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 inbox email address, a secret token for authenticating inbox reads, a unique inbox ID, the plan duration (4h), the maximum message cap, and an expiry timestamp indicating when the inbox will be destroyed.
Example use cases
Agent verification email capture
“Create a 4-hour agmail inbox named 'verifybot99' so my agent can receive a verification code from a third-party signup flow.”
Support inbox for an agent fleet
“Spin up a temporary email inbox called 'support42' for 4 hours so my agent fleet can receive incoming support messages during a test run.”
Webhook notification receiver
“I need a short-lived receive-only inbox named 'notifyme01' to catch notification emails from an external service for the next few hours.”
Technical details
Endpoint
POSThttps://agmail.shveik.dev/v1/x402/inbox-4h?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs a 4-hour temporary receive-only email inbox and you want to pay via stablecoin (USDC) using x402 or MPP. Prefer this over longer-duration plans when the task is short-lived (e.g. a single verification flow or brief integration test). Prefer agmail generally over traditional temp-mail services when your workflow is crypto-native or requires programmatic payment without API keys.
Side effects
- Invalid inbox name (fails regex pattern or length constraint) — returns 400 with validation error
- Payment failure or insufficient USDC balance — returns 402 with payment required details
- Name already taken — returns 409 conflict
- Service unavailable or rate limit exceeded — returns 503 or 429
