```

Example prompt: Run a sentiment analysis on this text and tell me if it's positive or negative: 'The onboarding process was smooth but the support team took forever to respond.'

## When to prefer this

Choose this endpoint when you need a simple, fast boolean sentiment classification on a text string and are operating within an x402 payment-capable agent pipeline. Best suited for high-volume triage scenarios where a binary positive/negative signal is sufficient and you want to avoid the token overhead of in-context LLM sentiment analysis.

## Known failure modes

- Missing or empty 'data' field returns a validation error
- Non-string input in 'data' field may cause a processing error
- Payment failure via x402 protocol blocks execution
- Ambiguous or very short text may produce unreliable boolean output
- Server-side MCP node unavailability returns a 5xx error
