What API4AI OCR is
API4AI OCR is a cloud-based service that analyzes pictures and recognizes text in printed documents and handwritten manuscripts. It can locate separate words or extract all text from an image, and it returns detected words from images or PDFs as JSON. The service supports hundreds of modern and ancient languages, including Latin, Cyrillic, Japanese, Chinese, and Arabic, and can recognize multiple languages in one image. Developers can send HTTP POST requests to its endpoint and authenticate with an API key; code examples are linked for several languages, alongside a JSFiddle sample. The service is offered through API access. Its developer portal uses prepaid pay-as-you-go billing, deducting API usage from a prepaid balance, while its RapidAPI listing uses subscriptions and offers a free plan. The webpage demo accepts JPG or PNG files smaller than 16 MB. API4AI says submitted files are discarded after processing and customer data is not used to train AI models. The page also offers tailored customization discussions and lists a contact email.
