YouTube Data API videos.insert 返回隐藏的“每天上传的视频数”429，尽管配额空间仍然充足

Summary Starting around May 24-25, 2026, uploads through the YouTube Data API videos.insert endpoint began failing after a small number of uploads per day with HTTP 429: json { "error": { "code": 429, "message": "Quota exceeded for quota metric 'Video Uploads' and limit 'Video Uploads per day' of service 'youtube.googleapis.com' for consumer 'project_number:REDACTED'.", "errors": [ { "message": "Quota exceeded for quota metric 'Video Uploads' and limit 'Video Uploads per day' of service 'youtube.googleapis.com' for consumer 'project_number:REDACTED'.", "domain": "global", "reason": "rateLimitExceeded" } ] } } This appears to be a hidden or newly enforced quota separate from the documented YouTube Data API quota-unit system. ## Expected behavior According to the YouTube Data API quota documentation: * Default project quota is 10,000 units/day * videos.insert costs 100 units * Quota resets at midnight Pacific Time A default project should therefore support roughly 100 uploads/day, assuming no other significant quota usage. If there is a separate Video Uploads per day quota, it should be documented and visible in Cloud Console / Cloud Quotas API so developers can monitor it and request increases. ## Actual behavior Uploads fail after roughly 7 uploads/day with: > Quota exceeded for quota metric 'Video Uploads' and limit 'Video Uploads per day' However: * Cloud Console shows YouTube Data API quota usage well below 100% * gcloud beta quotas info list --service=youtube.googleapis.com does not expose a Video Uploads per day metric * Cloud Quotas API also does not appear to expose this metric * Manual uploads through YouTube Studio to the same channel still work ## Environment * API: YouTube Data API v3 * Method: videos.insert * Library: google-api-Python-client * Version tested: 2.196.0 * Upload type: resumable upload * Auth scope: https://www.googleapis.com/auth/youtube.upload * Project has YouTube Data API enabled * OAuth app, project, and channel are unchanged from before the regression ## Minimal code shape media = MediaFileUpload(path, chunksize=-1, resumable=True) request = youtube.videos().insert( part="snippet,status", body={ "snippet": { "title": title, "description": description, }, "status": { "privacyStatus": "private", }, }, media_body=media, ) response = None while response is None: status, response = request.next_chunk() ## Additional evidence Multiple developers appear to be reporting the same behavior in the same timeframe: API uploads fail after a small number of videos, while Cloud Console still shows quota headroom and manual YouTube Studio uploads still work.
