~1.5 KBTypical response size
Moderate attention impact (1.26% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

}
🟒parse_invoice(content, content_base64)

Extract the invoice as normalised JSON: number, dates, seller, buyer, lines, VAT breakdown, totals, payment details. Works for every supported format.

    "content": {

🟑fix_invoice(content, content_base64, totals, dry_run, values)

Fix validation errors of an EN 16931 invoice (XRechnung, Peppol BIS, ZUGFeRD/Factur-X XML, UBL, CII) deterministically: empty elements, decimals, date and code formats, specification ids; with totals=true also recalculates totals and the VAT breakdown from the lines. Data that is not in the file (Leitweg-ID, seller contact, endpoint ids, payment terms) is taken from "values"; missing ones are listed in needs_input. Returns the change list, the remaining errors and the corrected XML. Counts as 2 requests.
