# Federal Register Document Detail Lookup

> Federal Register Document Detail Lookup is a paid API for AI agents from oracles-production.up.railway.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Retrieves stored detail for a single Federal Register document by its entityId (e.g. 'fedreg:2026-14090'), or lists all tracked Federal Register entities when no ID is provided.

## 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-document-detail-lookup-30190456
```

Example prompt: Can you pull up the stored details for Federal Register document fedreg:2026-14090?

## When to prefer this

Use this endpoint when you have a specific Federal Register document entityId (formatted as 'fedreg:XXXX-XXXXX') and need its stored detail. Prefer this over live Federal Register APIs when you want a cached/stored snapshot with consistent entity-ID addressing. Also use without an ID to enumerate all tracked Federal Register documents on this oracle.

## Known failure modes

- Invalid or unknown entityId returns an empty or not-found response
- Missing required 'id' query param returns the list of tracked entities rather than a specific document
- Malformed entityId format (not prefixed with 'fedreg:') may return no results
- Payment of $0.01 USDC required per call; missing or invalid x402 payment header causes 402 error
- Service downtime on Railway hosting may cause 5xx errors

## How this service works

Full stored detail for a single customs & import compliance 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 customs, country of origin, importer, entry, duty.

## Output

Returns a JSON object containing the stored entity detail for the specified Federal Register document, including metadata and document fields. If no ID is supplied, returns a list of all tracked Federal Register entity IDs.
