How this service works
Receive-only email inboxes for AI agents, by the hour. Pay in stablecoins with x402 or MPP; one call returns the code or the link.
Output
Returns a JSON object containing: the plan name ('1h' or similar), a secret token for polling or authenticating inbox access, the assigned email address (e.g. acme42@agmail…), the message capacity (e.g. 50), a unique inbox ID, and an expiry timestamp indicating when the inbox will be deactivated.
Example use cases
Agent email verification flow
“My agent needs to sign up for a service that sends a confirmation email — can you create a temporary agmail inbox called 'verifybot01' so it can receive that email in the next 4 hours?”
Disposable inbox for automated testing
“I'm running an automated test that expects an email to arrive — spin up a 4-hour agmail inbox named 'testrun99' so the test can check for incoming messages.”
Support inbox for an agent fleet
“One of my agents needs a short-lived email address to receive a password reset link — provision a 4-hour agmail inbox called 'resetagent7' and give me the address and secret.”
Technical details
Endpoint
POSThttps://agmail.shveik.dev/v1/mpp/inbox-4h?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs a real, receive-only email address for a short 4-hour window — ideal for catching verification emails, password resets, or confirmations during automated workflows. Prefer it over longer-duration plans when cost matters and the task completes within hours. Use it over generic email APIs when you need pay-per-use stablecoin billing with no account setup.
