Extract a License Plate from an Image #ALPR

ALPR – Or Automatic License Plate Recognition is the process of extracting the textual elements of a License Plate from an image. For example, reading the text FL802FJ from the image shown above.

Here is an API on Rapid API that offers a simple API that reads the license plate from an image of a car when provided via a URL: https://rapidapi.com/appaio/api/license-plate-from-image/

You make a HTTP POST request to the following endpoint:

https://license-plate-from-image.p.rapidapi.com/PlateRecognizerLambda

With the JSON Body;

{"url":"https://i.ytimg.com/vi/WPXs6vNiSb4/maxresdefault.jpg"}

And the x-rapidapi-key set in the HTTP Headers.

Which results in the following:
