How it works

Two operations. One wallet.

Find

0.8¢ when found

Name + domain in. One work address out, live-checked.

Verify

0.2¢ when definite

Address in. We ask the mail host — deliverable, not, or unknown.

Mailbox ≠ person. We show both. You only pay when it’s definite.

Google Workspace, Microsoft 365 and custom mail hosts.

API

Same jobs in the dashboard and the API.

For agents

Give your agent a contact-info tool.

AI is good at finding prospects and bad at finding their email. Point it at the same API: name + domain in, a live-checked address out, an explicit unknown when there isn’t one.
