LNemail

Setup and use anonymous email accounts on LNemail.net using Bitcoin Lightning payments. Use when agents need email capabilities for 2FA, notifications, or co...

Anonymous email accounts via Lightning Network. No KYC, no email required to sign up—just pay with Bitcoin.

Overview

LNemail provides fully functional email addresses for 1000 sats/year. Perfect for agents needing:

• 2FA code reception
• Anonymous communication
• Bitcoin/Lightning service notifications
• API-accessible email without identity requirements

Quick Start

1. Create Email Account

Create a Lightning invoice for email account creation:

# Create the account (returns payment hash)
curl -X POST https://lnemail.net/api/v1/email

# Response:
# {
#   "payment_hash": "abc123...",
#   "amount": 1000,
#   "currency": "SATS"
# }

2. Pay with Lightning

# Get the invoice from payment status endpoint
curl -X GET https://lnemail.net/api/v1/payment/PAYMENT_HASH

# Response when pending:
# {
#   "payment_hash": "abc123...",
#   "status": "pending",
#   "lightning_invoice": "lnbc10u1pj..."
# }

Pay the BOLT11 lightning_invoice using any Bitcoin Lightning Network wallet (e.g., Alby CLI).

3. Retrieve Credentials

After payment confirms (~seconds), check status again:

curl -X GET https://lnemail.net/api/v1/payment/PAYMENT_HASH

# Response when paid:
# {
#   "payment_hash": "abc123...",
#   "status": "paid",
#   "email": "[e-mail]",
#   "access_token": "eyJhbG..."
# }

Save these credentials! Store them securely (e.g., ~/.lnemail/credentials.json).

Using Your Email

Check Inbox

curl -X GET https://lnemail.net/api/v1/emails \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN"

# Response:
# [
#   {
#     "id": "msg_123",
#     "from": "[e-mail]",
#     "subject": "Your 2FA Code",
#     "received_at": "2024-01-15T10:30:00Z",
#     "has_attachments": false
#   }
# ]

Read Email Content

curl -X GET https://lnemail.net/api/v1/emails/EMAIL_ID \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN"

# Response:
# {
#   "id": "msg_123",
#   "from": "[e-mail]",
#   "to": "[e-mail]",
#   "subject": "Your 2FA Code",
#   "body": "Your verification code is: 123456",
#   "received_at": "2024-01-15T10:30:00Z"
# }

Note: HTML content is stripped for security; emails are plain text only.

Send Email

Sending requires a Lightning payment (~100 sats per email):

# Create send request
curl -X POST https://lnemail.net/api/v1/email/send \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -d '{
    "recipient": "[e-mail]",
    "subject": "Hello",
    "body": "Message content here"
  }'

# Response:
# {
#   "payment_hash": "def456...",
#   "amount": 100,
#   "currency": "SATS"
# }

Pay the invoice, then check status:

curl -X GET https://lnemail.net/api/v1/email/send/status/PAYMENT_HASH

# Response when paid:
# {
#   "payment_hash": "def456...",
#   "status": "paid",
#   "message_id": "msg_sent_789"
# }

API Reference

Endpoint	Method	Auth	Description
/email	POST	No	Create account (returns payment hash)
/payment/{hash}	GET	No	Check account payment status
/emails	GET	Bearer	List inbox messages
/emails/{id}	GET	Bearer	Get message content
/email/send	POST	Bearer	Create send request (returns payment hash)

Storage Recommendation

Store credentials in ~/.lnemail/credentials.json:

{
  "email": "[e-mail]",
  "access_token": "eyJhbG..."
}

Note: The access_token is the only credential needed for ongoing operations. The payment_hash is only used during initial setup to check payment status — once you have the access_token, it can be discarded.
