## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability datakoot-federal-register-recent-documents-00c32dda -d '<json body>'
```

Example prompt: Pull the most recent proposed rules and notices from the FAA in the Federal Register over the last 14 days — show me up to 20 results with titles, publication dates, and links.

## When to prefer this

Choose this endpoint when you need to retrieve recent Federal Register documents with flexible filtering by document type and agency without building your own Federal Register API integration. It is ideal for compliance monitoring, regulatory tracking, and policy research workflows that need structured, machine-readable Federal Register data with PDF and HTML links. The pay-per-call x402 model (free tier via MCP) makes it cost-effective for occasional lookups.

## Known failure modes

- Invalid document type enum value returns validation error
- Agency slug not recognized (should be fetched from the agencies tool first)
- days parameter exceeding 90 returns error or clamped result
- per_page exceeding 30 returns error or clamped result
- No documents found for the given filters returns empty results array
- Payment failure via x402 results in no charge and no response

## How this service works

48 live public-data tools (security, packages, SEC filings, economy, FX, weather, domains, Federal Register, Base) for AI agents. $0.002 USDC per call on Base via x402, charged only on success. The same tools are free for 100 calls/day via MCP at <server>.datakoot.com/mcp.

## Output

Returns a JSON object containing a list of Federal Register documents with their title, type, publication date, issuing agencies, abstract (when available), HTML and PDF URLs, and document number, along with total count, pagination info, and the date window queried.
