Resolve Kwai CDN URL

Extract CDN URLs from Kuaishou share links with two paths:

• videodl (videofetch): primary path, supports cookies/proxy (Playwright + requests).
• GraphQL/mobile-page: fallback when videodl fails.

Path Convention

Canonical install and execution directory: ~/.agents/skills/resolve-kwai-cdn-url/. Run commands from this directory:

cd ~/.agents/skills/resolve-kwai-cdn-url

One-off (safe in scripts/loops from any working directory):

(cd ~/.agents/skills/resolve-kwai-cdn-url && uv run python scripts/kwai_videodl_resolve.py --help)

Fast path (videodl)

uv venv .venv
uv sync
uv run python scripts/kwai_videodl_resolve.py "https://v.kuaishou.com/8qIlZu" > single.jsonl
uv run python scripts/kwai_videodl_resolve.py --input-csv data.csv --csv-url-field URL --output output.jsonl --workers 10
uv run python scripts/kwai_videodl_resolve.py --input-csv data.csv --csv-url-field URL --output output.jsonl --workers 10 --resume
uv run python scripts/kwai_videodl_resolve.py "https://v.kuaishou.com/8qIlZu" --proxy "http://user:pass@host:port"
uv run python scripts/kwai_videodl_resolve.py "https://v.kuaishou.com/8qIlZu" --cookie "<YOUR_COOKIE>"
uv run python scripts/kwai_videodl_resolve.py "https://v.kuaishou.com/8qIlZu" --cookie-file cookie.json

Fallback path (GraphQL/mobile-page)

uv run python scripts/kwai_extract_cdn.py "https://www.kuaishou.com/short-video/3xu6tezif2v55m2" --cookie "<YOUR_COOKIE>"
uv run python scripts/kwai_extract_cdn.py "https://www.kuaishou.com/short-video/3xu6tezif2v55m2" --cookie-file cookie.json
uv run python scripts/kwai_extract_cdn.py "https://www.kuaishou.com/short-video/3xu6tezif2v55m2" --proxy "http://user:pass@host:port"
uv run python scripts/kwai_csv_to_jsonl.py data.csv --url-col URL --cdn-col CDNURL --cookie "<YOUR_COOKIE>" --workers 10 --output output.jsonl
uv run python scripts/kwai_csv_to_jsonl.py data.csv --url-col URL --cdn-col CDNURL --cookie-file cookie.json --workers 10 --output output.jsonl
uv run python scripts/kwai_csv_to_jsonl.py data.csv --url-col URL --cdn-col CDNURL --cookie "<YOUR_COOKIE>" --workers 10 --output output.jsonl --resume
uv run python scripts/kwai_csv_to_jsonl.py data.csv --url-col URL --cdn-col CDNURL --proxy "http://user:pass@host:port" --workers 10 --output output.jsonl

Output

• videodl: {"url": "...", "cdn_url": "...", "error_msg": ""}
• CSV mode (both paths): original columns + CDNURL + optional error_msg

Notes

• videodl auto-extracts the first URL from share text and follows v.kuaishou.com redirects.
• videodl Playwright path honors proxy/cookie/headers passed via requests_overrides in kwai_videodl_resolve.py.
• GraphQL path tries GraphQL, then mobile INIT_STATE, then HTML state parsing.
• If blocked, try without cookies first; if still blocked, pass a real browser cookie via --cookie or --cookie-file.
• --cookie expects a raw Cookie header string, e.g. kpf=PC_WEB; clientid=3; did=....
• --cookie-file accepts either a raw Cookie header string or a JSON cookie array export (list of {name,value} objects).
• When no cookie is provided, videodl will fetch an anonymous cookie from the homepage (incognito-like).
• --proxy applies to all HTTP requests, e.g. http://user:pass@host:port.
• --resume rewrites output JSONL to keep only successful rows, then retries missing/failed rows and appends new results.
• CSV progress logs are batch-based success counts; stats are emitted on completion or Ctrl+C.
• live.kuaishou.com and captcha.zt.kuaishou.com are treated as failures; error_msg includes the reason.
