How this service works
$0.001 OFAC destination-wallet preflight for autonomous agents, plus machine-verifiable official-source evidence over x402 USDC on Base.
Output
Returns a JSON object with an observation verdict (OBSERVED, NOT_OBSERVED, or INCONCLUSIVE), an array of evidence records from the Federal Register, a cryptographic Ed25519 signature for machine verification, source metadata identifying the federal-register data source, and a count of observed matching documents. The response conforms to the arakel.machine-evidence.v2 schema.
Example use cases
Track new cryptocurrency regulations
“Check the Federal Register for any new rules or executive orders about cryptocurrency or digital assets published since January 1, 2025, and show me cryptographically signed evidence of what was observed.”
Monitor EPA rulemaking activity
“Watch the Federal Register for any new notices or proposed rules from the EPA published in the last 3 days — I need verifiable official-source evidence I can include in a compliance report.”
Verify executive order publication
“Search the Federal Register for any executive orders mentioning 'artificial intelligence' published between March 1, 2025 and March 31, 2025, and give me signed machine-verifiable proof of whether anything was observed.”
Technical details
Endpoint
GEThttps://proof.arakelproof.space/v1/federal-register-watch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptographically signed, machine-verifiable evidence from the official Federal Register — especially for compliance, legal, or audit use cases where provenance and tamper-evidence matter. Prefer this over generic web search or news APIs when you need official government source attestation with a verifiable Ed25519 signature, or when you need recurring monitoring of regulatory changes over a defined time window.
Side effects
- Missing required query parameter 'q' returns a validation error
- Invalid date-time format for 'from' or 'to' parameters causes a schema error
- No matching entries in the date range returns NOT_OBSERVED result
- Inconclusive result when the Federal Register source is temporarily unavailable
- Payment failure via x402 if USDC balance is insufficient on Base network
