Mouser Python API

Project description

Mouser Python API

License: MIT Python Versions PyPI Style | Tests



  • Tested with Python 3.7+
  • Dependencies: click and requests packages

Mouser API Keys

Mouser provides two separate API keys:

  • one for the cart and orders
  • one for part searches.

Go to Mouser's API hub to request the keys.

To store the keys, two options:

  • create two environmental variables MOUSER_ORDER_API_KEY and MOUSER_PART_API_KEY with the respective values of each key
  • create a file named mouser_api_keys.yaml with the order API key on the first line and the part API key on a second line.

The keys will be automatically loaded for each API request.



pip install mouser


  1. Create virtual environment and activate it
  2. Run pip install -r requirements.txt


  1. Install poetry package: pip install poetry
  2. Run poetry install







poetry run mouser


This command line tool reflects the usage from Mouser's API structure documented here.
The first positional argument is the category of the request: cart (for MouserCart), order, history (for MouserOrderHistory) and search (for SearchAPI). The second argument is the type of operation from the list of operations for each category.

Run mouser --help for more information about the usage.


The examples below assume this package was installed using Pip (for more options, see above)

Part Number Search

mouser search partnumber --number XXX

Export order to CSV

mouser order get --number XXX --export
