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 being renewed, the plan name ('24h'), a status of 'queued' indicating the extension will be applied once payment settles (typically within a minute), and a 'next' field with instructions on how to check the updated inbox status via a GET endpoint.
Example use cases
Keep agent inbox alive overnight
“My AI agent's agmail inbox ib_0123456789ab is about to expire — renew it for another 24 hours using MPP so it keeps receiving emails through the night.”
Automated daily inbox renewal
“Every morning, renew my agmail inbox ib_0123456789ab for another 24-hour plan using the MPP payment route — here's my secret for authentication.”
Support inbox for an agent fleet
“I have a receive-only agmail inbox ib_0123456789ab that my customer-support agent uses — extend it 24 more hours via MPP so it doesn't miss any incoming messages today.”
Technical details
Endpoint
POSThttps://agmail.shveik.dev/v1/mpp/inbox-24h-renew?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extend an already-created agmail inbox for another 24 hours using the MPP (Micropayment Protocol) payment method with stablecoins. Choose this over the x402 renew variant when your agent infrastructure is integrated with MPP rather than x402. Prefer this over creating a new inbox when you want to maintain continuity of the same inbox_id and email address for your agent.
Side effects
- Invalid inbox_id format (must match ^ib_[0-9a-f]{12}$) — request rejected
- Wrong or missing secret — authentication failure
- Payment settlement failure or insufficient USDC balance — renewal not applied
- Inbox not found or already expired — renewal cannot be queued
- MPP protocol error — payment channel unavailable
