notes: >-
  Kuaishou publishes throttling as ERROR CODES rather than as a rate-limit reference page, and returns
  no rate-limit response headers on any surface probed. That is the finding: an integrator can learn
  that they were throttled only by parsing the body, and cannot learn their remaining budget at all.
  Two concrete numeric limits ARE published, both for local-services product mounting. Everything else
  is undocumented.
limit_count: 2
signal_headers:
  published: []
  observed: []
  note: >-
    No X-RateLimit-*, RateLimit-* or Retry-After header was returned by any Kuaishou, Kwai or Kling host.
    The only correlation headers present are X-REQUEST-ID and X-KSLOGID on open.kuaishou.com. On Kling
    AI the correlation value is carried in the response body as request_id, not in a header.

      The provider states the limits verbatim: "当前限制：商品挂载10min 1次，商品编辑10s 1次". Limits for the same
      product under different POIs are independent of one another.

  note: >-
    No rate-limit documentation is reachable on the public surface; developers.kwai.com is a JavaScript
    single-page application and its reference is gated behind advertiser registration.
- api: kuaishou:kling-ai
  limits: []
  concurrency_note: >-
    Kling AI is an asynchronous generation API — work is submitted, then polled by generationId — so the
    meaningful constraint is concurrent-task and credit budget rather than requests per second. Neither
    a published concurrency table nor a rate-limit header was found. The provider's MCP/CLI guide does
    publish one hard constraint on the agent surface: MCP and CLI accept only PAID credits from the
    Personal workspace, and bonus credits cannot be spent through them.

gaps:
- >-
  No numeric request-rate limit is published for the Kuaishou Open API generally, for the Kwai for
  Business marketing API, or for the Kling AI generation API.
- >-
  No rate-limit response headers are emitted anywhere, so an agent cannot read remaining budget or a
  reset time from a live response — it can only detect the throttle after the fact from result code
  10000302 or 10002032.
