Poyo Upload And Extend Audio

Use this skill for upload-and-extend-audio jobs on PoYo. It helps agents prepare uploaded-audio extension payloads, choose simple or custom parameters, submit async tasks, and explain callback or music detail retrieval.

Use When

• The user explicitly wants to use PoYo with Upload and Extend Audio, upload-and-extend-audio, audio continuation, music extension, or extending an uploaded song.
• The user asks for a PoYo Upload and Extend Audio request payload, server-side curl command, integration notes, callback setup, or music result retrieval.
• The user has already chosen PoYo as the execution provider for an uploaded-audio extension workflow.

Model Selection

• upload-and-extend-audio: use for extending an uploaded audio file while preserving the source style.

Key Inputs

• upload_url is required and must point to a publicly accessible audio file.
• default_param_flag controls whether the request uses custom parameters.
• instrumental controls whether the extension should omit vocals.
• continue_at controls where the extension starts.
• mv selects the documented music model version.
• prompt, style, and title are used when custom control is needed.
• negative_tags, vocal_gender, style_weight, weirdness_constraint, audio_weight, and persona_id are optional controls when supported by the current PoYo docs.
• 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 log private audio URLs, private lyrics, generated audio URLs, callback URLs, task ids, or raw authorization headers unless the product policy allows it.
• Do not use this skill for generic audio editing unless the user explicitly wants a PoYo Upload and Extend Audio API workflow.
• Do not make live API calls unless the user explicitly asks, confirms the payload should be sent to PoYo, and provides a safe server-side environment.

Execution

• Read references/api.md for endpoint details, request fields, examples, and result retrieval notes.
• Use scripts/submit_upload_and_extend_audio.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 retrieval is easy.

Output Expectations

When helping with Upload and Extend Audio, include:

• chosen model id
• source audio URL handling notes
• simple or custom parameter mode
• continuation timing
• prompt, style, title, and instrumental setting when relevant
• final payload or concise parameter summary
• returned task_id if a request was actually submitted
• next step: query music detail or wait for webhook
