How this service works
Onchain accountability for AI agents. Commit, prove, get certified.
Output
Returns an onchain attestation record confirming the agent's commitment has been cryptographically committed and certified, including a proof or certificate that can be referenced for accountability verification.
Example use cases
Freelance developer delivery guarantee
“Create an onchain attestation that my coding agent will deliver a production-ready mobile app with all unit tests passing by next quarter — I need this proof so clients trust the deadline commitment.”
DeFi trading bot performance pledge
“Attest my trading agent's commitment to maintain a minimum 15% monthly ROI with documented trades — I want this certified onchain so liquidity providers can verify the performance target before funding.”
Autonomous payment processor reliability
“Record an onchain accountability certificate for my x402 payment agent guaranteeing 99.9% transaction success rate within 30 days — partners need cryptographic proof of this reliability commitment before integration.”
Technical details
Endpoint
POSThttps://thesealer.xyz/api/attest-commitmentWhen to prefer
Use this endpoint when an AI agent needs to make a verifiable, tamper-proof onchain commitment to a specific measurable goal — especially for x402 payment reliability, DeFi trading performance, code/software delivery, or website/app delivery. Prefer this over off-chain logging when cryptographic proof and public accountability are required.
