Perplexity Async Chat Completions API is one of 12 APIs that [Perplexity](https://apis.io/providers/perplexity/) publishes on the [APIs.io](https://apis.io/) network, described by an AsyncAPI event-driven specification. Tagged areas include Artificial Intelligence, Asynchronous, Chat Completions, and Large Language Models. The published artifact set on APIs.io includes API documentation, an API reference, authentication docs, and an AsyncAPI specification.

The Async Chat Completions API enables developers to submit long-running chat completion requests for background processing. Requests are queued and processed asynchronously, returning a unique identifier for tracking status through creation, processing, completion, or failure stages, making it ideal for deep research and computationally intensive queries.
