```sh
zero fetch --capability particle-pro-list-congressional-bills-724b0ec3
```

## When to prefer this

Choose this endpoint when you need structured, paginated access to congressional bill data from a reliable API with per-call micropayment pricing. It is ideal for agents that need to enumerate, monitor, or analyze US legislative activity without managing a full legislative database. Prefer it over scraping official government sites when you need clean, structured data.

## Known failure modes

- Invalid pagination parameters return an error response
- Expired or missing x402 payment header results in a 402 Payment Required error
- Rate limiting if too many requests are made in succession
- Empty result set if no bills match the requested filters or session
- Network timeout for slow upstream legislative data sources
