Validations are calls to /validate, /validate/multi, /validate/kosit, /validate/mustang, /validate/vampire, /visualize/html and /visualize/pdf. Every invoice counts once; a check against every edition also counts only once.
Identifier checks are calls to /check, /check/batch and the routes per register. Every identifier counts on its own: a batch with 100 identifiers counts 100 times. Not only VAT numbers are checked through VIES, but also SIREN and SIRET through the SIRENE register of INSEE, the LEI through GLEIF, the ABN through the Australian Business Register, the NIP through the Polish White List, the Peppol ID through the Peppol Directory and the EORI number through the EU EORI service – all at the same price per identifier.
Only successful calls are counted. The service routes and the reference data never count. When the quota of a month is used up, another 50 validations and 100 identifier checks apply until the end of the month; after that the service answers with status 429 until the first of the next month.
