Exa

Exa uses pay-as-you-go pricing with a free tier that includes roughly 1,000 requests per month. Beyond the free tier, pricing is metered per request type: keyword search is billed at a lower per-1,000-request rate than neural search, and full-page content retrieval is priced separately per 1,000 pages. Enterprise plans with custom rate limits are available on request, so confirm current rates on the official pricing page.

You send a query to the API and Exa returns relevant results using neural, semantic search against a real-time web index. You can then use the Contents endpoint to pull clean full-page text or token-efficient highlights for feeding into an LLM. For more complex needs, the Deep and Agent products run multi-step research and return structured output based on a schema you define.

Exa is an API-first product, so you sign up for an account, get an API key from the dashboard, and call the endpoints from your application code. There is an API playground for experimenting with search, agent, and content requests before you integrate. No infrastructure setup is required since it is a hosted service.

Because Exa is delivered as a REST-style API, it integrates with virtually any language or framework and slots into RAG pipelines, agent frameworks, and LLM applications. It powers search inside developer and productivity tools such as Cursor, HubSpot, and Monday.com. Exa Connect also provides access to leading external data providers.

Exa offers a zero data retention option and enterprise-grade security controls aimed at teams embedding search into production products. This makes it suitable for security-conscious organizations that need assurances about how request data is stored and handled. Verify the specific terms and any compliance certifications with Exa directly for your deployment.

Exa has expanded from a search API into a broader platform, adding Deep research, Agent, and Monitors products alongside the core Search and Contents endpoints. It also launched Exa Connect for accessing leading third-party data providers. The company has continued to update its pricing and real-time capabilities for chat apps, voice AI, and coding agents.

Yes, Exa offers a free tier that includes up to 1,000 requests per month. This free plan provides access to web search tool calls for agents, webpage text and highlights, and configurable latency options from 180ms to 1 second. Beyond the free tier, Exa operates on usage-based pricing.

Exa is used by major platforms including Cursor, Cognition, HubSpot, OpenRouter, and Monday.com, serving over 400,000 developers. As an API-first service, it can integrate with any application that can make HTTP requests. Specific integration details for other platforms were not found in our research — check the official documentation for comprehensive integration guides.

Exa is positioned as an AI-native search API with neural search capabilities, competing with alternatives like Tavily, Firecrawl, and traditional search APIs. Reviewers note that Exa excels at semantic search and contextual understanding for LLM applications. However, alternatives like Tavily may offer more predictable costs and faster response times in some cases, while tools like Firecrawl provide deeper structured data extraction. The choice depends on whether you prioritize semantic search quality, cost predictability, or extraction depth.
