Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 suno-via-locus-x402-ai-music-generation-1f28e3ee -d '<json body>'
```

Example prompt: Create a full song called 'Midnight Drive' — make it a cinematic synthwave track with male vocals, using Suno's V5 model. The lyrics should be about cruising through a neon-lit city at night; avoid anything heavy metal or distorted.

## When to prefer this

Choose this endpoint when you need AI-generated music with fine-grained control over style, lyrics, vocals, and instrumental mode — especially when you want to leverage Suno's state-of-the-art V4/V5 models via a pay-per-call x402 micropayment flow without managing a Suno API account directly. Prefer it over generic TTS or sound-effect APIs when the goal is full song or music track creation.

## Known failure modes

- Invalid or missing required fields in customMode (style, title, prompt) returns a validation error
- Unsupported model string causes rejection
- prompt exceeding character limits (3000–5000 chars) may be truncated or rejected
- Payment failure over x402 protocol blocks the request
- Webhook/callBackUrl unreachable means no notification; must poll statusUrl manually
- Generation may fail or return low-quality output if style and negativeTags conflict heavily
