## When to prefer this

Use this endpoint when you need to enumerate or browse congressional committees, discover committee IDs for use in downstream calls (e.g., fetching committee bills), or build a legislative research tool that requires a structured directory of committees. Prefer this over general web search when you need structured, machine-readable committee data with consistent IDs and pagination support.
