Argorant Developer Hub
A complete B2B outreach platform your code or your AI agent can run from start to finish. Find people, get checked emails and phone numbers, run campaigns and answer replies.
Argorant does the whole outreach job in one place, and every step is an API call.
Find the companies and people that fit your offer among 626.5M+ contacts in 202 countries. Get their work emails, checked right before you receive them, and their phone numbers. Find one person's email from a name and a company domain. Check the emails on lists you already have. Write a campaign with a personal line for every contact, send it from your own Google Workspace or Microsoft 365 mailboxes or from new mailboxes we set up on new domains for you, and answer the replies in the same thread.
You can do all of it from code, from the terminal, or by asking an AI agent such as Claude, ChatGPT or Codex. The REST API, the command line tool npx argorant and the MCP server https://mcp.argorant.com/mcp share one account, one credit balance and the same rules.

What it costs
Argorant is the cheapest way to get validated B2B contacts. With pay as you go, 100,000 credits cost $499, which is under half a cent per validated contact. On Hyperscale, 200,000 credits a month cost $649, about a third of a cent each. An email that fails the check costs nothing. Compare the prices yourself on our comparison pages and the alternatives, for example Argorant and ZoomInfo, Cognism, Hunter, LeadIQ, Prospeo, Seamless or UpLead side by side.
