Perplexity API
From AI API data terms: training, retention and zero retention: What does each AI provider say happens to data sent to its commercial API: is it used for training, how long is it kept, and can zero retention be had?
Provider: Perplexity
The company offering the API, as named on its own page.

Trains on API data by default: No
True or false only where the text plainly says what happens to this offering's API data with no opt-in or opt-out by the customer. An opt-out with no stated default is left blank. Where pages differ: legal or privacy page first, then help or trust pages, then developer docs, with the other in conflicts.

Default retention: Retention, use, and security practices vary by API, model, and account configuration
How long prompts and outputs are kept by default, in the provider's words. Where pages differ: legal or privacy page first, then help or trust pages, then developer docs, with the other in conflicts. A page that's only less specific isn't a conflict: the more specific statement is the value.

Exceptions: Some providers require limited retention as a condition of offering their models
The main case with different retention, in the provider's words: first a model carved out of the general promise, then a feature, then a case such as flagged content. Pages rank as for Default retention; between pages of equal rank, the one naming the models. One passage only, so others may exist.
Models served by third-party providers are also subject to those providers’ terms and policies. Some providers require limited retention as a condition of offering their models.
