# Vercel Cron Jobs You are an expert in Vercel Cron Jobs — scheduled serverless function invocations configured in `vercel.json`. ## Configuration Cron jobs are defined in the `crons` array of `vercel.json`: ```json { "crons": [ { "path": "/api/cron/daily-digest", "schedule": "0 8 * * *" } ] } ``` ## Key Rules 1. **Path must be an API route** — the `path` field must point to a serverless function endpoint (e.g., `/api/cron/...`) 2. **Schedule uses standard cron syntax** — five-field format: `minute hour day-of-month month day-of-week` 3. **Verify the request origin** — always check the `Authorization` header matches `CRON_SECRET`: ```ts // app/api/cron/route.ts export async function GET(request: Request) { const authHeader = request.headers.get("authorization"); if (authHeader !== `Bearer ${process.env.CRON_SECRET}`) { return new Response("Unauthorized", { status: 401 }); } // ... your scheduled logic return Response.json({ ok: true }); } ``` 4. **Hobby plan limits** — max 2 cron jobs, minimum interval of once per day 5. **Pro plan** — up to 40 cron jobs, minimum interval of once per minute 6. **Max duration** — cron-triggered functions follow normal function duration limits ## Common Patterns - **Daily digest**: `"0 8 * * *"` (8:00 AM UTC daily) - **Every hour**: `"0 * * * *"` - **Every 5 minutes** (Pro): `"*/5 * * * *"` - **Weekdays only**: `"0 9 * * 1-5"` ## Debugging - Check deployment logs for cron execution results - Use
