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.

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'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.
