All Convert API endpoints

v3/text
Process an image
This is our most widely used endpoint. You can use this endpoint to OCR individual images of handwritten and printed equations, handwritten and printed text, tables, and diagrams to get digital formats like LaTeX, Asciimath, and MathML.
Developer Docs

v3/pdf
Process a PDF
Use this endpoint to OCR PDFs and convert them to other formats. This endpoint works asynchronously, since large PDF files can take several minutes to process. v3/pdf accepts PDF files and URLs in the request.
Developer Docs

v3/strokes
Process strokes (digital ink)
Use this endpoint to add stroke recognition (i.e. digital ink) to your app. This endpoint works for all math, and for Hindi and Latin alphabet language text. You can process the data for each individual stroke, or you can use a session_id for live drawing capabilities in your app.
Developer Docs

v3/batch
Process a batch of images
Use this endpoint to process multiple images in a single POST request. The request will return a batch ID which is queried with a GET request once an appropriate amount of time has passed for the images to process. You should only use the batch endpoint if your workflow is not latency sensitive.
