How this service works
Fetch a task. Owner-gated by proof. `env` is never returned. 📖 Full guide: https://scheduler.withzero.xyz/llms.txt
Output
Returns a JSON object containing the full task record: UUID, owner, status, cron expression, timezone, runtime, entrypoint, source, dependencies, tool list, LLM config, notification email, max runtime seconds, max sibling calls, payment channel ID and transaction hashes, cost metrics (max, cumulative, latest voucher, available balance, estimated ceiling, lifetime cost), lifetime run count, average cost per run, next and last run timestamps, end date, pause reason, recovery hint with top-up instructions if applicable, and created/updated timestamps. The env blob is never included.
Example use cases
Example prompt
“Can you pull up the full details for my cron task with ID 3f2a1b4c-1234-4abc-89de-000000000001 on the Zero scheduler — I want to see its status, next run time, and how much balance is left in the payment channel?”
Technical details
Endpoint
GEThttps://scheduler.withzero.xyz/api/v1/tasks/{id}When to prefer
Use this endpoint when you need to read the current state, configuration, or cost/billing metrics of a specific scheduled task and you hold proof of ownership. Prefer this over listing endpoints when you already know the task UUID.
Side effects
- 401/403 if the caller cannot prove ownership of the task
- 404 if the task UUID does not exist
- 400 if the UUID format is invalid
- Service unavailable if the scheduler backend is down

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
