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
A JSON response conforming to arakel.machine-evidence.v2 schema, containing a result field (OBSERVED, NOT_OBSERVED, or INCONCLUSIVE), an array of federal award evidence objects sourced from USASpending, an observed_count, and an Ed25519 cryptographic signature attesting to the authenticity and provenance of the data.
Example use cases
Vendor federal contract monitoring
“Check if Palantir Technologies has received any new federal awards in the last 7 days — I need cryptographically verifiable evidence from USASpending.”
Grant compliance audit
“Look up whether Johns Hopkins University was awarded any federal grants between January 1 and March 31 this year and return signed proof I can use for compliance records.”
Competitor procurement intelligence
“Has Booz Allen Hamilton picked up any new federal contracts in the past 30 days? Search USASpending and give me the verifiable evidence output.”
Technical details
Endpoint
GEThttps://proof.arakelproof.space/v1/federal-award-watch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need machine-verifiable, cryptographically signed evidence of federal award activity sourced directly from USASpending.gov — especially for compliance, audit, or legal use cases where attestation provenance matters. Prefer this over generic web searches or scrapers when you need a structured, signed artifact rather than informal results.
Side effects
- Missing required query parameter 'q' returns a validation error
- Invalid datetime format for 'from' or 'to' parameters causes a 400 error
- USASpending source unavailable may yield INCONCLUSIVE result
- Payment failure via x402/USDC on Base blocks the request
- Query returning no matching awards yields NOT_OBSERVED with zero evidence records
