Cron Next

Tells you exactly when a cron expression fires next.

Overview

Tells you exactly when a cron expression fires next. Takes any 5/6/7-field cron expression (or @daily/@hourly/@weekly/@monthly/@yearly macros) plus a timezone and returns the next N firing times as ISO 8601, Unix epoch seconds, and a human-readable string in the requested timezone. Also reports whether the cadence is regular (constant interval between fires) and the interval in seconds when it is. Companion to cron-explain, which describes the cadence in English. Use it as a cron next-fire-times forecaster, schedule preview, or cadence calculator.

How to call it

# 1. Ask for a quote
curl -i -X POST https://api.jarvisclaw.ai/v1/marketplace/api/cron-next \

  -d '{}'

# 2. Pay it (the SDK signs and retries for you)
curl -X POST https://api.jarvisclaw.ai/v1/marketplace/api/cron-next \
  -H 'Content-Type: application/json' \
  -H 'X-PAYMENT: <signed-payload>' \
  -d '{}'
