Exa Connect

Exa Connect plugs premium data partners directly into the Exa Agent loop. Attach a provider to a run and the Exa Agent queries that partner’s database the same way it searches the web, then blends both into one grounded, structured answer. New to agent runs? Start with the Exa Agent guide, then come back to attach data partners.

Prefer MCP? Exa Agent and Exa Connect are available in Exa MCP. Enable tools=agent_tools to run multi-step research, list-building, enrichment, and structured output from Claude, Cursor, and other MCP clients.

Why Exa Connect

Premium data, no integrations. Reach premium partner data without signing contracts or wiring up an SDK. You call one Exa API.
Exa handles the plumbing. We manage provider authentication, tool selection, retries, and result ranking. The Exa Agent does the rest.
Exa Agent picks the right source. When your outputSchema asks for “monthly visits from Similarweb” or “verified officers,” the Exa Agent calls the matching partner tool instead of guessing from a web page.
Web + partners in one run. Connect doesn’t replace Exa web search; it composes with it. The Exa Agent uses each source where it’s strongest and cites everything.

How it works

Attach one or more providers via the dataSources array on POST /agent/runs.
The Exa Agent selects the right tool for each step based on your query and outputSchema: partner data or Exa web search.
Partner results are fused with web research into your structured output, with sources attached.

Pricing

Exa Connect pricing is additive with standard Agent run pricing. You pay the usual Agent compute and search costs, plus the provider call charge for each Exa Connect tool call.

Usage

Combining providers

Attach as many partners as your task needs — the Exa Agent calls each one where it’s strongest and blends the results with web search into a single structured answer:

{
  "dataSources": [
    { "provider": "similarweb" },
    { "provider": "fiber" },
    { "provider": "harmonic" }
  ]
}
