## When to prefer this

Use this endpoint when you have a specific Federal Register immigration document entityId and need to retrieve its full stored details. Prefer this over general web searches when you need structured, pre-processed regulatory data about a specific immigration notice or rule indexed by this oracle service.

## Known failure modes

- Invalid or unknown entityId returns empty or error response
- Malformed entityId format (not matching 'fedreg:XXXX-XXXXX') may return no result
- Document not yet tracked or ingested returns empty entity
- Payment not provided results in HTTP 402 response
- Missing required query parameter may return a listing rather than a specific document

## How this service works

Full stored detail for a single immigration & work authorization 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 immigration, nonimmigrant, visa, employment authorization, h-1b.

## Output

Returns a stored entity object containing the full detail record for the specified Federal Register immigration document, including regulatory content, metadata, and any tracked fields associated with the entityId. If no ID is provided, it may list tracked entities.
