One Endpoint Is All You Need: /ocr

The current API uses a single-endpoint design with an extremely low integration barrier:

  • Required parameter: image (supports multiple image formats)
  • Optional parameter: format (defaults to text, can be set to docx to return a DOCX file)
  • Return structure: by default returns JSON where the text field contains the complete sequentially extracted text; when format=docx, returns a DOCX file

Plans and Pricing

  • Free tier: suitable for development and debugging
  • Basic pricing: $1 / 1,000 images
  • Large customer and volume discounts: negotiable on demand

For enterprise/compliance scenarios, please contact us for customized solutions.

Privacy and Security

  • No storage: images and recognized text are not saved, discarded upon request completion
  • No tracking: no user tracking unrelated to recognition
  • Full encryption: transmission security ensured via HTTPS
