Tsinghua Rate Limits

Tsinghua University publishes no rate-limit documentation of any kind, and none of its three publicly reachable machine-readable endpoints returned a rate-limit header, a Retry-After, or a 429 in a full probe pass on 2026-08-19. The one throttle-shaped behaviour observed is not a rate limit at all: the TUNA mirror edge answers HTTP 403 with an HTML denial page to requests carrying a desktop-browser User-Agent, while answering the identical request 200 for a plain tool User-Agent. Callers should still harvest politely — the mirror is a shared community resource and the ISO catalog response alone is 461KB.
