Enqueue Task for Immediate Execution (Non-Blocking)
Enqueue Task for Immediate Execution (Non-Blocking) is a paid API for AI agents from scheduler.withzero.xyz, paid per call via MPP, metered — billed by usage, status unknown (last checked 2026-09-14).
Pulls a scheduled task's next run forward to now so the dispatch tick executes it within ~1 minute, without blocking the caller.

How this service works
DEPRECATED — use POST /tasks/:id/trigger. Behaves identically (async, non-blocking). 📖 Full guide: https://scheduler.withzero.xyz/llms.txt
Output
Returns a JSON object with the task's UUID, current status string, the updated next_run_at timestamp (or null), and an 'enqueued' boolean indicating whether the run was actually pulled forward (true) or the task was inactive and this was a no-op (false).
Example use cases
Example prompt
“A webhook just came in — go ahead and enqueue task 3f2a1b4c-0000-0000-0000-000000000001 to run within the next minute without waiting for it to finish.”
Technical details
Endpoint
POSThttps://scheduler.withzero.xyz/api/v1/tasks/{id}/enqueueWhen to prefer
Use this endpoint when you need to trigger a task run immediately from an event-driven context (e.g. webhook handler) and do not need to wait for the result. It is ideal for burst event coalescing since multiple calls within the same dispatch tick window collapse into a single run. Prefer this over POST /tasks/:id/runs when you want non-blocking fire-and-forget semantics. For synchronous execution where you need the final run status returned immediately, use the synchronous runs endpoint instead.
Side effects
- Task ID not found — 404 not found
- Task is paused or in terminal state — returns enqueued: false (safe no-op, not an error)
- Invalid UUID format — 400 bad request
- Unauthorized caller — 401/403 if ownership proof missing
- Scheduler service unavailable — 5xx error
