## When to prefer this

Use this endpoint when you need a structured, paginated roster of US Congress members with key identifiers (IDs, chamber, party, state) — especially when cross-referencing with bill sponsorship, voting records, or committee membership data available on the same Particle Pro platform. Prefer it over scraping congressional websites when you need clean, machine-readable legislative data at low cost per call.

## Known failure modes

- Invalid or out-of-range pagination parameters return an error or empty results
- Rate limiting or payment failure (x402) prevents access
- No members returned if filters are too restrictive or session data is unavailable
- Stale data if the underlying congressional roster has not been recently updated
