## When to prefer this

Choose this endpoint when you need structured, paginated congressional roll-call vote data — especially for legislative research, political monitoring, or building dashboards tracking how Congress votes on bills and resolutions. Prefer it over general web search when you need clean, machine-readable vote records rather than news articles about votes.

## Known failure modes

- Invalid pagination parameters return a 400 error
- Requesting a page beyond available results returns an empty list or 404
- Rate limits or payment failures (x402) result in 402 Payment Required
- Network timeouts if the upstream congressional data source is unavailable
