Everything for Disposable Email

Four clean REST endpoints — create, receive, read, and delete.

Create Inbox

Generate a random or custom disposable email address instantly via API.

Get Messages

Poll the inbox for incoming messages. Returns full metadata list.

Read Message

Read full HTML or plain-text body. Perfect for OTP/verification code extraction.

Delete Inbox

Clean up early. Deletion is free — no credits charged.

24h Lifetime

Inboxes stay alive for 24 hours then auto-expire and self-clean.

Secure Tokens

Each inbox has a private token — only the holder can read its messages.

# 1. Create a disposable inbox
curl -X POST /api/tempmail/accounts \
  -H "X-API-Key: your_key"
# → {"email":"abc123@zphantom.com","token":"tok_xxx"}
# 2. Check for messages
curl /api/tempmail/messages \
  -H "X-API-Key: your_key"
# → {"messages": [{"id":"msg_1","subject":"Your OTP","from":"..."}]}
