## 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 sitecheck-congress-bill-search-88e04681
```

Example prompt: Search Congress for bills related to 'artificial intelligence' in the 119th Congress and show me up to 5 results with their sponsors and current status.

## When to prefer this

Use this endpoint when you need fast, pay-per-call access to US Congressional bill data without an API key or signup — ideal for agents that need to look up specific bills by ID or search titles by keyword within the current or recent Congresses. Prefer this over direct Congress.gov API calls when you need x402 micropayment integration with no authentication overhead.

## Known failure modes

- Keyword search only covers the 250 most recently updated bills — older or less-active bills may not appear
- No full-text search supported — query words must appear in the bill title only
- Invalid bill ID format returns an error or empty result
- Congress number out of range (below 93 or above current) may return an error
- Limit parameter outside 1-25 range may be rejected or clamped

## How this service works

US federal bills from Congress.gov (Library of Congress). Keyword search (q) runs over the 250 most recently updated bills of a Congress, since the API has no full-text search; each match gets its sponsor, status and latest action. A bill number (bill=hr1234-119) returns its cosponsor count, committees and up to 30 actions. Public domain.

## Output

Returns a JSON object with the search query metadata, total matching bills found, a list of bill results (each with bill number, title, Congress.gov link, status, sponsor name/party/state, cosponsor count, introduction date, policy area, and latest legislative action), plus how many bills were scanned and a timestamp.
