# APKMirror and APKPure — both fully Cloudflare-managed-challenge gated for a non-browser client

## Probe

```
curl -D - "https://www.apkmirror.com/apk/mozilla/firefox/"
curl -D - "https://www.apkmirror.com/wp-json/"
curl -D - "https://apkpure.com/firefox-browser-fast-private/org.mozilla.firefox"
```

## Observed

All three requests — a real APKMirror app page, a guessed WordPress REST
discovery path (`/wp-json/`) on the same host, and a real APKPure app
page — return the identical shape: `HTTP/2 403`, `server: cloudflare`,
`cf-mitigated: challenge`, and a small (5.3–5.5 KB) interactive-challenge
HTML page naming `challenges.cloudflare.com` in its CSP (`script-src
'nonce-…' 'unsafe-eval' https://challenges.cloudflare.com`). The block
fires before any application logic runs — the WordPress REST discovery
probe (which on an un-protected WordPress site would normally return a
namespace list, real or 404) gets the exact same challenge page as the
real content page, byte-for-byte shape (only the per-request CSP nonce and
`content-length` differ by a few bytes). `critical-ch`/`accept-ch` request
Client-Hint headers the probe's plain `curl` never supplies, which is
consistent with this being bot-fingerprinting, not path-specific access
control: a non-browser client gets the same wall regardless of which URL
on either host it asks for, so a 403 from either site is evidence about
the client, not about whether the requested page/path exists.

The challenge is specifically a dynamic-page mitigation, not a whole-domain
block: `robots.txt` on both `www.apkmirror.com` and `apkpure.com` — a
static file Cloudflare can usually serve from edge cache without invoking
the managed-challenge rule — returns a clean `HTTP 200` on both hosts with
no challenge page at all. So the gate is applied per-route (app pages and
guessed API paths) rather than being an unconditional reject of any
non-browser client hitting the domain; a scraper could, in principle, read
`robots.txt` to confirm the host is reachable before concluding the real
content paths are unreachable for an unrelated reason.

## How observed

2026-10-05T11:13:26Z–11:13:27Z (challenge probes) and 2026-10-05T11:18:55Z–
11:18:56Z (robots.txt contrast), plain `curl` GET, default UA, no key.
