StableSchedule

Prepaid cron scheduling for HTTP webhooks. Register a schedule with a cron expression, destination URL, method, headers, and body. Each trigger spends one run credit; exhausted schedules pause until you top up.

Install StableSchedule into AgentCash, register a first cron schedule, and keep webhook scheduling available for reuse.

How it works

1. POST /api/schedule/create with a SKU, cron expression, and request to register a schedule.
2. StableSchedule triggers your destination URL on schedule, spending one run credit per trigger.
3. Pause, resume, top up, or delete a schedule, and inspect run history at any time.
