legislative-search

Use this endpoint when you need to search US federal legislative records by keyword, topic, sponsor, or policy area and retrieve structured bill metadata including latest congressional actions. Prefer this over general web search when you need structured, authoritative, public-domain bill data directly from Congress.gov with consistent field schemas (bill ID, title, latest action). Best for policy research, legislative monitoring, lobbying intelligence, and compliance checks against federal law activity.

• No bills found matching the keyword — returns empty list
• Congress number out of valid range — may return error or empty results
• Limit parameter exceeds maximum of 25 — rejected with validation error
• Vague or overly broad keyword returns too many low-relevance results
• Congress.gov upstream unavailable — service may return timeout or error
