> ARAKEL Federal Award Watch is a paid API for AI agents from proof.arakelproof.space, paid per call via x402, $0.005/call, status down (last checked 2026-10-13).

Searches USASpending.gov for newly published federal awards involving a specified recipient or organization and returns machine-verifiable, cryptographically signed evidence.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability arakel-federal-award-watch-31c440a7
```

Example prompt: Search USASpending for any new federal awards involving Lockheed Martin over the past 7 days and give me machine-signed proof of what was found.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
