Copilot
GrokNative support across Claude, ChatGPT, Gemini, GitHub Copilot, and Grok Build
Everything you need for contact search, out of the box.
No scrapers, no manual contact hunting, no extra infrastructure.
Native MCP tool
The agent calls search_leads right inside the conversation — no separate UI, no copy-pasting.
Live business data
Business contacts from public sources. Field availability and accuracy depend on the source — for email, we show the result and the method's limitations.
Web dashboard & billing
API keys, usage stats, and remaining balance in a single personal dashboard.
A small REST API
The same search is available over HTTP — for integrations without an MCP client.
Email Finder included
We scrape the company's own website for a contact email — included in every plan, no per-lookup charge. Sites Cloudflare blocks are flagged, not silently skipped.
Multi-platform

From search to billing — fully transparent.
Discovery, enrichment, and billing run as a single pipeline.
