Know who's real before they cost you.

One API that tells you if a contact is real, and tells your AI agent exactly what to do about it: accept, ask the user, or reject. Emails, phone numbers, IPs and domains on one key: typos, disposable inboxes, dead domains, VoIP numbers, Tor and bot traffic caught in one call.

AI agents

Your agent knows what to do next

Every answer carries agent_action and plain-English reasons it can read back to the user. Hosted MCP server, OpenAPI, and llms.txt so Claude, ChatGPT, Cursor, n8n and LangGraph agents plug in in one line. Agents can even sign up for a key themselves.

Questions

How is this different from 1Lookup, ZeroBounce or NeverBounce?

Email and phone on one balance, cheaper per lookup at every tier, and answers designed for agents to act on, not just humans to read.

Do you send emails or texts to check?

No. Nothing is ever sent to the contact. We check the address and number against carrier metadata and DNS.

Do you store my data?

Lookups are processed in memory and not kept. We keep only usage counts for billing. See privacy.
