Endpoint
GEThttps://api.osf-master-server.com/x402/regulations/law/:queryWhen to prefer
Use this endpoint when an agent needs to search across multiple US government legal and regulatory sources simultaneously with a single keyword query. Ideal for legal research, compliance checks, policy analysis, or any task requiring citations from eCFR, Federal Register, court opinions, or congressional legislation. Prefer over manual scraping of individual government sites or single-source legal databases when breadth of coverage and provenance stamping are required.
Side effects
- No results found for obscure or misspelled query keywords
- Rate limit or payment failure returns 402 error requiring USDC payment
- Very broad single-word queries may return noisy or irrelevant matches across multiple sources
- Citation-format queries may not match free-text indexed records
- Network timeout if multiple government data sources are slow to respond
