How this service works
Paid public-data feeds. Unpaid requests return HTTP 402. Prices are USDC on Base.
Output
Returns a JSON array of slim Federal Register document records including document titles, types, issuing agencies, publication dates, and HTML UI links to the full documents on federalregister.gov. The response also includes source metadata and pagination info.
Example use cases
Tracking agency-specific new rules
“Pull the latest 20 Federal Register documents from the FDA published since January 1st this year so I can see what new rules or notices they've issued.”
Keyword search for regulatory topic
“Search the Federal Register for documents mentioning 'cryptocurrency' or 'digital assets' and give me the most recent 10 results.”
Monitoring Executive Orders
“Find any Executive Orders published in the Federal Register in the last 30 days — I want to see what's come out recently from the White House.”
Technical details
Endpoint
GEThttps://project-api-gamma-sable.vercel.app/paid/federalregister/documents?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic, pay-per-call access to Federal Register documents — rules, notices, and Executive Orders — with filtering by agency, keyword, and date range, and you want structured JSON output with direct links to the full documents. Prefer this over scraping federalregister.gov directly or using free-tier APIs when you need reliable, metered access payable in USDC on Base via the x402 protocol.
Side effects
- HTTP 402 returned if payment is not included or payment fails — endpoint requires $0.01 USDC on Base per call
- Empty items array if no documents match the search term or date range filters
- Invalid query parameter values (e.g. malformed dates) may return an error or empty result
- Rate limiting or upstream Federal Register API outages may cause failures
- Pagination out of range may return empty results
