Aspose.OCR Cloud for cURL is a powerful, cloud-based REST API that enables text extraction from images, scanned PDFs, screenshots, and smartphone photos directly through the command line. It requires no software installation—any environment capable of executing cURL commands or Bash scripts can use the service instantly. Developers can also integrate the API with third-party REST tools such as Postman. The solution supports Latin, Cyrillic, Middle Eastern, Indic, and Asian scripts and can recognize over 6,000 Chinese characters. Recognition results can be returned in widely used data exchange formats, including plain text, JSON, searchable PDF, Excel, CSV, and hOCR.
