lumbox

Email for AI agents. Create inboxes, receive OTPs, extract verification codes — all via API.

Install

pip install lumbox

Quick Start

from lumbox import Lumbox

client = Lumbox(api_key="ak_...")

# Create an inbox
inbox = client.create_inbox(name="github-bot")
# → github-bot@lumbox.co

# Sign up on any service with inbox.address...

# Wait for the OTP (blocks until it arrives)
otp = inbox.wait_for_otp(timeout=60)
print(otp["code"])  # "847291"

Auth header

The SDK sends Authorization: Bearer ak_... by default. The legacy X-API-Key header still works server-side. Raw HTTP example:

curl https://api.lumbox.co/v1/inboxes \
  -H "Authorization: Bearer ak_your_key_here"

Inbox-scoped API keys

Mint a key that can only ever touch one inbox:

created = client.inboxes.api_keys.create(inbox.id, name="ci-bot")
print(created["api_key"])  # shown once

client.inboxes.api_keys.list(inbox.id)
client.inboxes.api_keys.delete(inbox.id, created["id"])

Features

• OTP extraction — verification codes parsed automatically
• Long-poll — wait_for_email() and wait_for_otp() block until arrival
• Send/reply/forward — full outbound email support
• Custom domains — DKIM, SPF, DMARC verification
• LangChain & CrewAI — pre-built tool wrappers

Framework Integration

Any Framework
