How do I know which terms are available?

You can use the `list_available_terms` tool to retrieve a complete list of all valid term identifiers and their descriptions.

Can I verify if a term is valid for a specific date?

Yes, the `validate_term_application` tool checks if a specific term can be logically applied to a given invoice date.

What format should the invoice date be in?

The invoice date must be provided in ISO 8601 format.
