How it works

Three calls, one code.

No onboarding call, no setup fee, no minimum spend. The same flow whether you run one signup a day or ten thousand a minute.

01

Create the task

POST /v1/tasks with a service slug. We hand you a real mailbox from our pool and hold the price — never the same address twice for the same service.

02

Trigger the signup

Use the address on the platform. Only mail that arrives after the task was created counts, so an older code is never handed to a new task.

03

Read the code

One long-poll (?wait=30) or an SSE stream returns the moment the mail lands — inbox or junk. We extract the code and the link for you.

Catalog

Questions

Before you sign up.

What happens if no code arrives?

The task times out when its window closes and the held amount returns to your balance automatically. You are never charged for silence.

Are these real mailboxes?

Yes — Hotmail and Outlook addresses from a pool we own and refill ourselves, not disposable domains that platforms block at signup.

How long is the window?

5 minutes today, set per service and returned as ttl_sec. You can ask for a different one per task, clamped to 60–900 seconds.

Can I reuse an address?

Yes, with /again on the same task: a new task pinned to that mailbox, minutes or weeks later, as long as we keep the task (180 days) and its mailbox is active. Lost the task id? GET /v1/tasks?email= finds it. It is free when you start it within 10 minutes of the last charged code on that address for the same service (not for Other) — so the second email a platform sends costs nothing; after that it is charged again. An address is closed only for the services where it already received a code.

Is there a rate limit?

No requests-per-second limit. What is capped is failure: more than 500 failed calls in one minute pause the account for a while. Successful calls never count.

How do I pay?

Crypto top-ups from $1. The balance is a plain USD wallet; every charge and refund is listed on your Wallet page.
