Imagga API vs Yandex Vision OCR

Imagga API provides image-recognition services for analyzing, organizing, searching, and moderating visual content. Its REST API uses an API key and secret, and the service offers cloud and on-premise deployment. Image and video tagging can assign relevant keywords, including tags trained for customer-specific needs. Other listed tools include categorization, face recognition, OCR, visual search, color extraction, cropping, background removal, and content moderation. Visual Search finds similar images by semantics, color, category, or functional similarity. The Free plan costs nothing and includes 100 API requests; it is intended for testing, with users asked to credit Imagga and link to its site. Indie costs $79/mo, and Pro costs $349/mo. Enterprise pricing is custom-built. Documentation includes examples in cURL, Python, PHP, Java, Ruby, Node.js, Objective-C, Go, and C#. The API is available on web and self-hosted platforms, and the company is based in Sofia, Bulgaria.

Yandex Vision OCR recognizes printed and handwritten text in images and PDF files. Its models cover general page text, multi-column layouts, handwriting, tables, Markdown text, and mathematical formulas. Document-template models can recognize passports, driver licenses, vehicle registration certificates, and license plates, and return template fields. The service is accessed through gRPC or REST APIs. Results arrive as JSON Lines and can include recognized text and language, page, block, line, word, and image positions, plus layout types such as titles, headers, footnotes, and lists. Supported formats are JPEG, PNG, and PDF. The API accepts files up to 10 MB and images up to 20 megapixels; asynchronous PDF requests can cover up to 200 pages. Results remain on the server for three days. Each successful image or PDF-page recognition counts as one billed unit, while server errors and incorrectly configured requests are not charged. Listed rates range from free for printed text and license plate recognition to $0.01, paid once for several document, handwriting, and table models, billed per unit without VAT. There is no free plan.
