Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

kling-advanced-lip-sync scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Kling Advanced Lip-Sync

Use this skill for Kling AI Open Platform's documented Advanced Lip-Sync workflow on an existing video. It is distinct from Avatar, which generates a new talking performance from a still image and audio.

Verification and evidence

  • Documented fact: behavior stated in first-party Kling Open Platform pages.
  • Production heuristic: a practical sync/repair recommendation not guaranteed by Kling.
  • Empirical observation: a result measured from an actual task/output.

Facts were verified 2026-07-12. Endpoint visibility, entitlement, pricing, callback behavior, retention, limits, and policy can change. Re-check official documentation, authenticated console, account package, and applicable agreement before paid use.

Official workflow

Base URL in current examples:

https://api-singapore.klingai.com

Operations:

  1. POST /v1/videos/identify-face
  2. POST /v1/videos/advanced-lip-sync
  3. GET /v1/videos/advanced-lip-sync/{id}
  4. GET /v1/videos/advanced-lip-sync

Although the navigation may call a tab Face Recognition, the operation is Identify Face. Describe it as face identification/detection for selecting a visible face; do not claim general identity matching.

Authentication

Official docs use JWT Bearer authentication derived from Kling Open Platform access/secret credentials:

Authorization: Bearer ${KLING_JWT}
Content-Type: application/json

Follow the current authentication page for token construction and lifetime. Generate server-side, use least privilege, and never place keys/secrets/JWTs in browser code, logs, callbacks, or fixtures.

Validate the video source

Identify Face accepts exactly one:

  • video_id: Kling-generated video from the documented recent window;
  • video_url: accessible external video.

They are mutually exclusive.

Current external-video constraints include .mp4 or .mov, 2-60 seconds, at most 100 MB, 720p or 1080p, and width/height each 512-2160 pixels. Current docs also limit Kling video_id recency to 30 days. Kling performs content validation.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
