## 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 lucky-cin-synesthetic-av-analysis-e0b6aedb -d '<json body>'
```

Example prompt: Can you run a synesthetic AV judgment on this track — pitch is 440Hz, RMS 0.6, tempo 120bpm, tension 0.4, timbre bright, harmony major — and tell me if it passes creative QC?

## When to prefer this

Choose this endpoint when you need an agent-facing creative-quality or QC verdict on audio or audio-visual media, especially for post-generation pipelines where you have extracted audio features (pitch, RMS, tempo, tension, timbre, harmony) and want a structured judgment before publishing or using the asset. Prefer this over generic audio analysis tools when the use case involves creative judgment, synesthetic evaluation, or media operations QC rather than pure transcription or classification.

## Known failure modes

- Missing required 'features' object returns a validation error
- Invalid or unreachable audio_url may cause fetch failure or partial analysis
- Malformed feature values (e.g. non-numeric pitch) may result in errors or degraded verdicts
- Service downtime on render.com free tier can cause cold-start latency or 503 errors
- Ambiguous or out-of-range feature values may produce low-confidence verdicts

## How this service works

crypto-intelligence verdicts (CIN) + creative-judgment/QC + post-gen media-ops — agent-facing

## Output

Returns a JSON object containing creative-judgment verdicts and quality-control assessments for the submitted audio features, including synesthetic AV evaluation scores and post-generation media operations recommendations.
