The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

For XRechnung, set profile to XRECHNUNG and choose CII or UBL syntax. When the buyer is a German VAT-registered business (DE-prefixed VAT id), the Wachstumschancengesetz B2B mandate (effective 2025-01-01, §14 Abs. 2 UStG) requires a structured EN 16931 invoice.

Returns a structured validation report with errors and warnings. Supports all ZUGFeRD profiles (MINIMUM through EXTENDED) and XRechnung (CII and UBL syntax). Profile and syntax are auto-detected if not specified. By default this validator runs entirely locally (Schematron only). Set cloud_validate=True (or EINVOICING_DE_KOSIT_ENABLE=1) to opt in to sending the invoice XML to a remote KoSIT endpoint. Doing so egresses the full invoice payload.
| Name | Type | Req | Description |

| strict | boolean | – | If True, warnings are also reported. If False, only errors are returned. |
| syntax | – | – | Override syntax detection. One of: CII, UBL. If omitted, auto-detected from the XML root element namespace. |
| use_local_only | – | – | [Deprecated] Use cloud_validate instead. use_local_only=True is equivalent to cloud_validate=False, which is now the default; this alias is retained for one release and will be removed. |
| xml_base64 | – | – | Base64-encoded XML bytes of the invoice. |
| xml_content | – | – | Raw XML string of the invoice to validate. Provide either xml_content or xml_base64, not both. |
