## 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 epa-air-quality-federal-register-document-detail-lookup-9439e2cb
```

Example prompt: Can you pull up the full stored details for the EPA air quality Federal Register document with entity ID fedreg:2026-14090?

## When to prefer this

Use this endpoint when you have a specific Federal Register document entity ID (e.g. fedreg:2026-14090) and need full stored detail for that EPA air quality document, rather than searching or listing rules by timestamp. Prefer this over the feed endpoints when you already know which document you want and need its complete record.

## Known failure modes

- Missing or invalid entityId returns an empty or error response
- Entity ID not found in the stored index returns a null entity
- Omitting the id query parameter may return a list of tracked entities rather than a specific document
- Malformed entity ID format (not matching fedreg:XXXX-XXXXX pattern) may yield no results
- Payment required error (402) if x402 payment header is not provided

## How this service works

Full stored detail for a single air quality & emissions rule by Federal Register document ID (e.g. 'fedreg:2026-14090') — title, issuing agency, rule type, effective date, and 1-10 compliance-impact score. Covers air quality, emission, clean air, ozone, particulate.

## Output

Returns the stored entity object containing full details of the specified Federal Register document in the EPA air quality domain, including rule metadata, document type, and regulatory content.
