# 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 2026-09-15).

Retrieves stored detail for a single Federal Register document by entityId (e.g. 'fedreg:2026-14090'), or lists all tracked 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-3187b11a
```

Example prompt: Pull up the stored details for Federal Register document fedreg:2026-14090 from the oracle — I want to see the full entity record for that entry.

## When to prefer this

Use this endpoint when you need the full stored detail for a specific Federal Register document and already know its entityId (fedreg:YYYY-NNNNN). Prefer this over a general web search when you want structured, pre-fetched oracle data about a federal regulatory document, particularly in the Medicare/reg-medicare domain.

## Known failure modes

- Unknown or untracked entityId returns empty or 404 response
- Malformed entityId format (not 'fedreg:YYYY-NNNNN') may return an error
- Payment of $0.01 USDC required via x402 protocol; missing payment results in 402 error
- Service unavailable if Railway deployment is down

## How this service works

Full stored detail for a single Medicare & Medicaid payment and coverage 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 medicare, medicaid, payment, coverage, reimbursement.

## Output

Returns a JSON object with the entity field containing the stored detail for the requested Federal Register document, including all metadata captured by the oracle for that document. If no ID is provided, returns a list of all tracked Federal Register entities.
