A podcast search screen has one main job: help someone choose a show or an episode. Start there. A page with many filters can still fail if the listener cannot understand a result.
Decide what the search returns
A show is a series. An episode is one item in that series. Label these results clearly. For a show, display its name, publisher and cover. For an episode, add the show name and publication date. Use a stable ID for links. A title can change.
Try three example searches in your plan: a known show, a broad topic and a word with a spelling mistake. Use these three searches when you test your first version.
Put the secret key on your server
Your browser or mobile app should call your own backend. That backend can call the podcast API with its secret key. Do not include a secret in a public JavaScript file or a mobile app bundle. A hidden input is not a safe place for a key.
Set a short timeout. If the service is unavailable, keep the search text and show a retry option. Do not label a service error as “no podcasts found”. Those are different problems.
Keep the next page simple
Ask for a small result page. Follow the API's documented next-page value. If it returns a cursor, treat that cursor as an opaque value: pass it back without trying to calculate it. Clear old results when the query changes.
The Podcast Index documentation is a useful example of the fields and endpoint groups a podcast data service can expose. Each provider has its own request and response contract; do not copy field names between services without checking.
Give an empty search a useful next step
Suggest a shorter query or a different result type. Keep the message calm. A user should not need to learn how the catalog works.
Start with one result card and one error state. Make both clear before adding more filters.
Podnivo is prelaunch. Read about its podcast search API and check the published API contract before integration.
