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 matching evidence records from the Federal Register, a source identifier, the count of observed matches, and an Ed25519 cryptographic signature attesting to the result — all conforming to the arakel.machine-evidence.v2 schema.
Example use cases
AI compliance regulatory alerting
“Check the Federal Register for any new rules or notices about artificial intelligence or autonomous systems published since yesterday and return cryptographically signed evidence of what was observed.”
Pharmaceutical company regulatory watch
“Monitor today's Federal Register publications for anything mentioning 'Pfizer' or 'biologics approval' and give me a verifiable record of whether anything was observed.”
Crypto policy tracking for legal team
“Search the Federal Register for any new orders or proposed rules about cryptocurrency or digital assets published in the last 48 hours — I need signed machine-readable evidence I can pass to our compliance system.”

Endpoint
GEThttps://proof.arakelproof.space/v1/agent/regulatory-watch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need recurring, autonomous, machine-verifiable monitoring of U.S. Federal Register publications — especially when your workflow requires cryptographic proof (Ed25519 signature) that evidence was or was not observed. Ideal for AI compliance agents that must produce auditable regulatory evidence trails rather than just informal search results. At $0.005 USDC per call with free preflight, it is cost-effective for high-frequency polling loops.
Side effects
- Missing required 'q' query parameter returns a validation error
- Invalid date-time format for 'from' or 'to' parameters causes a 400 error
- Payment not received or expired x402 payment header causes a 402 Payment Required response
- Federal Register source temporarily unavailable may return INCONCLUSIVE result
- Query too broad may exceed response limits or return degraded results
