Gemina Invoice OCR API vs Staple AI Accounts Payable

Gemina Invoice OCR API extracts information from invoices and related financial documents, returning headers, line items, and custom schemas as typed JSON with confidence scores. It covers invoices, credit notes, receipts, expense claims, purchase orders, statements, and remittance advice. Extracted invoice fields include vendor details, identifiers, dates, amounts, taxes, discounts, and line-item values such as quantity, unit price, and line total. Each field is rated high, medium, or low confidence, and a human verification flow supports corrections. A reusable schema can be made from one sample document without labeled training data or model fine-tuning. The API offers Invictus, Praetorian, and Velox models with different speed and accuracy tradeoffs, plus an official SDK and REST API. FileTag is available over MCP for compatible agents such as Claude Desktop and Cursor. The product focuses on extraction: it does not provide approval routing, three-way matching, ERP connectors, or a review cockpit. Pricing starts with a free plan; paid plans are from $25/mo.
