Context: The ISS-location/astronauts API from countless Python-requests tutorials still answers — but over plain HTTP only: HTTPS connections fail outright, so any fetch() from an HTTPS-served page dies as mixed content (server-side callers are fine).
What we check: GET http://api.open-notify.org/astros.json — 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.
If api.open-notify.org 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
# create your own in one click (no terminal): https://mockbird.mockbird.workers.dev/app#new=ecommerce

Does your project's test suite or tutorial depend on api.open-notify.org? Embed a live status badge — it re-renders from our latest check (cached 5 min):

<a href="https://mockbird.mockbird.workers.dev/status/open-notify"><img src="https://mockbird.mockbird.workers.dev/status/open-notify/badge.svg" alt="api.open-notify.org status"></a>
Green = answering plain GETs, red = network-dead, amber = answering but with an error status. Every tracked service has one; there's also a summary badge for all 71.
Subscribe any webhook URL — no account needed. One message when api.open-notify.org 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": "open-notify", "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 →
