A podcast catalog helps an app find shows and episodes. It does not turn the publisher's audio, cover art, transcript, or brand into material your business owns.
This distinction matters early in a product. Search, playback from a publisher's enclosure, offline copies, transcript processing, and republishing are different activities. They may involve different permissions and platform terms.
Write down the actual use
Describe what your app does with each kind of content. For example: display a title and link, stream the publisher's audio address, keep a local download for one listener, or create a new public audio copy. Avoid treating all four as simply “using the API.”
Review the provider's developer terms and the publisher's stated conditions. Where a planned use is unclear, get advice for that specific use rather than assuming that a publicly reachable URL is unrestricted.
Keep source links and publisher attribution where they are helpful. Make it possible to refresh metadata when a publisher updates or removes a record. Do not promise permanent availability for content your app does not control.
Add a product review checkpoint
Before releasing a feature that stores or transforms audio, ask who controls the file, how long you keep it, who can access it, and how removal works. The answers may change your architecture as well as your terms.
A technical integration guide can explain the data path, but it cannot decide every legal question for every country. Treat rights review as part of the feature's design.
Podnivo's catalog pages separate API access from publisher content rights. Keep that same separation in your own product copy so listeners and partners understand what the integration actually provides.
