The search API that gives AI agents real-time web context
This is our editors' assessment out of 5, not an average of user ratings. The viewpoints on this page are written by AI from what we know about the product. They are not customer reviews.
According to OpenAITools.app telemetry verified on 2026-11-11, Exa (Metaphor Systems) (exa.ai) is an AI platform indexed under AI API generating 0 monthly visits with a month-over-month traffic delta of +0 (0%). Its primary geographic market is Global (— traffic share), and it operates on a Freemium pricing model. Top competing alternatives by monthly volume include Yep.com (155.83K visits/mo), Jina AI (280.78K visits/mo), LangSearch (2K visits/mo).
Switched our entire RAG pipeline from standard Google Custom Search to Exa and the hallucination rate dropped noticeably.
The semantic search capability actually understands what you mean instead of just doing keyword matching.
Free tier is generous enough for prototyping, pricing scales predictably.
Clean API docs.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Low-latency search endpoints (Lite, Auto, Deep) return ranked pages, highlights and structured fields from an independent index covering a large share of the public web.
Retrieve full page text or token-efficient highlights with configurable crawl policies, so models get only the most relevant excerpts rather than whole documents.
Run asynchronous agent runs that navigate, reason and return structured outputs with grounded citations across 70M+ companies and other verticals.
Schedule recurring queries over news, people, companies and financials, and receive updates through webhooks when something changes.
First-party MCP server, Claude Connector and ChatGPT plugin plus SDKs, so Exa slots into existing agent frameworks with minimal glue code.
Metaphor Systems is the earlier name of the company now known as Exa, and the old domain redirects straight to exa.ai. The underlying product is unchanged: a search engine and API that treats the public web as a retrieval layer for AI. Rather than optimising for a human reading ten blue links, Exa optimises for an agent that needs accurate, recent context it can paste into a prompt.
The API spans several products. Search returns ranked results with optional full contents and AI-generated highlights; Contents fetches page text, summaries and metadata; Agent runs longer research tasks asynchronously and returns structured JSON with citations; Monitors watch topics, people or companies on a schedule and fire webhooks. The company also publishes an independent index measured in hundreds of billions of documents and two trillion tracked URLs, and it is a common building block behind coding assistants, chatbots and GTM enrichment workflows.
Exa is developer-first: you sign up, get an API key and call endpoints, with playgrounds and documentation to test queries. Pricing is usage based, and enterprise customers can negotiate custom indexes, data-provider access through Exa Connect, SLAs and zero data retention.
Give chatbots and copilots an up-to-date search tool so responses cite current pages instead of static training data.
Query repos, docs and changelogs at low latency to keep generated code aligned with current package and API references.
Use Monitors and Agent runs to track companies, people and markets on a schedule and receive webhook alerts.
