Is Numbers API (numbersapi.com) down?

FAILING right now — answering HTTP 404 to plain requests.

Last checked 2026-09-11T19:30:45Z · checked every hour · OK-rate 24h: 0% · 7d: 0% · raw JSON · Atom feed of its down/recovered events

Failing streak began 2026-08-31T15:30:00Z or earlier (11 days — dead, not a blip) · last successful check: none in the last 7 days

Context: The number-trivia API behind a decade of fact-of-the-day tutorials is gone — every fact URL answers a bare nginx 404, and the domain's TLS certificate now belongs to an unrelated site. It never had official HTTPS, so the http:// URLs in tutorials also break as mixed content when called from an HTTPS page.

What we check: GET http://numbersapi.com/42 — 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 numbersapi.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
# create your own in one click (no terminal): https://mockbird.mockbird.workers.dev/app#new=ecommerce

Read the honest Numbers API (numbersapi.com) migration guide → (it also says when Numbers API (numbersapi.com) is the better tool) or create your own mock API in one click.

README badge

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

<!-- Markdown -->
[![numbersapi.com status](https://mockbird.mockbird.workers.dev/status/numbersapi/badge.svg)](https://mockbird.mockbird.workers.dev/status/numbersapi)

<!-- HTML -->
<a href="https://mockbird.mockbird.workers.dev/status/numbersapi"><img src="https://mockbird.mockbird.workers.dev/status/numbersapi/badge.svg" alt="numbersapi.com 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.

Get pinged when it goes down

Subscribe any webhook URL — no account needed. One message when numbersapi.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": "numbersapi", "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 →
