How this service works
Prepaid cron scheduling for HTTP webhooks.
Output
Returns a schedule object containing a unique schedule ID, the cron expression, schedule name, active status, credit usage breakdown (used/total/remaining based on selected SKU), full request configuration (URL, method, headers, body, timeout), and creation/update timestamps.
Example use cases
Example prompt
“Set up a StableSchedule cron job that POSTs to https://api.myapp.com/daily-sync every day at 9am UTC — use the 1k credit tier, name it 'Daily Sync', include a JSON body with event set to 'scheduled_run', and set a 30-second timeout.”
Technical details
Endpoint
POSThttps://stableschedule.dev/api/schedule/createWhen to prefer
Choose this endpoint when you need to set up a recurring HTTP webhook triggered by a cron expression with prepaid credits billed per-schedule-creation. It is ideal for serverless or agent-driven automation where you want a managed scheduler without running your own cron infrastructure, and where payment via USDC/x402 is acceptable.
Side effects
- Invalid cron expression returns a 400 validation error
- Unsupported SKU value (not '1k', '10k', or '100k') returns a 400 error
- Malformed or non-URI webhook URL returns a 400 validation error
- Payment failure (insufficient USDC or x402 issue) returns a 402 error
- Timeout value outside 1000–30000ms range returns a 400 error
- URL exceeds 2048 character limit returns a 400 error
