How this service works
US federal regulations from the eCFR (Code of Federal Regulations, not statutes; not an official legal edition): search by title, or fetch one section by its id, with title, status, dates and the official link. Uncached: 404, not charged, fetched within about a minute.
Output
Returns a JSON object with the country code, section ID, regulation title, type (e.g. Section), found/ok status, source name (eCFR), source class, license details with attribution and URL, and a link to the official eCFR page. Returns 404 (not charged) if the section is not found; data is fetched live (uncached) within approximately one minute.
Example use cases
Compliance check for government contractors
“I need to look up the federal acquisition regulations in CFR Title 48 around privacy training requirements — can you pull the exact section text and tell me when it was last updated?”
Legal research on environmental rules
“Search the Code of Federal Regulations for sections related to clean water discharge standards — I'm trying to find the relevant CFR titles and sections covering EPA effluent limits.”
HR policy alignment with federal rules
“Can you find the federal regulations in the CFR that govern workplace discrimination protections? I need the section ID, title, and official eCFR link so I can reference them in our employee handbook.”

Endpoint
GEThttps://api.maxwellinternational.ai/v1/gov/us/legislation?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to look up or search US federal regulations from the eCFR by CFR title or section ID. It is ideal for compliance, legal research, or policy work requiring official regulatory text with source attribution. Prefer it over general web search when you need structured, machine-readable regulation metadata with official eCFR links. Note: this covers regulations (CFR), not statutes (US Code), and is not an official legal edition.
Side effects
- 404 Not Found – section ID does not exist in eCFR (not charged)
- Invalid title or section format causing no match
- Network timeout if eCFR API is slow (live fetch, ~1 min)
- Empty search results if query terms match no regulations
- Rate limiting or payment failure via x402 protocol
