What APIs are included in the Perplexity API Platform?

The platform includes four main APIs: Agent API for third-party AI models with web search, Search API for ranked web results, Sonar API for web-grounded AI responses, and Embeddings API for generating text embeddings.

How do I authenticate and get started with the API?

Generate an API key from the Perplexity API Portal, then set it as an environment variable (PERPLEXITY_API_KEY). SDKs for Python and Node.js are available for quick integration.

What programming languages are supported by the SDKs?

The official SDKs support Python 3.8+ and Node.js, providing type definitions and both synchronous and asynchronous clients.

What is the pricing model for the Perplexity API Platform?

It offers direct provider pricing with a single key and one bill, making it cost-effective compared to managing multiple vendors separately.
