Context: Community joke API on Google App Engine, big in bootcamp fetch exercises — keyless and read-only. It's a hobby deployment with no uptime commitment.
What we check: GET https://official-joke-api.appspot.com/random_joke — a plain, keyless request from Cloudflare's network with an honest bot UA, exactly what a tutorial curl or an <img> tag experiences. OK = HTTP 2xx/3xx within 8s. No retries, no cookies, no API keys.
Need a tutorial API that answers?
If official-joke-api.appspot.com is failing (or you're tired of finding out mid-demo), Mockbird gives you a seeded, persistent REST API for your tutorial or side project — pick a preset (ecommerce/blog/saas) or import any JSON/CSV as your own dataset; writes persist, CORS on, no signup — free, no signup:
curl https://mockbird.mockbird.workers.dev/m/demo/products/1

Get pinged when it goes down
Subscribe any webhook URL — no account needed. One message when official-joke-api.appspot.com goes down, one when it recovers (debounced: two consecutive hourly checks must agree, so a single blip never fires). Slack and Discord incoming-webhook URLs get a formatted message; anything else gets an HMAC-signed JSON POST.
Or from a terminal / CI script:
curl -X POST https://mockbird.mockbird.workers.dev/api/status/watch \
-H "content-type: application/json" \
-d '{"service": "official-joke-api", "url": "https://hooks.slack.com/services/T000/B000/XXXX"}'Use "service": "*" to watch all 71 tracked services at once. The response includes an unsubscribe curl; 5 consecutive failed deliveries auto-unsubscribe. No webhook? Omit "url" to get a pollable subscription instead — GET the returned poll URL anytime for the transitions since your last poll. Full API details →
The same checker can watch your own URL: POST /api/status/monitor {"url": "https://api.example.com/health", "notify": "<webhook>"} — every 30 minutes, alert on down + recovery, free, no account. Monitor API →
