## Probes

```
GET https://api.sketchfab.com/v3/search?type=models&q=chair&downloadable=true&count=24
GET https://api.sketchfab.com/v3/search?type=models&q=chair&count=50
```

## Observed

Both HTTP 200, `server: gunicorn`, fully keyless (no Authorization header sent, none
required). `count=24`: 24 results, `next` cursor link exactly `...&count=24&cursor=24...`.
`count=50`: **still exactly 24 results** (`len(results) == 24`), and the returned `next` link
silently rewrites the requested `count=50` down to `count=24` (`...&count=24&cursor=24...`,
also dropping the `downloadable=true` filter from the `next` URL in this case since it wasn't
set on the second call) — Sketchfab does not clamp the number it returns to the number you'll
see by comparing requested vs. returned count alone; you have to notice the `next` link's
rewritten `count` param to realize the cap was applied silently rather than honoring 50.

A third probe, following the `next` cursor from the first page (`cursor=48` with `count=24`),
still returns exactly 24 results and a correctly-populated `previous` link back to `cursor=24`
— the 24-item cap is strictly per-page, not a total-result ceiling; pagination past page 1
works normally, it just never returns more than 24 rows in any single response regardless of
what `count` asks for. No `Authorization` header, no API key, and no rate-limit header of any
kind appeared on any of the three calls — the entire search surface for downloadable models is
open to an anonymous client, the per-page cap aside.

## Conclusion

A client that only checks `len(results)` against its own `count` request would wrongly
conclude the dataset simply had 24 total matches when `count=50` was requested; the `next`
pagination link is the only place the actual server-side cap (24) surfaces explicitly, and a
client must follow `next`/`previous` cursors rather than requesting a larger page to retrieve
more than 24 downloadable models per call.
