## Probes

```
GET https://api.github.com/repos/nasa/NASA-3D-Resources
GET https://api.github.com/repos/nasa/NASA-3D-Resources/contents/
```

## Observed

Both HTTP 200, `server: github.com`. Repo metadata call: `x-ratelimit-limit: 60`,
`x-ratelimit-remaining: 56`, `x-ratelimit-used: 4` (already partway consumed by the session's
prior calls this lane). Contents listing: `x-ratelimit-remaining: 55`, `x-ratelimit-used: 5` —
confirms each call (repo info, directory listing) decrements the SAME shared 60/hour
unauthenticated bucket keyed to the calling IP, not to the repo. Repo `last-modified:
Sun, 04 Oct 2026` — actively maintained. No dedicated "NASA 3D API" exists; `nasa/NASA-3D-Resources`
is a plain public GitHub repo of OBJ/STL/3DS models for spacecraft and instruments, browsed
exclusively through GitHub's generic repo/contents endpoints.

A third call, listing the `3D Models` subdirectory specifically
(`/contents/3D%20Models`), returned a 227-entry JSON array — one object per model
folder/file at that path — consuming a sixth call against the same budget.

## Conclusion

A client wanting to browse this catalog programmatically is budget-constrained by GitHub's
generic unauthenticated 60/hour limit shared across every other GitHub API call that client
makes in the same hour — not a NASA-specific quota, and invisible as "NASA 3D Resources" rate
limiting unless you already know the resource lives on GitHub. Enumerating even one
subdirectory's 227 entries plus the repo root costs 3 of the 60 hourly calls before a single
model file has been downloaded; walking the full repo tree (many subdirectories, one call
each) would exhaust an unauthenticated budget quickly, whereas GitHub's authenticated REST
budget is 5,000/hour for the identical endpoints — an 83x headroom difference for exactly the
same catalog-browsing task, purely a function of whether the caller sends a token.

How observed: 2026-10-05T10:52:28Z–10:57:59Z, curl GET/HEAD, UA `pwx-scout/1.0`, `--max-filesize 20000000 -m 60`.
