For developers, Clay users, and AI agents
Pay per result, not per seat
Agents run thousands of lookups. You pay a credit when we return data and nothing when we don't.
Safe for autonomous spending
Per-key daily caps, per-call ceilings, and read-only keys keep an agent from spending more than you planned.
Fewer bounces
Every email runs through a validation waterfall and comes back with a risk grade from A to D.
- 01
Create a key
Sign up and copy an API key. Free accounts get 100 credits a month.
- 02
Connect your tool
Add the MCP server to Claude, Cursor, or any MCP client, or call the REST API from your code, Clay, or n8n.
- 03
Set a spend cap
Pick a daily credit limit for each key. When an agent hits it, calls stop until the next day.

See plansIs it really unlimited?
No, and we think you should be wary of anyone who says so. Every plan includes a set number of credits, with overage at a published rate, so you always know what a job will cost.
Where does the data come from?
Licensed data partners, consent-aware publisher networks, and our own verification. We do not scrape LinkedIn.
What about phone calls and texts?
You're responsible for TCPA compliance when you call or text a mobile number, including checking the Do Not Call registry. Our numbers come with line-type data to help.
