# WithZero Scheduler Enqueue Task (Deprecated)

> WithZero Scheduler Enqueue Task (Deprecated) is a paid API for AI agents from agents.withzero.xyz, paid per call via MPP, price unknown, status unknown (last checked 2026-09-12).

Asynchronously triggers an immediate run of a scheduled task by pulling its next_run_at forward to now — deprecated alias for POST /tasks/:id/trigger

## Facts

- Endpoint: POST https://agents.withzero.xyz/api/v1/scheduler/tasks/{id}/enqueue
- Price: price unknown
- Payment: MPP
- Status: unknown
- Last checked: 2026-09-12
- Activations on Zero: 0
- Provider: agents.withzero.xyz
- Website: https://agents.withzero.xyz
- Canonical page: https://www.zero.xyz/c/agents-withzero-xyz-withzero-scheduler-enqueue-task-deprecated-471d3910
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_3eacVYe7Wbj-xU7ejyI-o

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agents-withzero-xyz-withzero-scheduler-enqueue-task-deprecated-471d3910 -d '<json body>'
```

Example prompt: Kick off my scheduled task with ID a3f2c1d0-1234-4b56-89ab-fedcba987654 right now — don't wait for the result, just trigger it immediately.

## When to prefer this

Use this endpoint only if migrating from older code — new implementations should call POST /tasks/:id/trigger instead, which is the canonical non-deprecated replacement. Both endpoints behave identically: they trigger an async, non-blocking immediate run of a task and return without waiting for execution. Choose this over synchronous run endpoints (POST /tasks/:id/runs) when you do not need to wait for the task result and want fire-and-forget dispatch within ~1 minute.

## Known failure modes

- Task ID not found or not owned by caller — returns 404
- Task is not active — returns success with enqueued: false (no-op, not an error)
- Invalid UUID format for task ID — returns 400 validation error
- Authentication/payment failure — returns 402 or 401
- Server error during scheduling state update — returns 500

## 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 task_id (UUID), status string, next_run_at (ISO timestamp or null), and enqueued boolean — true if the task's next run was successfully advanced to now, false if the task was inactive (safe no-op). The response arrives immediately without waiting for the task execution to complete.
