ZenVault Pull-Based Work Queue

Choose this endpoint when you need a durable, pull-based work queue where multiple agent workers independently claim tasks and lease timeouts protect against lost work from crashes or hangs. It is especially appropriate for distributed agent workflows running on ZenVault's infrastructure, where sibling services (key-value storage, webhook buffering, run-state resumption) are also in use. Prefer it over a simple message queue when automatic lease expiry and requeue semantics are required — i.e., when you cannot guarantee that every worker will acknowledge completion.

• Invalid or missing lease timeout configuration returns a 400 error
• Duplicate queue name conflict if queue already exists
• Payment failure via x402 protocol blocks queue creation
• Management token lost if not captured at creation — cannot be re-retrieved
• Queue not found if management token is used after queue expiry or deletion
