Create a Lumbox Inbox

Use this skill when an AI agent needs a real, working email address - for example, to sign up for a third-party service, receive an OTP, or communicate with humans.

When to use

Agent needs to sign up for a SaaS that requires email verification
Agent needs to receive an OTP or magic link
Each workflow/session needs an isolated inbox (no cross-contamination)

Prerequisites

A Lumbox API key. Create one at https://app.lumbox.co/settings/api-keys.
Set the key in the LUMBOX_API_KEY environment variable.

Steps

Call the API with POST https://api.lumbox.co/v1/inboxes:

curl -X POST https://api.lumbox.co/v1/inboxes \
  -H "X-API-Key: $LUMBOX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name": "github-signup-bot"}'

Read the response. Extract address (the real email address) and id (the inbox identifier):

{
  "id": "inb_8x2f9a...",
  "address": "[email protected]",
  "imap_password": "..."
}

Use the address. Provide address as the email during sign-up or anywhere an email is needed. Emails sent to this address arrive in the inbox within seconds.

Tips

Use descriptive names (name) so you can find the inbox later in the dashboard.
To receive email at a custom domain (e.g. [email protected]), configure the domain first via POST /v1/domains.
Free tier: 3 inboxes, 500 emails/month. Upgrade at https://lumbox.co/pricing.
