Api Endpoint

Subpay invoice reader

Reads invoices, bills and receipts from PDF into structured JSON — vendor, customer, dates, PO, line items, discount, tax, shipping, total, balance due — and checks the arithmetic: quantity × unit price, lines to subtotal, tax rate, total and balance due. The response says exactly which figures don't add up. $0.04 per page (up to 25 pages), quoted per document.
