API4AI OCR
What it is
API4AI OCR is a paid cloud API for recognizing text in images and PDFs, including printed documents and handwritten manuscripts. It can locate separate words or extract all text, returning results as JSON. The service supports hundreds of modern and ancient languages, including Latin, Cyrillic, Japanese, Chinese, and Arabic, and can recognize multiple languages within one image. Developers call an HTTP POST endpoint with an API key. Code examples are linked for Bash, Python, JavaScript, C#, PHP, and Swift, plus a JSFiddle sample. API4AI describes the service as real-time and names old-publication digitization, election and poll form analysis, and document scanning as uses. Its webpage demo accepts JPG or PNG files smaller than 16 MB. The developer portal uses prepaid pay-as-you-go billing, while the RapidAPI listing uses subscriptions and offers a free plan. Terms say submitted files are discarded after processing and customer data is not used to train AI models.
