Perplexity's Sonar API occupies the grounded-answer layer of the API stack: a web search endpoint built for developers who need real-time, cited answers pulled from live web sources rather than a static model's training data, sitting alongside Perplexity's broader API platform of search, embeddings, and gateway endpoints for building AI applications. The product line itself is in transition. Sonar's chat-completions endpoint is being folded into a newer Agent API built to connect external tools and data to agent workflows. Tracked conversation about the product specifically is quiet so far, consistent with a developer tool still early in independent visibility outside its parent's broader platform.

Business Profile
The Sonar API sits inside Perplexity AI, founded in 2022, which has scaled headcount rapidly as its consumer search product and developer API business have both grown. The company's API platform has expanded beyond the original Sonar search-and-cite endpoint into a broader suite, now spanning an Agent API, a model-agnostic Gateway API, a raw Search API, and an Embeddings API, reflecting a shift from a single grounded-search product toward a fuller developer platform for building AI applications on top of Perplexity's web-scale index.

Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
Perplexity's agent-facing build-out centers on the Agent API, the evolution of the original Sonar chat-completions endpoint, which returns cited, real-time web answers and lets developers connect external tools and data sources through MCP or custom function definitions. Alongside the model-agnostic Gateway API and a raw Search API, Perplexity documents a dedicated MCP endpoint for connecting agents directly to its search and citation capabilities, extending the original grounded-answer product into infrastructure built for agent tool use.
