## About the Tool

Perplexity API gives developers APIs for applications that need current web information, search, citations, and AI-generated answers. Its platform includes Agent API, Search API, Sonar, and Embeddings, covering raw search, web-grounded responses, multi-model agents, and semantic retrieval.

For founders building AI products, it is useful for research assistants, market-intelligence tools, citation-backed chat, web-aware agents, answer engines, and search experiences that need information beyond static model knowledge.

Search API can provide ranked web results, Sonar can produce cited answers, Agent API can access third-party models and tools, and Embeddings can support semantic search and RAG. Developers can use REST or SDK access and stream responses.

Use Perplexity API when web grounding is core to your product. Because pricing is usage-based, builders should estimate requests, search context, token usage, tool calls, and rate limits before scaling.
