If you want to expose an API endpoint inside your local network during development work you can use Uvicorn. The normal method of launching an App using Uvicorn is:

uvicorn your_apps_name_here:app --reload

This defaults to serving it only on that machine at default location http://127.0.0.1:8000/. To set it up sot that it serves the page at your computer’s IP address launch it with this command instead:

uvicorn your_apps_name_here:app --reload --host 0.0.0.0

You can also change the port by adding the port flag and the desired port, for example:

uvicorn your_apps_name_here:app --reload --host 0.0.0.0 --port 5000

Alternatively, you can launch the Uvicorn server programmatically from with your Python code by adding Uvicorn to your import statements and then adding the Uvicorn commands to the name=”main” statement:

if __name__ == "__main__":
    uvicorn.run("your_apps_name_here:app", host="0.0.0.0", port=8000, log_level="info")

Then you launch the app from Python:

$ python your_apps_name_here.py


See the Uvicorn documentation for more information.


Disclaimer This assumes that you are behind a firewall that will not allow access to that address/port. If you don’t know this for sure then don’t use this method.

Thanks to João Pedro’s article on Towards Data Science for getting me started with Uvicorn.
