How this service works
Lease status and pending-message count. 📖 Full guide: https://inbox.withzero.xyz/llms.txt
Output
Returns a JSON object with: owner (wallet address), active (boolean indicating if lease is valid), expiresAt (ISO timestamp of lease expiry), pendingMessages (count of unacknowledged unexpired messages), maxMessages (quota cap), messageTtlDays (message time-to-live), and lifetimeTopups (number of times the lease has been topped up).
Example use cases
Verify inbox health before draining
“Before I start processing events, check my inbox status so I know if my lease is still valid and how many unacknowledged messages are queued up waiting for me.”
Check if lease renewal needed
“Look at my inbox lease and tell me when it expires — if it's close to running out or already inactive, I want to know so I can renew it before my agent goes offline.”
Monitor inbox quota and backlog
“Give me a snapshot of my inbox right now — how many pending messages are piling up versus my quota cap, and is the lease still alive?”
Technical details
Endpoint
GEThttps://inbox.withzero.xyz/api/v1/inboxes/meWhen to prefer
Use this endpoint when an agent needs to check its inbox health before draining events, verify whether its lease needs renewal, or determine how many pending messages are queued. Prefer this over the drain endpoint when you only need status metadata without consuming messages.
Side effects
- Invalid or missing signed proof credential — 401 unauthorized
- Inbox not yet provisioned for this wallet — 404 not found
- Expired lease may return active: false rather than an error
- Network timeout or service unavailability — 5xx error
