Music Generation Models Integration Skill

> Use this skill to explore and integrate all available Music Generation models through the ShortAPI platform.

Overview

ShortAPI provides a unified /api/v1/job/create endpoint for music generation natively. This skill provides an overview of all available music generation models and how to dynamically acquire the specific JSON schema required to invoke them.

• API Endpoint: https://api.shortapi.ai/api/v1/job/create
• Category: text-to-audio
• Kind: inference

Available Music Models

Here is the list of fully supported music generation model IDs you can use:

How to use a Music Model

Because each music model supports different parameters (such as lyrics, genre, style, duration, instrumental, or advanced controls), you need to fetch the specific model's schema document to construct a valid API request payload.

Step 1: Fetch the specific Model API Skill Document (MANDATORY)

You MUST first fetch the detailed skill document for the specific (e.g. suno/suno-v5/generate) before attempting to construct the POST request payload. DO NOT skip this step. DO NOT hallucinate parameters because different models have completely different parameter names and supported features.

Send a GET request to:

https://shortapi.ai/api/skill/<model_id>

_(For example: GET https://shortapi.ai/api/skill/suno/suno-v5/generate)_

This URL will return a Markdown (.md) text document containing the exact Input Parameters Schema for that specific model, alongside code examples. You must parse it to understand which arguments go into the args object.

Step 2: Construct the JSON Payload

Using the exact schema document fetched from Step 1, construct a valid JSON payload. Only include arguments that were defined in the document fetched in Step 1.

At a minimum, standard structures generally look like this:

{
  "model": "<model_id>",
  "args": {
    "prompt": "Your music description or lyrics here..."
    // ...other model-specific required or optional parameters strictly parsed from Step 1
  },
  "callback_url": "YOUR_OPTIONAL_WEBHOOK_URL"
}

Step 3: Invoke the Unified Generation Endpoint

Make an HTTP POST request to the API Endpoint. Include the Bearer token in the Authorization header.

Bash (cURL) Example

response=$(curl --request POST \
  --url https://api.shortapi.ai/api/v1/job/create \
  --header "Authorization: Bearer $SHORTAPI_KEY" \
  --header "Content-Type: application/json" \
  --data '{
    "model": "suno/suno-v5/generate",
    "args": {
      "prompt": "A upbeat electronic dance track with catchy synth melodies"
    }
  }')
JOB_ID=$(echo "$response" | grep -o '"job_id": *"[^"]*"' | sed 's/"job_id": *//; s/"//g')

Step 4: Fetch Generation Status (Background Polling)

Use the returned job_id to poll the query API:

curl --request GET \
  --url "https://api.shortapi.ai/api/v1/job/query?id=$JOB_ID" \
  --header "Authorization: Bearer $SHORTAPI_KEY"

Security, Privacy & Safety Disclosure

• Endpoint Isolation: This skill only communicates with https://api.shortapi.ai.
• Credential Safety: The SHORTAPI_KEY is only used in the Authorization header to the official API endpoint and must never be included in any callback payload or exposed to third parties.
• Background Polling Policy: To ensure resource safety, the Agent should poll the status endpoint for a maximum of 5 minutes per job. If a job does not complete within this window, the Agent must inform the user and stop polling.
• State Management: The Agent stores job_id and polling state exclusively within the current conversation context. No persistent external database is used for tracking job states by this skill.
• Content Sanitization: Before rendering generated results (audio, images, or video) inline, the Agent MUST verify that the URLs point to authorized shortapi.ai or known CDN domains. The Agent is responsible for ensuring that the embedded HTML tags (, , ) do not contain malicious attributes or scripts.
• Callback Lockdown: The callback_url parameter is strictly user-defined. The Agent is prohibited from auto-generating or hallucinating this value.

CRITICAL BEHAVIOR FOR AGENTS:

1. Authentication First (SHORTAPI_KEY): Before any other step, you MUST verify if the user has a SHORTAPI_KEY. If it is missing, you MUST proactively direct the user to https://shortapi.ai to obtain their API key. DO NOT ask for or accept any other type of API key (e.g., OpenAI, Anthropic, etc.); the only valid key is the SHORTAPI_KEY from ShortAPI.ai.
2. Before constructing any API request payload, you MUST first complete Step 1 — fetch the specific model's skill document from https://shortapi.ai/api/skill/. DO NOT skip this step. DO NOT guess or hallucinate parameters. The document returned in Step 1 is the sole source of truth for the model's input schema.
3. Music generation takes time. Once you receive the job_id from Step 3, you MUST immediately inform the user that the task has started and release them so they can ask other questions or start new conversations.
4. You MUST continue to poll the status endpoint in the background silently.
5. Once the polling returns a completed state (status: "succeeded"), you must proactively message the user with the final generation results (e.g., displaying the generated audio URLs returned in the response payload).
6. When presenting results, you MUST not only provide the raw URL but also render the content inline for direct preview in the chat. For audio/music, use an HTML tag to embed an inline audio player. For images, use markdown image syntax !description. For videos, use an HTML tag. The user should be able to see and play the generated result immediately without needing to open a separate browser tab.
