Exa AI

What is Exa AI?

Exa is a powerful search API designed specifically for AI agents that require real-time web data, deep research capabilities, and structured content from a single endpoint. It combines search, crawling, and research functionalities into one seamless interface, enabling developers to build agents that can access and process web information efficiently.

Key features include lightning-fast search with best-in-class accuracy across all verticals, including FRAMES, Tip-of-Tongue, and Seal0 benchmarks. Exa offers smart token-efficient search, which is ideal for coding agents that need to retrieve relevant context from documentation and repositories without wasting tokens. The API also provides highlights—concise excerpts extracted by a specialized model that passes up to 25 trillion tokens to models weekly, ensuring agents get the most relevant information.

Exa supports structured outputs with enrichments across over 70 million companies, making it suitable for business research, competitive analysis, and data enrichment tasks. Users can configure the API for fast results or deep research with grounded citations, ensuring reliability and traceability.

Use cases include powering AI research assistants, coding agents, financial analysis tools, and any application that needs up-to-date web data. For example, agents can use Exa to find recent funding rounds (like Silverflow's $40m Series B or Embat's €30m Series B) or track aerospace industry news about companies like Boeing.

Technical details: Exa is a RESTful API with simple authentication via API keys. It supports JSON responses and can be integrated into any programming language. The API offers endpoints for search, crawling, and extraction, with parameters to control result count, freshness, and content type. Pricing is usage-based, with a free tier for experimentation and scalable plans for production use.

Exa is built for developers who need reliable, real-time web data for their AI agents, combining speed, accuracy, and structured outputs in one API.
