How this service works
Recognize handwritten math/text from stroke coordinate data (digital ink). Returns LaTeX and Mathpix Markdown.
Output
Returns a structured object containing the recognized mathematical content in the requested output formats (text, data, HTML, latex_styled), optionally with custom math delimiters applied and whitespace normalized according to rm_spaces and rm_fonts settings.
Example use cases
Example prompt
“I have stroke coordinate data from a handwritten math equation — the x arrays are [[10,20,30],[50,60]] and y arrays are [[5,15,25],[40,50]] — can you run it through Mathpix and give me back the latex_styled output with display math delimiters?”
Technical details
Endpoint
POSThttps://mathpix.mpp.paywithlocus.com/mathpix/process-strokes?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have raw digital ink or stylus stroke coordinate data (arrays of x/y points per stroke) and need to convert it to LaTeX or other math-friendly formats. It is specifically designed for pen/tablet input rather than image files — prefer the Process Image endpoint when you have a raster image of handwritten math instead.
Side effects
- Invalid or malformed stroke data JSON returns a 400 error
- Empty stroke arrays may result in empty or low-confidence output
- Unsupported format string values may cause a 422 validation error
- Stroke data representing non-mathematical content may yield poor recognition quality
- Network timeout if stroke payload is extremely large
