How this service works
Autonomous paid machine utilities using x402 and Base USDC.
Output
A JSON object with a machine-readable signed attestation result, the service name ('signed_attestation'), and a success flag. The result field contains a GENESIS-prefixed machine-readable integrity proof and processing receipt for the submitted data.
Example use cases
Audit trail for agent actions
“My AI agent just completed a financial disbursement and I need a signed, tamper-evident receipt proving it processed this payload: 'Agent disbursed 200 USDC to wallet 0xABC on block 19882201.' Generate a machine-verifiable attestation I can store for audit.”
Data provenance for submitted documents
“I need to prove that this document content was received and processed at a specific point in time — can you create a signed integrity attestation for: 'Contract v2.3 approved by committee, hash: a3f9c812'? I need it machine-readable for downstream verification.”
Tamper-evident evidence receipt
“Generate a cryptographic evidence receipt for this string so I can prove it hasn't been altered: 'Inspection result: PASS, unit ID 77-B, inspector: J. Mora, date: 2024-05-30'. I need the receipt to be verifiable by an autonomous system later.”
Technical details
Endpoint
POSThttps://genesis.palsus2023.workers.dev/v1/signed_attestation?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, paid, machine-verifiable signed attestation or processing receipt for arbitrary data — especially in autonomous agent pipelines where provenance, tamper-evidence, or audit trails are required. It is particularly well-suited for x402/Base USDC micropayment workflows and situations where a cryptographic integrity proof must be generated programmatically without a heavy PKI infrastructure.
Side effects
- Missing or empty 'input' string returns an error or empty attestation
- Invalid JSON body structure causes a 400-level error
- Payment not received via x402/USDC causes a 402 Payment Required response
- Cloudflare Worker timeout or unavailability returns a 5xx error
- Malformed input object (wrong bodyType or method) results in schema validation failure
