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 script-master-labs-x402-social-search-u-s-federal-data-api-c6ec8522
```

Example prompt: Search the U.S. federal data API for 'SNAP benefits enrollment' and return up to 10 results — it costs a fraction of a cent per call and settles in USDC.

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call access to U.S. federal data using blockchain-native micropayments (USDC on Base via x402). It is ideal for agents that need to search public government records without a subscription, especially in automated pipelines where sub-cent billing per query is preferable to flat-rate plans. Prefer alternatives if you need structured schemas, reliable uptime SLAs, or non-federal data sources.

## Known failure modes

- Payment not received or x402 handshake fails — request rejected with HTTP 402
- Missing required 'q' query parameter — request rejected with validation error
- Invalid or malformed input schema — 400 Bad Request
- Service unavailable on Render.com hosting — 503 or timeout
- Empty result set returned when query matches no federal records

## How this service works

Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.

## Output

Returns a list of matching U.S. federal data records for the given search query, structured as JSON. The response schema is minimal and the exact fields depend on the underlying dataset returned, but typically includes matching entries relevant to the query term.
