How this service works
Paid on-chain token, wallet, contract and research data over x402 on Base.
Output
Returns a JSON object containing a 'query' field set to 'escrow-commitment' and a 'commitment' field containing a 0x-prefixed cryptographic hash representing the on-chain commitment to the submitted work product text.
Example use cases
Freelance work delivery verification
“I just finished the analysis report for my client — generate an escrow commitment hash for this work product so it can be anchored on-chain before the payment is released: 'Completed tokenomics analysis covering supply schedule, vesting, and liquidity pool recommendations for ProjectX.'”
AI agent task completion proof
“My agent just finished its research task — create a cryptographic escrow commitment for this output text: 'Compiled list of top 20 DeFi protocols by TVL on Base with contract addresses and audit status' — I need the 0x commitment hash to submit to the escrow contract.”
On-chain milestone anchor for DAO
“We need to anchor a project milestone to the blockchain before the DAO releases funds — please generate an escrow commitment for this deliverable text: 'Phase 1 smart contract deployment completed, all three contracts verified on BaseScan with test coverage above 95%.'”
Technical details
Endpoint
GEThttps://coinop.publicvm.com/api/v1/escrow/commitment?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to cryptographically anchor a work product or deliverable to the Base blockchain as part of an escrow workflow — particularly when using x402 micropayment-gated APIs on Base. Prefer this over off-chain hashing solutions when the commitment must be verifiable on-chain and integrated with smart contract escrow release conditions.
Side effects
- Missing 'work' query parameter returns a validation error
- Invalid or empty work product text may produce a malformed commitment
- Payment not included or insufficient USDC (requires $0.01 via x402) results in a 402 Payment Required response
- Network issues with Base L2 may cause commitment generation to fail
- Malformed request type or method fields may return a 400 Bad Request
