## 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 musicwire-musicxml-renderer-071381ad -d '<json body>'
```

Example prompt: Please render this MusicXML score into both a PDF and an MP3, and run QC to confirm it's in D major at 120 BPM — here's the full MusicXML document: [document].

## When to prefer this

Choose this endpoint when you have a complete MusicXML document and need deterministic, multi-format rendering with built-in automated quality control in a single API call. It is especially valuable when you need to validate musical constraints (key, tempo, duration, mode) alongside rendering, avoiding separate validation steps. Prefer it over general-purpose music tools when you need multiple output formats simultaneously (e.g. PDF for printing and MIDI for playback) from one request.

## Known failure modes

- Invalid or malformed MusicXML document returns a parse error
- Unsupported or missing format enum value causes validation failure
- QC constraint mismatch (e.g. wrong key or tempo) returns a failed QC report with details
- Empty formats array rejected due to minItems:1 constraint
- Oversized MusicXML documents may time out or exceed payload limits
- x402 payment failure blocks the request before rendering begins

## How this service works

MusicXML render with deterministic automated QC and artifacts.

## Output

Returns one or more rendered artifact files in the requested formats (mscz, pdf, svg, png, midi, mp3) along with a deterministic QC report indicating whether the score passes the specified tempo, duration, key, and mode constraints.
