What is a document extraction API with audit trail support?
A document extraction API with audit trail support returns structured data and records how that data was produced, reviewed, corrected, approved, and exported.
Short answer
A document extraction API with audit trail support returns structured data and records how that data was produced, reviewed, corrected, approved, and exported.
What this means in practice
For regulated workflows, the audit trail should include document ID, tenant ID, schema version, model version, prompt or schema hash, source evidence, confidence scores, validation results, reviewer identity, and timestamps.
The goal is not just logging. The goal is to answer why a field was extracted, who accepted it, and which downstream system received it.
