Cronlytic

Use Cronlytic via direct curl calls to schedule and manage cron jobs that trigger HTTP requests/webhooks.

Official docs: https://www.cronlytic.com/api-documentation

When to Use

Use this skill when you need to:

Schedule recurring HTTP requests (webhooks, API calls) Automate background tasks without managing servers Create cron jobs with standard 5-field expressions Pause/resume jobs dynamically Monitor job execution via logs Prerequisites Sign up at Cronlytic Go to Dashboard → API Keys → Generate New API Key Copy your API Key and User ID export CRONLYTIC_API_KEY="your-api-key" export CRONLYTIC_USER_ID="your-user-id"

Base URL https://api.cronlytic.com/prog/

Important: When using $VAR in a command that pipes to another command, wrap the command containing $VAR in bash -c '...'. Due to a Claude Code bug, environment variables are silently cleared when pipes are used directly.

bash -c 'curl -s "https://api.example.com" -H "Authorization: Bearer $API_KEY"' | jq .

How to Use 1. Health Check (Ping)

Check if API is available (no auth required):

bash -c 'curl -s -X GET "https://api.cronlytic.com/prog/ping"'

Response: {"message": "pong"}

Create a Cron Job

Create a scheduled job to call a webhook.

Write to /tmp/cronlytic_request.json:

{ "name": "daily-backup", "url": "https://api.example.com/backup", "method": "POST", "headers": {"Authorization": "Bearer token123"}, "body": "{\"type\": \"full\"}", "cron_expression": "0 2 * * *" }

Then run:

bash -c 'curl -s -X POST "https://api.cronlytic.com/prog/jobs" -H "X-API-Key: ${CRONLYTIC_API_KEY}" -H "X-User-ID: ${CRONLYTIC_USER_ID}" -H "Content-Type: application/json" -d @/tmp/cronlytic_request.json' | jq '{job_id, name, status, next_run_at}'

Create GET Request Job

Simple health check every 5 minutes.

Write to /tmp/cronlytic_request.json:

{ "name": "health-check", "url": "https://api.example.com/health", "method": "GET", "headers": {}, "body": "", "cron_expression": "/5 * * * " }

Then run:

List All Jobs

Get all your scheduled jobs:

bash -c 'curl -s -X GET "https://api.cronlytic.com/prog/jobs" -H "X-API-Key: ${CRONLYTIC_API_KEY}" -H "X-User-ID: ${CRONLYTIC_USER_ID}"' | jq '.[] | {job_id, name, status, cron_expression, next_run_at}'

Update a Job

Then run:

bash -c 'curl -s -X PUT "https://api.cronlytic.com/prog/jobs/" -H "X-API-Key: ${CRONLYTIC_API_KEY}" -H "X-User-ID: ${CRONLYTIC_USER_ID}" -H "Content-Type: application/json" -d @/tmp/cronlytic_request.json' | jq '{job_id, name, status, next_run_at}'

Pause a Job

Stop a job from executing. Replace with the actual job ID:

bash -c 'curl -s -X POST "https://api.cronlytic.com/prog/jobs//pause" -H "X-API-Key: ${CRONLYTIC_API_KEY}" -H "X-User-ID: ${CRONLYTIC_USER_ID}"'

Resume a Job

bash -c 'curl -s -X POST "https://api.cronlytic.com/prog/jobs//resume" -H "X-API-Key: ${CRONLYTIC_API_KEY}" -H "X-User-ID: ${CRONLYTIC_USER_ID}"'

Get Job Logs

View execution history (last 50 entries). Replace with the actual job ID:

bash -c 'curl -s -X GET "https://api.cronlytic.com/prog/jobs//logs" -H "X-API-Key: ${CRONLYTIC_API_KEY}" -H "X-User-ID: ${CRONLYTIC_USER_ID}"' | jq '.logs[] | {timestamp, status, response_code, response_time}'

Delete a Job

Permanently delete a job and its logs. Replace with the actual job ID:

bash -c 'curl -s -X DELETE "https://api.cronlytic.com/prog/jobs/" -H "X-API-Key: ${CRONLYTIC_API_KEY}" -H "X-User-ID: ${CRONLYTIC_USER_ID}"'
