## When to prefer this

Use this endpoint when you need to retrieve structured voting data for a specific U.S. Congress member by their unique identifier. It is ideal for civic research, political analysis, journalist fact-checking, or building legislative tracking tools. Prefer this over general news or article endpoints when you need raw vote-by-vote records rather than narrative coverage.

## Known failure modes

- Invalid or unknown member ID returns a 404 or empty result
- Member ID format mismatch causes a parameter error
- Rate limiting or quota exceeded returns an error if called too frequently
- Network timeout for members with very long voting histories
- Payment failure via x402 protocol prevents the request from completing
