Perplexity’s Post

Introducing Perplexity Search API We've built a search index of billions of webpages to provide real-time, quality information from the web. Now developers have access to the full power of our index, providing the most accurate results in milliseconds. https://lnkd.in/g42QMUj9 With Microsoft retiring the Bing Search APIs in August, legacy search engines have abandoned the developer community who need real-time access to information. We're stepping in to provide a search API designed for the new retrieval paradigms introduced by frontier AI systems. We built Perplexity Search API around three criteria: 1. Completeness + freshness + speed 2. Fine-grained content understanding 3. Hybrid retrieval and ranking. The system processes ~200M daily queries using distributed crawling/indexing, multi-stage ranking, and dynamic parsing. We use AI to dynamically parse websites, continuously refining how it extracts and segments high-quality, meaningful content. LLMs drive a self-improvement loop, balancing completeness and quality to keep the index fresh and accurately divided into spans for precise retrieval. After releasing the Perplexity Search API and SDK, we developed a simple, neutral evaluation framework to benchmark search APIs as used by AI agents We compared our API and found state-of-the-art results on both quality and latency, removing the tradeoff between speed and accuracy. Perplexity stands as both the fastest and highest-quality API on the marketplace. We deliver a median latency of 358ms—over 150ms faster than the next-best provider—while keeping 95th-percentile latency under 800ms. Perplexity Search API achieves leading quality across single-step and deep research benchmarks, consistently outperforming competitors.
