## 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 scriptmasterlabs-acp-x402-us-government-search-api-81da1f35
```

Example prompt: Search the US government database for federal records related to 'infrastructure grants 2024' and return whatever public data you find.

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call access to US federal government data and want micro-payment settlement via USDC on Base using the x402 protocol. It is suitable for agents that need to query public government records, compliance data, or regulatory filings without a subscription. Prefer this over free government APIs when you need it integrated into an x402-compatible payment workflow.

## Known failure modes

- Missing or malformed 'properties' query parameter returns empty or error response
- Payment not settled via x402 protocol results in 402 Payment Required response
- No matching government records found returns empty results set
- Service unavailability on render.com hosting causes 503 errors
- Overly broad queries may return unfiltered or excessive results

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns US government search results matching the query, likely including document titles, agency sources, record identifiers, and relevant metadata. The exact response schema is minimal and may vary; agents should expect a JSON object with matched government records or data entries.
