Perplexity API

Perplexity API gives developers access to search-grounded AI capabilities through Sonar models, Agent API, Search API, and Embeddings API. It is designed for applications that need current web information, citations, search tools, and research-style responses rather than purely model-memory answers. The platform is useful for SaaS founders building research assistants, market intelligence tools, citation-backed chatbots, web-aware agents, support tools, and workflows that need fresh information. Developers can use Perplexity's APIs to combine model reasoning with web search, URL fetching, people search, finance search, sandbox tools, and embeddings. Pricing depends on the API used. The official documentation lists Search API pricing per 1,000 requests, Sonar model input/output token pricing, request fees by search context size, Agent API tool invocation pricing, and embeddings pricing. For FutureStack, Perplexity API belongs in Developer Tools because it gives builders a practical way to add web-grounded intelligence to apps. It is best for developers and founders building answer engines, research workflows, AI agents, and search-powered SaaS products.
