Gemina Invoice OCR API review
A low-cost invoice OCR API with structured extraction and developer-focused tooling.
Reviewed by iTechGuides Editors · Editorial team · Updated Sep 2026
Gemina Invoice OCR API is a developer-focused service for extracting structured data from invoices and other business documents. It returns invoice headers, detailed line items, typed fields, custom-schema outputs, and per-field confidence scores as JSON. Product teams, financial platforms, accounting services, and applications can use its REST API, image URLs, document uploads, webhooks, and official SDKs to add document extraction without adopting a complete accounts-payable workflow.
Pricing is credit-based across the paid plans. Starter costs $0 per month and includes 1,500 FileTag tags per month, free-forever access, FileTag extraction only, and 7-day data retention. Bronze costs $25 per month with 1,000 credits, 1 template, webhooks, 1 GB of included storage, and 100 document-intelligence chats per month. Bronze Plus adds 4,200 credits, 3 templates, 2 GB of storage, and 300 chats for $100 per month. Silver costs $250 per month with 11,000 credits, 5 templates, 3 GB of storage, and 1,000 chats; Gold costs $500 with 24,000 credits, 15 templates, 10 GB of storage, and 3,000 chats. Enterprise offers custom pricing, pay-as-you-go billing, volume discounts, a dedicated account manager, and SLA guarantees.
Its strongest fit is an application that needs invoice fields and line items returned in a structured format. Custom extraction schemas, templates, confidence scoring, human verification, audited corrections, search, aggregation, and document chat extend the core OCR capability. The SDK coverage suits teams working in Node.js, Python, C#, Java, or PHP. Gemina is less suitable for buyers seeking a full accounts-payable system: its published positioning does not include verified purchase-order matching, approval routing, or accounting integrations. Choose it when programmable extraction is the priority; choose an alternative when invoice processing must include downstream AP controls.
