How this service works
Search the current Code of Federal Regulations - CFR citation, part and section, heading, text excerpt, effective date and link, filterable by title
Output
Returns a JSON object containing the interpreted query string, the data source, total match count, number of results returned, and an array of matching CFR sections. Each section includes the formatted citation, part number, section number, heading text, a matching text excerpt, effective start date, title number, section type, and a canonical URL to the full text on eCFR.gov.
Example use cases
Compliance research for a startup
“Can you search the federal regulations for anything related to 'money transmission' and show me the most relevant CFR sections, including their citations and where I can read the full text?”
Environmental permit requirements lookup
“Look up CFR sections about 'stormwater discharge permits' — I need the section headings, citations, and excerpts so I can figure out what federal rules apply to our construction project.”
Food labeling regulation research
“Search the Code of Federal Regulations for 'nutrition facts label' requirements and give me up to 10 matching sections with their effective dates and links.”

Endpoint
GEThttps://saylorinnovations.com/api/law/ecfr?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to search the current, live text of the Code of Federal Regulations by keyword and retrieve structured regulatory citations, excerpts, and links. Prefer it over general web search when you need structured CFR metadata (citation, part, section, effective date) rather than unstructured text, and when compliance accuracy with current regulatory text is important.
Side effects
- Empty results if query terms do not match any current CFR text
- No results for highly specific or obscure regulatory topics
- Limit parameter ignored or defaulted if outside 1-25 range
- Stale data if eCFR source has not yet reflected recent regulatory changes
- Query misinterpretation if search terms are ambiguous or too broad
