FAQ
Q: How do I get my own API Key? A: Go to redfox.hk to register and get a Token.
Q: Do the downloaded videos have watermarks? A: No. The API returns direct links to watermark-free videos.
Q: Will multiple resources be returned? A: Yes. The API usually returns multiple resources, which may include video files and audio files in different formats (such as mp4, webm, m4a, etc.). The download link for each resource will be fully listed, so you can choose as needed.
Q: Can I upload multiple links in bulk? A: No. You can only enter one link at a time; bulk uploads will cause parsing to fail.
Q: What should I do if the link shows a parsing failure? A: Confirm whether the link is complete, whether the video still exists, and whether it is region-restricted content. Deleted or restricted videos cannot be parsed.
