You may be receiving an Axios error that your API key is invalid if the key you are using does not match the API key provided by the API's service. This can be caused by typos in the API key, or if the API key has expired. Check that the API key matches the API key provided by the API's service and make sure it is up to date.

The Axios Error 400, also known as a Bad Request error, indicates that the request sent to the server was invalid or cannot be fulfilled. This generally occurs when the request is structured incorrectly or is missing certain required parameters. The server may also reject the request depending on the specific circumstances or if it fails certain validation tests.
