## Probes

```
GET https://www.colorhexa.com/663399.json
GET https://www.colorhexa.com/api/
```

## Observed

`/663399.json` → HTTP 404, `content-type: text/html; charset=utf-8`, body is a bare nginx
error page: `<html><head><title>404 Not Found</title></head><body><center><h1>404 Not
Found</h1></center><hr><center>nginx</center></body></html>`. ColorHexa's human-facing color
pages (`colorhexa.com/663399`) are HTML only; appending `.json` does not switch format, it
just 404s on the underlying nginx/legacy-PHP stack.

`/api/` → HTTP 301 → `Location: https://www.colorhexa.com/api/` (no-op redirect to itself
with a trailing slash added), then HTTP 404 again, but this time `content-type:
application/json; charset=utf-8`, body `{"error":{"code":"not_found","message":"Route not
found"}}`. A guessed non-existent family name under the same path
(`/api/v1/json/families/zzznonexistentfont9999` — no, this is the ColorHexa case; the
equivalent re-probe of `/api/` itself) produces the identical JSON 404 shape, served with
`cf-cache-status: DYNAMIC` and no `x-content-type-options` on the HTML 404 but
`x-content-type-options: nosniff` on the JSON one — two different header fingerprints behind
the same hostname.

The HTML 404 carries no `x-content-type-options` header at all, while the JSON 404 from
`/api/` carries `x-content-type-options: nosniff` — a small but consistent fingerprint
difference between the two backends beyond the content-type itself. Both responses are
Cloudflare-fronted (`server: cloudflare`), so the split is in ColorHexa's own origin
routing, not in Cloudflare's edge behavior.

## Conclusion

`www.colorhexa.com` fronts at least two different backends under the same domain (a legacy
nginx/static one for color pages, a newer JSON-router one for `/api/*`), and **neither one
exposes a working public endpoint** — the documented-sounding `/api/` path itself 404s with
"Route not found", meaning there is no live public ColorHexa API to probe further, only two
different ways of saying "not found."

How observed: 2026-10-05T09:28:14Z and 09:28:33Z, curl GET (one followed the 301
automatically with `-L`), both anonymous.
