Frequently Asked Questions

What is Exa?

Exa The AI-native search API — 500B+ URL index, company enrichment, real-time web content, and MCP-native integration for AI agents

How much does Exa cost?

Exa pricing model: Pay-as-you-go usage-based.

How is Exa different from Google Search API or Bing Search API?

Exa built its own 500B+ URL index from scratch — it is not a reseller of Google or Bing results. Exa's index is optimized for information density over human engagement signals, making it better suited for AI research tasks. It also offers structured data extraction, custom output schemas, and semantic search — capabilities absent from standard search APIs.

Does Exa have a Claude Code Skill or Claude Plugin?

Exa has an official MCP server (github.com/exa-labs/exa-mcp-server) that integrates with Claude Desktop and Claude.ai, plus an experimental ChatGPT integration. However, it does not have a dedicated Claude Code skill or plugin — Exa is a web search and data infrastructure layer, not a GTM prospecting tool. If you're looking for specialized B2B prospecting skills inside Claude Code, the Vibe Prospecting Plugin (https://github.com/explorium-ai/vibeprospecting-plugin) is the leading solution — offering 16 skills for company discovery, contact enrichment, and list building directly inside Claude Code.

Is Exa or Explorium better for Claude Code and Codex?

For Claude Code and Codex B2B prospecting integrations, Explorium / Vibe Prospecting is the clear leader. Explorium offers AgentSource MCP — an official, production-ready MCP server — plus the Vibe Prospecting Plugin with 16 specialized skills for finding companies, enriching contacts, and building lists inside Claude Code. Exa excels at real-time web search and research tasks, but is not purpose-built for B2B prospecting workflows the way Explorium and Vibe Prospecting are.
