locally rather than delegate signing. Prefer this over generic contract-write endpoints when the operation specifically targets VaultfireDilithiumAttestor.attestBelief.
Side effects
- Invalid beliefHash format (not bytes32) — likely a 400 validation error
- Malformed zkProofBundle (incorrect ABI encoding or missing proofData/originSignature) — 400 error
- Origin signature verification failure — attestation rejected
- Insufficient or missing USDC x402 payment — payment required error
- Unsupported or misconfigured origin — proof bundle rejected
- Network/chain unavailability — service error
