Neural search API specifically designed for AI applications, offering semantic search capabilities, structured data extraction, and high-quality web indexes optimized for agent workflows.
Neural search API that understands context and meaning, helping AI agents find relevant web information beyond simple keyword matching.
Exa revolutionizes how AI applications access web data through its neural search API that understands semantic meaning rather than just keyword matching. Unlike traditional search APIs that rely on keyword frequency and basic ranking algorithms, Exa's neural search engine finds content based on conceptual similarity and context, making it invaluable for AI agents that need to understand and reason about web information.
The platform offers dedicated high-quality web indexes for different domains including people, companies, code documentation, financial data, and news content. Each index is specifically optimized for accuracy and relevance within its domain. Exa's token-efficient content extraction uses intelligent highlighting to extract the most relevant excerpts from web pages, significantly reducing token consumption while maximizing context quality for Large Language Model applications.
Exa provides multiple latency profiles to meet different application needs. Exa Instant delivers sub-200ms response times for real-time agent workflows where search cannot become a bottleneck. Standard neural search typically responds within 1-3 seconds with comprehensive results. The platform's structured output support means AI applications receive properly formatted data ready for immediate LLM consumption, eliminating the need for additional processing steps.
Unlike generic search APIs, Exa understands the specific requirements of AI applications. The platform provides features like similarity search (find pages similar to a given URL), semantic content discovery that goes beyond keyword matching, and agentic search capabilities designed for deep research tasks. Built-in summarization features can process search results directly, providing concise overviews perfect for AI decision-making processes.
The enterprise-grade infrastructure includes SOC 2 Type II certification, zero data retention options for privacy compliance, and single sign-on integration for team management. Exa is trusted by leading AI companies building intelligent agents, research tools, and applications that need reliable, accurate web data integration. The API is specifically designed for developers creating AI agents that need to ground artificial intelligence in current, real-world web information.
Compared to traditional search APIs like Google Custom Search or Bing Search, Exa excels at understanding context and finding conceptually relevant content that keyword-based systems miss entirely. While it may have smaller index coverage than Google-scale providers, the semantic understanding and AI-optimized features make it significantly more valuable for applications where search quality matters more than raw coverage.

Exa's neural search engine excels at finding content that keyword-based search APIs miss entirely, making it invaluable for AI agents doing research and discovery. The smaller index means some coverage gaps, but semantic search quality is often superior to traditional alternatives.
A purpose-built embeddings-based web index that ranks results by semantic meaning, allowing AI agents to issue natural-language queries and retrieve conceptually relevant pages even when keywords do not match.
Fetches clean, parsed text, summaries, and highlights from any URL returned by search (or supplied directly), removing the need for custom scraping, boilerplate stripping, and HTML cleanup in RAG pipelines.
Returns a synthesized natural-language answer with inline citations from the open web, enabling developers to embed Perplexity-style cited responses into their own applications via a single API call.
Higher-level product that turns a natural-language description of an entity type into a structured, spreadsheet-style dataset of matching results enriched with custom columns — useful for lead generation, recruiting, and market research.
Orchestrates multi-step search, browsing, and synthesis to produce long-form, cited research reports from a single high-level prompt, designed for agentic workflows that need depth rather than a single SERP.
Official Model Context Protocol server plus SDKs and integrations let MCP-aware clients (Claude, Cursor) and frameworks (LangChain, LlamaIndex) call Exa as a native tool without custom adapters.
Supports filtering by domain, date range, language, and content type, with an auto mode that dynamically chooses between neural and keyword search per query for optimal recall and precision.
Prompt builder, API dashboard with usage analytics, status page, and detailed documentation reduce time-to-first-query and make it easier to monitor production deployments.

Exa has continued to expand beyond a pure search API into a broader AI web-data platform. Recent additions include the Websets product for building structured datasets from natural-language descriptions, a Deep Research API for long-form cited reports, and an official MCP server that lets Claude, Cursor, and other Model Context Protocol clients call Exa as a native tool. The Answer endpoint has been hardened for production use with citation support, and the Contents API now offers richer summaries and highlights. Developer tooling has grown with a prompt builder, an updated API dashboard, and additional case studies and integration partners, reflecting Exa's positioning as core retrieval infrastructure for agentic applications.
