Openapi official documents

Two main services deliver official documents; both are asynchronous (request → poll → download PDF) and paid per document — check wallet credit (openapi-auth skill) and confirm with the user before bulk requests.

DocuEngine (preferred) — https://docuengine.openapi.com

Official documents from the Business Register, Revenue Agency, Municipalities and INPS, behind one uniform API:

1. GET /documents — list available document services (codes, prices).
2. POST /requests — create a request with the service code and subject (VAT/tax code); optionally pass a callback URL.
3. GET /requests/{id} — poll until the request state is fulfilled (EVASA).
4. GET /requests/{id}/documents — download the resulting documents.
5. PATCH /requests/{id} — update a request when the service asks for it (e.g. optical balance-sheet processing).
