How do I get a Perplexity API key?

Log in to the [**Perplexity AI Settings**](https://www.perplexity.ai/settings/api), go to **API Key Management** and click **Create API Key**. Copy the key immediately — it starts with `pplx-` and won't be shown again.

What models are available?

Use the `list_models` tool to see all available Perplexity models. Key models include sonar (web-grounded chat), sonar-pro (enhanced reasoning), sonar-reasoning and sonar-reasoning-pro. Each model provides real-time web search with citations.

Can I filter search results to specific domains?

Yes! Use the `chat` or `search` tools with the search_domains parameter to limit results to specific websites (e.g. ["wikipedia.org","github.com"]). This is useful for research focused on trusted sources.

Do responses include citations?

Yes! All Sonar models return responses with inline citations and a list of source URLs. The citations are embedded in the response text as numbered references [1], [2], etc., and the full source URLs are provided in the response metadata.
