Exa (web search)

Connect Exa for AI-powered web search in Agents. Exa is available as a built-in Agent tool, not as a Flow step.

What is Exa?

Exa is a search engine designed for AI Agents. It provides high-quality, relevant web results optimized for semantic understanding.

Setting up Exa

Exa is available through platform keys, so you can use it without providing your own API key. If you want to use your own Exa account:

  1. Sign up at exa.ai
  2. Get your API key
  3. In Runtype, go to Settings → Integrations
  4. Find Exa
  5. Enter your API key
  6. Click Save Key

Using Exa as a tool

Enable the Exa built-in tool when configuring an Agent. The Agent can then autonomously search the web when needed.

The tool accepts:

  • query (required) — Search query
  • searchType — Algorithm: auto (default), neural (semantic), or keyword (traditional)
  • numResults — Number of results to return (1-10, default 5)
  • summary — Include AI-generated summary of each result (default: true)
  • highlights — Include relevant highlights from each result (default: true)
  • text — Include full page text content (default: false)
  • includeDomains / excludeDomains — Restrict or exclude specific domains
  • startPublishedDate / endPublishedDate — Filter by publication date

Use cases

  • Research Agents: Gather current information
  • Fact-checking: Verify claims against web sources
  • Content creation: Find reference material
  • Lead generation: Find companies or contacts
