Quick Start

Terminal

npm install && npm start  # http://localhost:4400

Endpoints

bash

# Explain a cron expression in plain English
curl http://localhost:4400/api/v1/explain/*/5%20*%20*%20*%20*
# → "at minutes 0, 5, 10, ..., of every hour"

# Validate
curl http://localhost:4400/api/v1/validate/0%209%20*%20*%201-5

# Next 5 run times
curl "http://localhost:4400/api/v1/next/0%209%20*%20*%20*?count=5"

# Generate cron from description
curl -X POST http://localhost:4400/api/v1/generate \
