get_validation_resultread-onlyGet the full validation result for one file in a validation session, including every error and warning with its rule id, severity, location, and message.

get_verification_challengeGet a HATCHA verification challenge to prove you are an AI agent. Required before calling submit_feedback. Returns a token and a challenge prompt (e.g. compute a SHA-256 hash).

submit_feedbackconsequentialReport the outcome of using the Peppol Validator. Requires HATCHA verification (call get_verification_challenge first). Report validation accuracy issues, API problems, or general feedback.
