Use this skill for Kling 2.1 image-to-video jobs on PoYo. It helps agents prepare Standard and Pro payloads, submit async tasks, and explain polling or webhook follow-up.

Use When

• The user explicitly mentions Kling 2.1, kling-2.1/standard, kling-2.1/pro, or PoYo Kling 2.1 video generation.
• The task is start-frame image-to-video or Pro start/end-frame video generation.
• The workflow needs PoYo async task submission, task status polling, or callback URL guidance.

Model Selection

• kling-2.1/standard: use for start-frame guided image-to-video.
• kling-2.1/pro: use for start-frame guided image-to-video with optional end-frame guidance.

Key Inputs

• prompt is required inside input.
• start_image_url is required for both Standard and Pro.
• duration can be 5 or 10.
• end_image_url is optional and only supported by kling-2.1/pro.
• negative_prompt is optional for excluding unwanted visual traits.
• callback_url is optional and useful for production queues.

Security Rules

• Treat POYO_API_KEY as a secret.
• Keep PoYo API keys in server-side environment variables or a backend secret manager.
• Never place an API key in browser code, frontend bundles, public repositories, logs, screenshots, or chat output.
• Do not make live API calls unless the user explicitly asks and provides a safe server-side environment.
• Do not submit confidential prompts, private source images, private end-frame images, private callback URLs, or generated media URLs unless the user trusts PoYo and the callback receiver.

Execution

• Read references/api.md for endpoint details, model ids, common fields, example payloads, and polling notes.
• Use scripts/submit_kling_2_1.sh only when the user wants to submit a prepared JSON payload from a trusted shell.
• If the user only needs a curl example, adapt one from references/api.md.
• After submission, report the returned task_id clearly so follow-up polling is easy.

Output Expectations

When helping with Kling 2.1, include:

• chosen model id
• whether Standard or Pro is selected
• final payload or concise parameter summary
• selected duration and negative prompt when relevant
• whether an end frame is involved
• returned task_id if a request was actually submitted
• next step: poll status or wait for webhook
