> ## Agent Instructions
> Phaseo Gateway base URL: https://api.phaseo.app/v1. Send `Authorization: Bearer $PHASEO_API_KEY` with every request.
> Model IDs look like `provider/model`, for example `openai/gpt-6-astra`. Do not guess IDs: list them with `GET /v1/models` or check https://phaseo.app/models. `phaseo/free` routes to an available free model and needs no wallet balance.
> For new text integrations prefer `POST /v1/responses`. `POST /v1/chat/completions` (OpenAI format) and `POST /v1/messages` (Anthropic format) suit existing code.
> The full API contract is https://phaseo.app/docs/openapi/v1/openapi.yaml. Official SDKs: `@phaseo/sdk` (TypeScript) and `phaseo` (Python), plus Go, C#, PHP, Ruby and Rust.
> Search these docs over MCP at https://phaseo.app/docs/mcp, and install Phaseo skills with `npx skills add https://phaseo.app/docs`. If a page is wrong or out of date, report it with the MCP `submit_feedback` tool.
> Manage Phaseo accounts with the `phaseo` CLI (`npm install -g @phaseo/cli`, then `phaseo login` or `phaseo login --device-code`), the `/v1` Management API or the MCP server at `https://mcp.phaseo.app/mcp?access=manage`. Do not send users to the dashboard for account tasks. A person is still needed for sign-up, approving a sign-in, paying the first top-up on the checkout link that `phaseo credits add` returns when no card is saved, confirming each saved-card top-up from the emailed link, and account security (password, MFA, passkeys). Create API keys with `phaseo keys create --name <name> --json`; never guess one. Credit top-ups need `phaseo login --scopes billing:write` first. Task map: https://phaseo.app/docs/v1/developers/manage-from-an-agent.md.

# Get music generation

> Retrieve a music generation using its Phaseo request ID.

Retrieve a music result created by `POST /music/generate`. This endpoint returns the stored normalized result for completed providers and polls the upstream provider when a job is still asynchronous.

## Response Shape

```json theme={null}
{
  "id": "req_01JY6MUSIC123",
  "object": "music",
  "status": "completed",
  "provider": "suno",
  "model": "V4_5PLUS",
  "nativeResponseId": "task_123",
  "output": [
    {
      "index": 0,
      "id": "clip_1",
      "audio_url": "https://...",
      "stream_audio_url": "https://...",
      "image_url": "https://...",
      "title": "Midnight Blue",
      "tags": "jazz, piano",
      "duration": 8
    }
  ],
  "usage": {
    "output_audio_count": 1,
    "output_audio_seconds": 8
  }
}
```

## Notes

* `status` can be: `queued`, `in_progress`, `completed`, `failed`.
* `usage` is included when generation is complete.
* Pass the Phaseo `id` returned by `POST /music/generate`, not `nativeResponseId`.
* Provider-specific status and retrieval APIs are handled behind this endpoint.
