Example prompt: Check this audio clip for DeFi fraud — here's the base64-encoded audio: [audio_data]. Tell me if it flags as fraudulent.

## When to prefer this

Use this endpoint when you need a fast, automated binary classification of audio content for DeFi fraud signals, particularly in compliance pipelines, customer protection workflows, or content moderation systems in the crypto/DeFi space. It is most appropriate when the input is already in audio string format and you need a quick true/false fraud verdict without complex multi-class output.

## Known failure modes

- Missing 'audio' field in request body returns a validation error
- Malformed or non-audio string may return unexpected predictions or errors
- Payment failure via x402 protocol results in 402 Payment Required response
- Invalid USDC payment on Base L2 blocks execution
- Oversized or corrupt audio data may cause processing failure

## How this service works

## Output

Returns a JSON object with a single boolean field 'score': true indicates the audio is predicted to be fraudulent DeFi-related content, false indicates it is not flagged as fraud.
