A4.2/5.0

Scored across 6 tools

Disambiguation4/5

Each tool has a clear, distinct role: creation, validation, PDF extraction, rule explanation, Leitweg-ID checking, and Peppol lookup. Mild overlap exists between check_leitweg_id (which also reports Peppol registration) and peppol_lookup, and between check_leitweg_id and validate_einvoice, but the descriptions make the boundaries reasonably clear.

Naming Consistency4/5

Five of six tools follow a clean verb_noun snake_case pattern (check_, create_, explain_, read_, validate_). peppol_lookup is a noun-based name that breaks the pattern slightly, but it remains readable and unambiguous.

Tool Count5/5

Six tools form a tight, end-to-end e-invoicing workflow (read PDF -> create -> validate, plus lookup/explain/check helpers). Every tool earns its place with no filler or redundancy.

Completeness4/5

The surface covers the full create-validate-extract-lookup lifecycle with useful helper tools. A gap exists in that there is no tool to parse an existing e-invoice XML/PDF back into structured data (only validation), which could be a minor dead end for round-tripping.

Available Tools

6 tools
check_leitweg_idCheck a Leitweg-IDA
Read-only
Inspect

Check a German Leitweg-ID (buyer reference BT-10 for invoices to German public authorities) against the official format and check digit (spec v2.0.2), and whether the authority is registered on Peppol (peppol_registered). Returns validity, the parts and the expected check digits.

Inputs: leitweg_id (required), lang.

create_einvoiceCreate an e-invoiceA
Read-only
Inspect

Create a valid e-invoice from structured data: XRechnung 3.0 (UBL or CII), ZUGFeRD / Factur-X PDF (EN 16931) or Peppol BIS Billing 3.0. The file is checked with the official KoSIT validator before it is returned; if it fails, you get the rule errors instead of a file. XML comes back as text in xml, the ZUGFeRD PDF as base64 in pdf_base64. XRechnung needs a seller contact (contact, phone, email), a buyer email or Peppol ID (electronic address), a buyer_reference (Leitweg-ID for German authorities) and payment details (iban). Peppol needs peppol_id for seller and buyer.

Inputs: buyer (required), lines (required), number (required), seller (required), +22 more.

explain_ruleExplain a validation ruleA
Read-only
Inspect

Explain an e-invoice business rule code (EN 16931 BR-, BR-CO-, XRechnung BR-DE-, Peppol PEPPOL-EN16931-): official text (with an English translation for German-only rules), plain-language meaning, severity, the fields (BT/BG) involved and a link to the reference page.

Inputs: code (required).

peppol_lookupPeppol participant lookupA
Read-only
Inspect

Check whether a company can receive e-invoices over Peppol. Accepts a Peppol ID (e.g. 0208:0123456749), a VAT number (e.g. BE0123456749, NL...B01) or a Belgian enterprise number. Returns each matching participant ID, whether it is registered, whether it accepts Peppol BIS invoices, and name/country from the Peppol Directory when published.

Inputs: query (required).

read_invoice_pdfRead a PDF invoiceA
Read-only
Inspect

Read an ordinary (non-e-invoice) PDF invoice and return its data in the input format of create_einvoice: seller and buyer (name, address, VAT ID, country), invoice number, dates, IBAN/BIC, Leitweg-ID and the invoice lines (only if quantity x price and the line sum match the PDF's net total; otherwise one line with the net total). Regex-based, no guessing: fields we can't read reliably are missing and listed in missing. Check and complete them, then call create_einvoice to get XRechnung, ZUGFeRD or Peppol. Scanned PDFs (no text layer) are not supported. Pass the PDF base64-encoded in file_base64. Max 5 MB.

Inputs: file_base64 (required).

validate_einvoiceValidate an e-invoiceA
Read-only
Inspect

Validate an e-invoice (XRechnung UBL/CII, ZUGFeRD / Factur-X PDF, Peppol BIS Billing 3.0, EN 16931) with the official KoSIT validator. Returns valid/invalid, the detected format, every error and warning with its rule code, and the exact corrected value for common calculation errors. Pass the XML as text in xml, or a PDF/XML file base64-encoded in file_base64. Max 5 MB.

Inputs: xml, france, file_base64.
