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:
Sign up at exa.ai
Get your API key
In Runtype, go to Settings → Integrations
Find Exa
Enter your API key
Click Save
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
Next steps
