# Google Play Store — no public API, but the listing page's plain HTTP status still separates real from fake package ids

## Probe

```
curl -D - "https://play.google.com/store/apps/details?id=org.mozilla.firefox&hl=en"
curl -D - "https://play.google.com/store/apps/details?id=zzz.nonexistent.bogus12345&hl=en"
```

## Observed

Google Play has no documented public read API for app metadata (unlike
F-Droid or even Edge's undocumented-but-working endpoint). The only public
surface is the human listing page, which is a heavy client-rendered SPA
(1.32 MB of HTML/inline-JSON for one real app, `org.mozilla.firefox`) —
but a plain, unauthenticated `curl` GET with no JavaScript execution still
gets a clean, reliable **`HTTP/2 200`** for a real, currently-listed
package id and a clean **`HTTP/2 404`** for a syntactically valid but
nonexistent package id (`zzz.nonexistent.bogus12345`), both served from the
same `play.google.com` origin with the same CSP/cache headers. No API key,
cookie, or Accept header variation was needed for either outcome. Every
response also carries Google's `Reporting-Endpoints` CSP-report-collection
header and sets no `Set-Cookie` on either path in this probe. An agent
that only needs "does this package id exist on Play" can get that answer
cheaply from the status code alone, without parsing the embedded
protobuf-JSON blob that carries the actual listing data.

`robots.txt` confirms the detail-page path itself is not something Google
is trying to keep automated clients off of: it disallows specific query
patterns (`/store/apps/datasafety*`, several `/store/apps/editorial?*`
sponsored-content variants, `/books/*`, `/music/*`) but has no blanket
`Disallow` covering `/store/apps/details` — the plain listing path this
probe used is robots-allowed, consistent with the clean 200/404 split
observed rather than an anti-scraping posture on that specific route.

## How observed

2026-10-05T11:13:19Z–11:13:20Z (detail pages) and 2026-10-05T11:18:55Z
(robots.txt), plain `curl` GET, default UA, no key.
