API Key
This application uses the AudD® service as a Music Recognition API. You need a special API token provided by AudD® to use the application. If you don’t have one, you can sign up for a free API token. You can add the key on the onboarding or preferences screen, or just set it in local.properties.
There is also the option to use the app without a token, but please note that this will restrict the number of daily recognitions that can be performed.
I don’t see where is says the first 300 requests are free. The cheapest plan is $5/month for 1000 requests and $0.005 per each additional request. I would only use it once or twice a month, so it’s not worth $5/month. I’d be willing to pay per request like with Chat GPT, but it doesn’t have that option.
