Executes web searches across a 70M+ company-indexed proprietary web crawl with four configurable latency profiles (instant <180ms, fast ~450ms, auto ~1s, deep 5-60s). Uses a custom ranking system optimized for AI query patterns rather than traditional SEO signals, returning results as JSON with URLs, titles, and snippets. The ranking model appears trained on relevance to LLM-based downstream tasks rather than human click-through data.
Unique: Implements four distinct latency profiles (instant/fast/auto/deep) with explicit speed-quality tradeoffs, optimized for AI agent integration rather than human search UX. Ranking algorithm trained on LLM relevance patterns rather than traditional SEO signals, enabling faster convergence on AI-useful results.
vs alternatives: Faster than Perplexity/Brave for agent-integrated search (180ms instant mode vs. typical 1-3s round-trip) and claims 54.4% accuracy on FRAMES benchmark vs. Perplexity's 54.2%, with superior performance on Tip-of-Tongue (44.5% vs 36.7%) and Seal0 (21.6% vs 19.3%) retrieval tasks.
Executes iterative, multi-step web research workflows that decompose complex queries into sub-queries, retrieve results for each step, and synthesize findings into structured JSON outputs. Uses an internal reasoning loop (likely LLM-based chain-of-thought) to determine follow-up searches and extract entities/relationships from results. Outputs are schema-flexible JSON suitable for downstream processing without additional parsing.
Unique: Implements internal multi-step reasoning loop that iteratively refines searches based on intermediate results, then extracts and structures findings into JSON without requiring pre-defined schemas. Reasoning process is opaque to user but optimized for complex research tasks that would require 3-5 manual search iterations.
vs alternatives: Automates multi-step research workflows that competitors (Perplexity, Brave) require manual query refinement for, and outputs structured JSON directly suitable for agent consumption vs. unstructured prose answers.
Allows search queries to be constrained by domain whitelist (search only specified domains) or blacklist (exclude specified domains), and by content type (e.g., exclude news, focus on documentation). Filtering is applied server-side during ranking, reducing irrelevant results before returning to client. Enables focused searches (e.g., 'search only GitHub and Stack Overflow' or 'exclude news and social media').
Unique: Applies domain and content-type filtering server-side during ranking, reducing irrelevant results before returning to client. Enables focused searches without post-processing filtering.
vs alternatives: More efficient than client-side filtering (reduces data transfer and processing); server-side filtering ensures ranking is aware of constraints, improving result quality vs. post-hoc filtering.
Maintains a continuously-updated web index with configurable crawl frequency for different content types. News and frequently-updated content are crawled more frequently; static documentation less frequently. Enables searches to return recently-published content (e.g., news articles, blog posts) without waiting for manual re-indexing. Crawl freshness is not user-configurable but varies by content type and source authority.
Unique: Maintains continuously-updated web index with content-type-specific crawl frequencies, enabling searches to return recently-published content without manual re-indexing. Crawl policies are optimized for AI agent use cases (frequent updates for news/blogs, less frequent for static docs).
vs alternatives: More current than static search indexes (Google's index may be weeks old for some content); crawl frequency is optimized for AI agents rather than human search UX.
Provides dedicated search indexes optimized for specific content verticals: code (GitHub, Stack Overflow, documentation), people (professional profiles, bios), companies (structured company data with fields like founding year, CEO, funding), news (news-specific ranking), and general web. Each vertical uses domain-specific ranking signals and structured metadata extraction tailored to that content type. Queries can specify a vertical via type parameter to constrain search scope.
Unique: Maintains separate, domain-optimized indexes for code, people, companies, and news rather than a single general-purpose index. Each vertical uses ranking signals specific to that domain (e.g., GitHub stars for code, professional network signals for people, company registration data for companies) enabling higher precision than general web search.
vs alternatives: Provides dedicated code search comparable to GitHub's native search but integrated into a single API, and company/people search with structured output that general search engines (Google, Bing) do not offer natively.
Retrieves full HTML/text content of web pages indexed by Exa and optionally generates token-efficient highlights (key excerpts) that summarize page content without requiring full page processing by downstream LLMs. Highlights are pre-computed during indexing and returned as a separate field, reducing token consumption for LLM processing. Full contents are returned as raw text suitable for RAG pipelines or LLM context windows.
Unique: Pre-computes and caches token-efficient highlights during indexing, allowing downstream LLMs to consume summarized content without full-page processing. Highlights are returned as a separate field, enabling cost-conscious applications to choose between full content and summaries on a per-page basis.
vs alternatives: More efficient than fetching raw HTML and processing with LLMs (saves tokens and latency) and cheaper than calling separate summarization APIs; highlights are pre-computed rather than generated on-demand, reducing per-request latency.
Sets up persistent monitors that track changes to specified web pages or search queries at configurable intervals (daily, weekly, or custom). When changes are detected, returns new/updated content matching the monitor criteria. Internally maintains a state machine tracking page versions and diffs, triggering notifications when content changes exceed a threshold. Useful for tracking competitor websites, news about specific topics, or monitoring for new research publications.
Unique: Maintains persistent query monitors with state tracking across multiple check intervals, returning only new/changed results rather than full result sets. Enables long-running monitoring workflows without requiring external scheduling infrastructure or database state management.
vs alternatives: Simpler than building custom monitoring with external schedulers and state stores; integrated into Exa API so no separate infrastructure needed. Cheaper than running continuous crawlers for specific URLs.
Generates natural language answers to queries by first retrieving relevant web content via search, then using an internal LLM to synthesize answers grounded in retrieved sources. Supports streaming responses for progressive answer delivery. Internally chains search → retrieval → LLM generation, with optional citation of source URLs. Answers are streamed token-by-token, enabling real-time display in user interfaces.
Unique: Integrates search, retrieval, and LLM-based answer generation into a single streaming API endpoint, eliminating the need for application developers to orchestrate multiple API calls. Streaming responses enable progressive answer delivery without waiting for full synthesis.
vs alternatives: Simpler than building custom search + LLM chains with LangChain/LlamaIndex; single API call vs. multiple orchestrated calls. Streaming support enables better UX than non-streaming alternatives (Perplexity, Brave) in real-time interfaces.
