Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• calculate_vat unknown never probed

  Calculate EU VAT (Dutch: BTW) for a cross-border or domestic sale, using the destination-country principle that applies to e-commerce. Handles the cases sellers get wrong: OSS distance selling to another EU country, B2B reverse charge when the buyer has a VIES-valid VAT number, and zero-rated exports outside the EU. Rates are the statutory ones for the destination country, including reduced rates when a category is given.

• validate_iban unknown never probed

  Validate an IBAN (bank account number) and report whether its check digits and country-specific length are correct. Catches transposed or missing digits before a payment or an invoice goes out with the wrong account number. This checks the number's structure, not whether the account exists or who owns it.

• bol_commission unknown never probed

  Work out what bol.com keeps from a sale: the commission percentage for the product category, any fixed fee, and what the seller is left with. Category names are the Dutch ones bol.com uses ("Elektronica", "Boeken", "Speelgoed"). If the category is unknown or missing, the tool returns the list of categories it knows, so call it again with one of those.
