## 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 federal-register-regulatory-enforcement-document-search-6c06bc48
```

Example prompt: Can you pull up any Federal Register rules, proposed rules, or enforcement notices mentioning 'Meta Platforms' — filter to FTC actions only and return up to 15 documents?

## When to prefer this

Use this endpoint when you need to find US federal regulatory, rulemaking, or enforcement documents from the Federal Register that mention a specific business entity. Prefer this over general web search when you need structured, authoritative, public-domain government records with metadata (agency, date, type). The optional CIK and QID parameters help disambiguate common company names. Best for compliance research, due diligence, and regulatory monitoring workflows.

## Known failure modes

- No documents found for an obscure or misspelled entity name — returns empty result set
- Invalid agency slug returns an error or empty results
- Limit parameter out of bounds (below 1 or above 25) triggers a validation error
- Ambiguous entity names may return unrelated documents without CIK or QID hints
- Rate limiting or payment failure (x402) if USDC funds are insufficient

## How this service works
