Welcome
Humans
& Agents.

// THE PROBLEM

Why are you managing
10 API keys?

GTM engineers and AI agents deserve better than duct-taping a dozen providers together. We fixed that.

♟
Clay locks you in

Clay is a walled garden. Your data lives in their table, not yours. No portability, no flexibility, no escape.

⚡
10 keys, 10 bills

Hunter, Apollo, Clearbit, ZoomInfo — each with their own auth, their own pricing, their own headaches.

◈
Agents can't discover

Your agent can't autonomously find, evaluate, and call data sources. There's no MCP layer. Until now.

// THE STORE

Every data API.
One key.

1st party data we built. 3rd party data we curated. All accessible through a single endpoint.

// HOW IT WORKS

Four steps.
Infinite data.

01
Get one key

Sign up free. One API key unlocks every data source in the store. No separate accounts.

02
Browse the store

Discover 1st and 3rd party APIs. Read reviews from real GTM engineers. See pricing upfront.

03
Call or connect MCP

Use REST or plug our MCP server into your agent. It discovers and calls endpoints autonomously.

04
One bill, done

Usage across every provider, consolidated into a single monthly invoice. No surprises.

// THE DIFFERENCE

Not another walled garden.

The old way (Clay, etc.)
Your data lives in their table, not yours
Proprietary credits and opaque pricing
No MCP — agents can't use it natively
Locked into one UI, one workflow
You pay for the platform, not the data
AgentDataMart
Your data, your database, your pipeline
Usage-based pricing, one transparent bill
Native MCP — agents discover and call autonomously
Clean JSON back, pipe it anywhere
Pay per call, only for what you use
