Perplexity Sonar

LLM-powered search API with built-in citations, offering multi-tier model options from fast to deep research.

AI search APIs are the infrastructure layer that gives large language models access to current web information. Unlike traditional search engines, these APIs return semantically relevant, structured results optimized for retrieval-augmented generation (RAG) and AI agent workflows. They're essential for any AI product that needs to answer questions about the real world beyond its training data.

Editorial assessment

Unique in that it returns LLM-synthesized answers with citations, not raw search results. Great for question-answering and research agents. But you're paying for inference plus search — at $1/$1 per M tokens (Sonar) to $3/$15 (Pro) — making it expensive for high-volume pipelines where you just need links and snippets.

Exa

Exa returns raw results you can process with your own LLM, giving you more control over output and lower per-query cost.

You.com

You.com's Research API offers similar depth with more transparent sourcing and composable query types.

Tavily

Tavily is simpler and cheaper for basic agent search where you don't need LLM-synthesized responses.
