The Perplexity AI API is currently in beta release v0. Clients are not protected from backwards incompatible changes and cannot specify their desired API version. Examples of backwards incompatible changes include...
- Removing support for a given model.
- Renaming a response field.
- Removing a response field.
- Adding a required request parameter.
Backwards incompatible changes will be documented here.
Generally, the API is currently designed to be compatible with OpenAI client libraries. This means that, given the same request body, swapping the API base URL and adding your Perplexity API key will yield a response that can be parsed in the same way as the response OpenAI would yield, except for certain explicitly unsupported body parameters documented in the reference (link to reference).
