About Perplexity Sonar API

"Real-time web search API for building apps with up-to-date, cited AI responses"

Perplexity Sonar is the API powering Perplexity's renowned real-time web search capabilities, now available for developers to integrate into their own applications. Sonar enables building applications that can answer questions with up-to-date web information, providing cited, grounded responses rather than potentially outdated LLM knowledge. The API offers online models that search the web in real-time before responding, making it ideal for news summarization, current events Q&A, and any application requiring fresh, factual information with source citations.
