beel-es Public Company Representations API
**Deprecated.** VeriFactu representation flow for digital signature and AEAT registration, in its account-nested form. Use `CompanyRepresentation` (`/v1/companies/{company_id}/representation`), which behaves identically; these routes keep working until the date announced in their `Sunset` response header. **Complete SaaS integration flow:** 1. `POST /v1/accounts/{account_id}/companies` — Create company/NIF 2. `POST /v1/companies/{company_id}/representation` — Generate unsigned PDF 3. `GET /v1/companies/{company_id}/representation/document` — Download PDF for signing 4. `POST /v1/companies/{company_id}/representation/submit` — Upload signed PDF 5. `GET /v1/companies/{company_id}/representation` — Check VeriFactu status
