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 with the inbox_id, the plan ('1h'), a status of 'queued' indicating the renewal is pending payment settlement, and a 'next' field with instructions on how to check the updated inbox status (typically via a GET endpoint). The actual extension applies once the x402 payment settles, usually within a minute.
Example use cases
Support inbox for an agent fleet
“My agent fleet's shared inbox ib_abc123def456 is about to expire — renew it for one more hour using secret 'fleetkey99' and charge the $0.02 in USDC.”
Automated email listener for a workflow bot
“My automation bot needs to keep receiving emails — renew inbox ib_deadbeef0001 with secret 'workflowsecret' for another hour so it doesn't miss any incoming messages.”
One-time verification inbox extension
“I'm waiting on a verification email and my agmail inbox ib_f00dface1234 just ran out — extend it one more hour using secret 'verifyme' so the code arrives before it expires.”
Technical details
Endpoint
POSThttps://agmail.shveik.dev/v1/x402/inbox-1h-renew?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have an existing agmail inbox (identified by an ib_XXXXXXXXXXXX ID) that is about to expire and you need to extend it by exactly one hour using an x402 stablecoin payment. Prefer this over creating a new inbox when continuity of the same inbox address matters (e.g. you are waiting for an email to that specific address). This is the x402 payment variant; if using MPP, use the corresponding MPP sibling endpoint.
Side effects
- Invalid inbox_id format (must match ^ib_[0-9a-f]{12}$) — returns 4xx validation error
- Wrong or missing secret — returns 401 or 403 unauthorized
- Payment not included or insufficient USDC amount — returns 402 Payment Required
- Inbox does not exist or has been permanently expired — returns 404
- x402 payment settlement delay — status remains 'queued' until blockchain confirmation
