What it does

One API, many documents

Invoices and receipts through a single endpoint with a consistent response shape.

Structured, not raw text

Named fields and line items you can use directly — no post-processing of OCR text.

Confidence on every result

Each response includes a confidence score so you know what to trust and what to review.

Looking for a specific document type? See the Invoice Parser API and the Receipt OCR API.

How the extraction works
  1. Read — the document is converted to text with OCR (for images) or parsed directly (for digital PDFs).
  2. Parse — deterministic rules pull out each field and line item and normalize dates and amounts.
  3. Check — the result is scored for confidence: totals are reconciled (subtotal + tax = total), required fields are verified, and formats are validated.
  4. Review — if confidence is below 100, the document is sent for a second pass by an AI model that re-checks only the uncertain fields. High-confidence results skip this step entirely.

Every response includes a confidence score and a needs_review flag, so you always know which results to trust and which to double-check.
