Cron Create

by gateway.spraay.app in Developer tools

x402 APIPassing, checked 2 min ago

Schedule a recurring trigger: 5-field cron in UTC, at least 1 hour between runs, 100 runs included. On each run the gateway POSTs a signed cron.triggered webhook to your https callback_url; your agent then calls batch/execute or payroll/execute itself and pays for it as usual. Actions: batch.execute, payroll.execute, webhook.trigger.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.1.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://gateway.spraay.app/api/v1/cron/create' \
  -H 'content-type: application/json' \
  --data-raw '{"action":"batch.execute","callback_url":"https://agent.example.com/spraay/cron","maxRuns":52,"payload":{"amounts":["1000000"],"recipients":["0x..."],"token":"USDC"},"schedule":"0 9 * * 1"}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
