Example use cases

Startup regulatory due diligence
“We're launching a fintech product — can you look up the federal regulations covering 'money transmission' so we understand what rules we'd be subject to?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/law/cfr/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to search the current, authoritative text of U.S. federal regulations (eCFR) by keyword — ideal for compliance research, legal drafting, regulatory due diligence, or answering questions about what federal rules say on a specific topic. Prefer it over general web search when you need structured regulatory results tied directly to CFR sections rather than journalistic or blog interpretations of law.
Side effects
- Missing or empty 'q' query parameter returns no results or an error
- Very broad or ambiguous search terms may return too many low-relevance results
- Highly specific or obscure regulatory topics may return zero results
- eCFR upstream data may occasionally lag behind very recent regulatory changes
- Rate-limiting or payment failure (x402) if USDC balance is insufficient
