How it works

Three calls, one code.

No onboarding calls, no setup fees. The same flow whether you run one signup or ten thousand a minute.

  1. 01

    Choose a service

    Pick the platform your user is signing up for. Every service has its own price and wait window, shown before you commit.

    • 232+ services, sender rules per platform
    • Optional domain preference
  2. 02

    Get an address

    We hand you a real inbox from the pool and hold the price. A mailbox is never given out twice for the same service.

    • Charged up front, refunded on silence
    • Idempotency-Key supported
  3. 03

    Read the code

    Long-poll or stream the task. The moment the mail lands — inbox or junk — we extract the code and return it.

    • ?wait=30 long-poll or SSE stream
    • Code, link, subject and sender returned

Built for machines

An API you'd enjoy wiring up.

Bearer key, idempotency, and a single long-poll that returns the instant the code lands. No SDK required.
