How this service works
Verified invoice extraction for autonomous agents - PDF to structured JSON with arithmetic reconciliation and honest confidence
Output
A structured JSON object containing extracted invoice fields such as vendor name, invoice number, issue date, due date, line items (description, quantity, unit price, subtotal), subtotals, tax amounts, grand total, and a confidence score indicating how reliably the arithmetic reconciles across the extracted figures.
Example use cases
Accounts payable automation pipeline
“I just received a vendor invoice as a PDF at https://acme.com/invoice-march.pdf — can you pull out all the structured data including line items, totals, and due date, and flag if the numbers don't add up?”
Expense report verification
“We have a supplier invoice PDF at https://storage.example.com/supplier-inv-8821.pdf — extract the line items and totals and tell me whether the arithmetic reconciles correctly so I can approve it.”
Invoice ingestion for ERP system
“I need to import this contractor invoice into our system — can you parse the PDF at https://contractor.io/invoice-q1.pdf into structured JSON with all the fields like amount, tax, and vendor info?”
Technical details
Endpoint
GEThttps://invoice-extract.fly.dev/v1/bazaar/invoice/extractWhen to prefer
Choose this endpoint when you need to extract structured, machine-readable data from a PDF invoice with built-in arithmetic validation — particularly useful in autonomous agent pipelines where you need reliable confidence signals before passing data downstream to accounting or ERP systems. Prefer it over generic OCR tools when invoice-specific field recognition and reconciliation checks are needed.
Side effects
- PDF URL is not publicly accessible or returns 403/404 — extraction fails with an access error
- PDF is scanned/image-based with poor OCR quality — low confidence score or missing fields
- Invoice format is highly non-standard or handwritten — partial extraction with low confidence
- URL points to a non-PDF file type — endpoint returns an error or empty result
- Arithmetic does not reconcile — returned with a low confidence flag, not an error per se
- Network timeout fetching large PDF files
