WithZero Scheduler: Async Task Trigger
WithZero Scheduler: Async Task Trigger is a paid API for AI agents from agents.withzero.xyz, paid per call via MPP, price unknown, status unknown (last checked 2026-09-15).
Asynchronously triggers a scheduled task by pulling its next run forward to now, returning immediately without waiting for execution.

How this service works
Trigger a run asynchronously (non-blocking): pulls next_run_at to now; the dispatch tick runs it within ~1 min. Returns immediately. No-op on non-active tasks. Use POST /tasks/:id/runs for a synchronous run. 📖 Full guide: https://scheduler.withzero.xyz/llms.txt
Output
Returns a JSON object with the task's UUID, a status string, the updated next_run_at timestamp (or null), and an 'enqueued' boolean indicating whether the task was actually advanced (true if active and triggered, false if the task was not active and the call was a no-op).
Example use cases
On-demand data pipeline kickoff
“My nightly data ingestion task is ID b2e4a1d3-9c8f-4321-bcde-012345678901 — can you trigger it right now without waiting for it to complete? I just need it kicked off immediately.”
Early newsletter dispatch
“The weekly newsletter task is scheduled for tonight but I want to send it now — the task ID is f7a0c5e2-1b3d-4890-aabc-fedcba987654. Trigger it asynchronously so I don't have to wait.”
Unblocking a stalled background job
“My background cleanup job (task ID d9b3f1a2-7e5c-4012-cdef-abcdef123456) seems stuck waiting for its next scheduled run — can you push it to run now and just return immediately?”
Technical details
Endpoint
POSThttps://agents.withzero.xyz/api/v1/scheduler/tasks/{id}/triggerWhen to prefer
Use this endpoint when you want to trigger a task immediately but do NOT need to wait for execution to complete — ideal for fire-and-forget scenarios, avoiding blocking an agent thread, or when the task may take a long time. If you need the run result synchronously, use POST /tasks/:id/runs instead. If the task may or may not be active, this is still safe to call (no-op on inactive tasks).
Side effects
- Task not found — invalid or unknown UUID returns a 404
- Task is not active — returns 200 with enqueued: false (safe no-op)
- Unauthorized — missing or invalid ownership proof returns 401/403
- Malformed task ID in path — returns 400 validation error
- Scheduler service unavailable — returns 5xx
