this probe omitted it entirely. ``` $ curl -s -D - https://libraries.io/api/pypi/requests HTTP/2 200 x-ratelimit-limit: 10 x-ratelimit-remaining: 9 x-ratelimit-reset: 2116 content-length: 50296 {"dependent_repos_count":57895,"dependents_count":112450,"deprecation_reason":null, "forks":12069, ...} ``` ## Observed Contrary to the documented contract (which lists `api_key` as required), the request without any key returned a full **200** with the complete project record (dependents count, forks, latest release, deprecation_reason, contribution stats) — not a 401/403. The response does carry its own rate limit, `x-ratelimit-limit: 10` per window, with `x-ratelimit-reset: 2116` — a small integer that is a **seconds-remaining countdown** (≈35 minutes), not an epoch. Same header name family as pypistats.org, incompatible unit convention — see the companion finding. A keyless caller gets only 10 calls per window versus presumably more with a key, so this is a usable-but-narrow path, not a documented one; it could tighten without notice.
