Claude Code, Codex and Cursor can now order Inbox Insiders mailboxes for you. One line sets it up, and your agent asks before every order.
If you already work in Claude Code, Codex or Cursor, you can now order mailboxes without opening the order form. Tell your agent "order 25 Hyperboxes for acme-outreach.com" and it handles the rest.
Setup takes one line. Open the API page, pick your agent, copy the line and paste it into a terminal. That installs our skill, which teaches the agent how ordering works. Then create an API key under Settings and save it as INBOX_INSIDERS_API_KEY, so your agent can use it without you pasting it into the chat. Using a different agent? The Any agent tab gives you one sentence to paste instead.
Your agent orders with the card saved on your account. Before each order it tells you how many mailboxes, which type and the total, and it waits for your yes.
