mpxpy

The official Python client for the Mathpix API. Process PDFs and images, and convert math/text content with the Mathpix API.

Setup

Installation

pip install mpxpy

Authentication

You'll need a Mathpix API app_id and app_key to use this client. You can get these from Mathpix Console.

Set your credentials by either:

• Using environment variables
• Passing them directly when initializing the client

MathpixClient will prioritize auth configs in the following order:

1. Passed through arguments
2. The ~/.mpx/config file
3. ENV vars located in .env
4. ENV vars located in local.env

Initialization

Using environment variables

Create a config file at ~/.mpx/config or add ENV variables to .env or local.env files:

MATHPIX_APP_ID=your-app-id
MATHPIX_APP_KEY=your-app-key
MATHPIX_URL=https://api.mathpix.com  # optional, defaults to this value

Then initialize the client:

from mpxpy.mathpix_client import MathpixClient

# Will use ~/.mpx/config or environment variables
client = MathpixClient()

Using arguments

You can also pass in your App ID and App Key when initializing the client:

from mpxpy.mathpix_client import MathpixClient

client = MathpixClient(
    app_id="your-app-id",
    app_key="your-app-key"
    # Optional "api_url" argument sets the base URL. This can be useful for development with on-premise deployments
)

Process PDFs

Basic Usage

from mpxpy.mathpix_client import MathpixClient

client = MathpixClient(
    app_id="your-app-id",
    app_key="your-app-key"
)

# Process a PDF file with multiple conversion formats and options
pdf = client.pdf_new(
    url="http://cs229.stanford.edu/notes2020spring/cs229-notes1.pdf",
    convert_to_docx=True,
    convert_to_md=True,
)

# Wait for processing to complete. Optional timeout argument is 60 seconds by default.
pdf.wait_until_complete(timeout=30)

# Get the Markdown outputs
md_output_path = pdf.to_md_file(path='output/sample.md')
md_text = pdf.to_md_text() # is type str
print(md_text)
# Get the DOCX outputs
docx_output_path = pdf.to_docx_file(path='output/sample.docx')
docx_bytes = pdf.to_docx_bytes() # is type bytes
# Get the JSON outputs
lines_json_output_path = pdf.to_lines_json_file(path='output/sample.lines.json')
lines_json = pdf.to_lines_json() # parses JSON into type Dict
