Check whether a European company can receive an electronic invoice today, through which Peppol participants and formats, and which national e-invoicing mandate applies to it from which date. Give a French SIREN or SIRET, an intra-EU VAT number, a national company number with its country (BE KBO, NL KvK, IT P.IVA, DE), or a company name and country. The Peppol Directory is queried by free text AND by exact participant on every scheme plausible for the country (FR 0002, 0009, 0225 SIREN_routing, 9957; BE 0208, 9925; NL 0106, 0190, 9944; DE 0204, 9930; IT 0211, 0210, 9906...), results are merged and unrelated hits dropped; document types are mapped to stable capabilities (Peppol BIS Billing invoice and credit note, CII, Factur-X, PINT, order) with a can_receive_einvoice verdict. Identity from Sirene/RNE (France) or VIES; obligation calendar per country with its official source. Charged only if the company is found (a company found but not on Peppol is a 200, registered:false). 20 free calls/day per IP with header X-Free-Trial: 1.
