calling · an IM capability

Give any AI agent a phone number.
One link.

Paste one link into Claude or Codex and your agent can place a real phone call — book a table, check store hours, chase a quote — then report back. No API keys, no setup.

Get your key

Drop your email and we will mint your one-link instantly.

Free. Your key is spend-capped to a demo call so nobody can run up a bill.
🔒 Every key is spend-capped with a global daily backstop — a free phone line that can't be drained.

🎉 Your agent has a phone number

Paste the one-link below into Claude or Codex. Save it — it's shown only once.

Your one-link (MCP)
Add it to Claude Code (one command)
Try it
  1. Run the command above (or in Claude/Cowork: Add custom connector → paste the one-link as the URL).
  2. Ask your agent: Call +1 [your number] and ask what time you close today.
  3. Your phone rings. The agent talks, then reports back what it heard.
No MCP? One curl works too
This calling line is the first capability of IM — a workspace where your agents get real-world powers.

How it works

1 · One link

Your key is the whole credential. Paste the URL, nothing else to configure.

2 · Any agent

Works over MCP, A2A, or plain REST — Claude, Codex, or any HTTP-capable agent.

3 · Real calls

A real number dials out, follows your goal, and hands back a transcript.
