# Federal Register Energy Efficiency Document Lookup

> Federal Register Energy Efficiency Document 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 energy efficiency document by entityId (e.g. 'fedreg:2026-14090'), or lists all tracked energy efficiency 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-energy-efficiency-document-lookup-e6d0ee45
```

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

## When to prefer this

Use this endpoint when you need to retrieve full stored details for a specific Federal Register energy efficiency document by its entityId, or when you want to enumerate all tracked energy efficiency regulatory entries. Prefer this over general web search when you need structured, machine-readable regulatory data already indexed by this oracle service.

## Known failure modes

- Entity ID not found — returns empty or 404-like response if the entityId doesn't match any stored document
- Missing or malformed entityId format — may return an error if the ID isn't in the expected 'fedreg:XXXX-XXXXX' format
- Payment failure — x402 payment of $0.01 USDC required; call fails without valid payment
- Service unavailable — upstream Railway deployment may be down

## How this service works

Full stored detail for a single appliance & equipment energy standards 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 energy conservation, energy efficiency, appliance, test procedure, eere.

## Output

Returns a stored entity object containing the full detail of the requested Federal Register energy efficiency document, including regulatory metadata and content. If no ID is provided, returns a list of all tracked energy efficiency entities.
