## How to call it through Zero

```sh
zero fetch --capability congress-bill-search-bca24120 -d '<json body>'
```

Example prompt: Search US federal bills for anything related to 'artificial intelligence regulation' and give me the sponsor, current status, and a summary of each one you find.

## When to prefer this

Use this endpoint when you need a fast, one-call lookup of US federal legislation by topic — especially in agentic workflows where you want sponsor, status, and summary without scraping Congress.gov or managing a browser session. Ideal for policy monitoring, research automation, or legislative tracking where a $0.001 per-call cost is acceptable and no account setup is desired.

## Known failure modes

- No bills found matching the keyword — returns empty results or a message indicating no matches
- Vague or overly broad keyword returns too many results or a truncated list
- Congress API unavailability causes failure or incomplete data
- Malformed prompt input results in an error response
- Payment settlement failure via x402 prevents the call from completing
