How this service works
Stop a task. Direct rail closes the payment channel and refunds remaining escrow. ZeroClick rail releases pending reservations and reports no refund because buyer billing is held by the marketplace. 📖 Full guide: https://scheduler.withzero.xyz/llms.txt
Output
Returns a JSON object with the task ID, updated status, billing rail (direct or zeroclick), a channel close transaction hash (or null for ZeroClick), the amount in micros claimed by the seller, and the amount in micros refunded to the buyer.
Example use cases
Cancel runaway recurring job
“Cancel the WithZero scheduled task 9e4d2c1a-7b3f-4e5a-8c6d-0f1a2b3c4d5e — it's been running longer than expected and I want to get the remaining escrow back.”
Stop completed data pipeline task
“The data pipeline task I set up on WithZero is done early — go ahead and stop task ab12cd34-ef56-7890-abcd-ef1234567890 so the payment channel closes and unused funds are refunded.”
Terminate ZeroClick marketplace task
“I need to stop my ZeroClick task 11223344-5566-7788-99aa-bbccddeeff00 on WithZero and release the pending reservations.”
Technical details
Endpoint
DELETEhttps://agents.withzero.xyz/api/v1/scheduler/tasks/{id}When to prefer
Use this endpoint when you need to explicitly stop a task you previously created via the WithZero scheduler and want to trigger payment settlement — either to close a direct payment channel and reclaim unused escrow, or to release ZeroClick marketplace reservations. Prefer this over simply abandoning a task when cost recovery or clean resource cleanup matters.
Side effects
- Task ID not found — 404 with error indicating no matching task
- Unauthorized access — task is owner-gated and caller lacks proof
- Task already stopped or in terminal state — may return 409 or idempotent response
- Invalid UUID format for task ID — 400 validation error
- Payment channel closure failure on-chain — may return 500 or partial state
