Argorant Developer Hub
Find and verify contacts, run email campaigns from your own mailboxes and read the replies, from code, the terminal or your AI agent.
Argorant is one workflow behind three surfaces. The REST API is the engine. The CLI (npx argorant) and the MCP server (https://mcp.argorant.com/mcp) are thin layers over the same endpoints, so whatever you build here works for a script, a pipeline or an agent in Claude, ChatGPT or Codex.
Your first call
A key, a free count, a masked preview, a verified export. Ten minutes.
Campaigns end to end
Create the campaign, write the sequence, enroll a list, attach mailboxes, launch.
Replies and the inbox
Read every reply, answer in-thread, set verdicts and your own opportunity stages.
API reference
Every endpoint with parameters, examples and a live playground.
Agents and MCP
Connect Claude, ChatGPT, Codex or your own runtime over OAuth.
CLI
Everything from the terminal, agent-friendly output with --json.

Pricing model, in one line
Counts, previews and lookups are free. One credit is one validated contact; half a credit is one verification of an address you already own. Campaign emails come with your plan and never touch credits. Details on Authentication and limits.
