We have an API mock server that returns fake data for testing purposes.
You can easily try out our API on the Docs page without an API key:
https://www.listennotes.com/api/docs/?test=1

Instead of using the production base url https://listen-api.listennotes.com/, just use the mock server base url with https://listen-api-test.listennotes.com/. For example, you can send requests to https://listen-api-test.listennotes.com/api/v2/search?q=startup.
If you use one of our official libraries (e.g., podcast-api-python) and you don't set the api_key value, then all requests will hit our mock API server.
Please note that there are limitations of our mock API server:
All requests will return hardcoded fake data.
For the same endpoint, it'll return the same fake data, no matter what parameters you pass to the endpoint. For example,
GET /search?q=startup
andGET /search?q=hello
will return the same response data.The mock server may be down from time to time.
