Cloudmersive OCR API vs Yandex Vision OCR

Cloudmersive OCR API converts scanned documents and photos of documents or receipts into text using deep-learning OCR. It lists support for more than 90 languages, including English, simplified and traditional Chinese, French, Spanish, German, and Italian. For document and receipt photos, the API can locate the item and correct skew or rotation before recognition. Receipt extraction can return business name, address, phone number, total, and date. Image and photo endpoints offer Basic, Normal, and Advanced recognition modes; an OCR task may consume multiple API calls, including when processing a multipage PDF. The free tier costs nothing and includes 600 calls monthly, one call per second, and a 3.5 MB maximum file size. Using a free-tier key with OCR endpoints requires adding a credit card, and the free tier allows one simultaneous request. Paid plans start at $19.99 a month. Deployment options include public cloud, dedicated managed instances, private cloud, on-premises, PaaS, and government cloud. Cloudmersive says its stateless APIs do not retain payload data after a transaction and its endpoints use HTTPS with TLS 1.2 or later.

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.
