 A cron service calls the trigger endpoint on a schedule to pre-fetch fresh data before you open the dashboard. Without it the app still works — it downloads on demand when you visit — but you wait a few seconds. With it, data is always ready instantly.
 
 - **Service**: any free HTTP cron service (e.g. [cron-job.org](https://cron-job.org), GitHub Actions scheduled workflows, Render cron jobs)
-- **Endpoint**: `<your-host>/api/weather/refresh/trigger?key=<your-key>` (shown in Settings after you generate the key)
+- **Endpoint**: `<your-app-url>/api/weather/refresh/trigger?key=<your-key>` (shown in Settings after you generate the key)
 - **Key management**: generate, rotate, or revoke from **Settings → Automated Weather Refresh** (or set `CRON_TRIGGER_TOKEN` env var)
 - **Rate limit**: 3 requests/minute (separate from the manual refresh limit of 5/min)
 - **Recommended schedule**: once ~10:30 and once ~14:35 local time

 You can pair APD with an automation platform (e.g. [Make.com](https://make.com), [n8n](https://n8n.io), Zapier) to send an email digest after each scheduled refresh:
 
 - **Trigger**: schedule a second HTTP call ~5 minutes after the cron refresh

+- **Content**: fetch the forecast from `<your-app-url>/api/weather/refresh/trigger?key=<your-key>` (shown in Settings after you generate the key)
 - **Smart Email**: construct it from the `astrophotography_score` field to highlight clear nights (simple AI can be very effective here — e.g. "Tonight looks excellent for astrophotography with only 10% cloud cover, while tomorrow is poor with 80% clouds.")
