Extract the full contents of one electronic invoice file (Factur-X, ZUGFeRD, XRechnung, UBL or CII) as plain text: invoice number and dates, supplier and customer, every line, the VAT breakdown per rate, totals, IBAN, the EN 16931 consistency check, and whether the amounts on a Factur-X PDF's visible page match its embedded XML. Use it when the user wants to know what an invoice contains. If they only ask whether the invoice is correct, use check_invoice instead, which returns the verdict without the contents. Side effects: the file is uploaded over HTTPS to the Facturolia API, processed in memory and discarded; nothing is written locally. Requires FACTUROLIA_API_KEY; files over 10 MB are refused; requests are rate limited per key tier and a 429 error means wait and retry.

Validate one electronic invoice file (Factur-X, ZUGFeRD, XRechnung, UBL or CII) against the EN 16931 standard and return only the verdict and the list of anomalies: totals that do not add up, VAT miscalculated for a rate, missing required fields, each with the rule code and the figures involved. Use it to answer 'is this invoice correct?' or to screen several files quickly. It does not list the invoice contents; for parties, lines and totals use read_invoice. This is a consistency check, not a legal compliance certificate, and it does not transmit the invoice to any tax platform. Side effects: the file is uploaded over HTTPS to the Facturolia API, processed in memory and discarded. Requires FACTUROLIA_API_KEY; 10 MB limit; rate limited per key tier.
