## 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 regulatory-legal-documents-lookup-x402helper-xyz-8887bb0c
```

Example prompt: Can you search for regulatory and legal documents filed against Acme Corp — check the FTC using agency slug 'federal-trade-commission' and return up to 15 documents?

## When to prefer this

Use this endpoint when you need to retrieve regulatory or legal documents from US federal agencies for a specific business entity, especially when you have a SEC CIK or Wikidata QID to narrow results. Prefer this over general web search when structured, agency-sourced compliance data is required for due diligence, legal research, or regulatory monitoring.

## Known failure modes

- No documents found for the given entity name or identifiers — result may be empty
- Invalid agency slug returns no results or an error
- CIK or QID not recognized leads to empty result set
- Limit parameter out of range (must be 1–25) causes validation error
- Payment of 0.026 USDC via x402 protocol required; unpaid requests receive 402 response

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

Returns a JSON object with a success flag and a result object containing matching regulatory legal documents from US government agencies, including document metadata such as filing details, agency source, and entity identifiers.
