  title: Kling AI Open Platform Account API
  description: 'The Kling AI Open Platform is the developer API for Kuaishou''s Kling generative video and image models. Every capability follows the same asynchronous pattern: submit a task with POST (receiving a task_id), then poll the matching GET endpoint by task_id until status is succeed and the generated video or image URLs are returned. Generated asset URLs are short-lived and should be downloaded promptly. Authentication uses a JWT (HS256) signed from an Access Key / Secret Key pair, passed as a Bearer token; tokens are short-lived (about 30 minutes).


    endpointsModeled: The overall path structure, async task model, JWT auth, and model catalog are grounded in Kling''s official Open Platform documentation and cross-referenced against multiple Kling API wrappers. Kling''s official reference pages block automated fetching (HTTP 446), so exact request/response field-level schemas here are honestly modeled on the documented behavior rather than copied verbatim, and should be reconciled against the live reference before code generation.'
