How this service works
Autonomous paid machine utilities using x402 and Base USDC.
Output
Returns a JSON object with a 'result' field containing the GENESIS* machine-readable attestation (including SHA-256 fingerprint and HMAC-SHA256 signature if GENESIS_SIGNING_KEY is configured), a 'service' field set to 'proof_attest', and a boolean 'success' field indicating whether the attestation succeeded.
Example use cases
Document integrity proof for legal records
“I need a GENESIS* signed SHA-256 fingerprint for this document summary: 'Settlement agreement between Party A and Party B, dated 2024-07-15, amount $50,000.' Can you attest it?”
Timestamped evidence fingerprint for audit trail
“Attest this audit log entry so I have a cryptographic proof: 'User admin@example.com deleted record #4821 at 2024-06-30T14:22:00Z.'”
Content authenticity stamp for AI-generated output
“Generate a GENESIS proof attestation for this AI-generated report summary: 'Q2 2024 revenue increased 12% YoY, driven by enterprise segment growth.' I want a tamper-evident signature I can store.”
Technical details
Endpoint
POSThttps://genesis.palsus2023.workers.dev/v1/proof_attest?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-use cryptographic attestation with a GENESIS* machine-readable signature format, especially in autonomous agent workflows using x402/Base USDC micropayments. It is distinct from general-purpose hashing libraries because it combines SHA-256 fingerprinting with HMAC-GENESIS signing in a single paid API call, suitable for audit trails, evidence preservation, or content authenticity stamps in agent pipelines.
Side effects
- Missing or empty 'input' string body field — likely returns success:false or an error result
- GENESIS_SIGNING_KEY not configured server-side — HMAC signature portion may be absent or placeholder
- Invalid JSON body type — request rejected at schema validation
- Payment not authorized via x402/Base USDC — call blocked before processing
- Network or Cloudflare Worker timeout — transient failure
