## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability api-zeroclick-ac-minimax-music-generation-x402-47fb826b -d '<json body>'
```

Example prompt: Using the MiniMax music-2.6 model, generate an upbeat lo-fi hip-hop instrumental track from the prompt 'chill coffee shop vibes with soft piano and vinyl crackle' — go ahead and authorize the $0.15 payment.

## When to prefer this

Choose this endpoint when you need to generate original music or AI-powered song covers using MiniMax's music-2.6 or music-cover models and your workflow supports x402 / MPP micropayment flows. Prefer this over ElevenLabs music or other proxies when MiniMax's specific audio style or licensed cover capability is required.

## Known failure modes

- Payment not authorized or insufficient USDC balance — 402 Payment Required returned
- Invalid or unsupported model name — 400 Bad Request
- Missing or malformed audio reference for cover generation — 422 Unprocessable Entity
- Upstream MiniMax API unavailable or rate-limited — 502 or 503 error
- Request timeout during long music generation — 504 Gateway Timeout
- Buyer payment consent not confirmed — request blocked before forwarding

## How this service works

Generate original music or licensed covers using MiniMax models (music-2.6, music-cover, and free trial variants). This listing forwards validated, paid requests to the verified upstream POST /v1/music_generation endpoint at https://api.minimax.io. Agents must validate inputs, confirm buyer payment consent, and follow payment-challenge flows (x402 / MPP) before forwarding caller audio-generati...[truncated]

## Output

A generated music file or URL to the produced audio track, along with generation metadata such as model used and task status, returned after the x402 payment challenge is resolved and the upstream MiniMax music_generation endpoint processes the request.
