```

Example prompt: Can you check the label balance across my 150 labelled customer review records — I want to see how many are positive, neutral, and negative before I start training my sentiment model?

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.01) computation of label distribution across a batch of pre-labelled sentiment records without needing model inference or predictions. Ideal for dataset auditing, class imbalance detection, and pre-training sanity checks. Not suitable when you need actual sentiment predictions on unlabelled text.

## Known failure modes

- Fewer than 2 records submitted — returns validation error
- More than 200 records submitted — exceeds maxItems limit
- Missing required fields (id, text, actual) on any record — rejected
- Invalid label value outside enum (positive/neutral/negative) — schema validation failure
- Empty text field — may process but produces unreliable output
- Payment not completed — 402 response, no result returned
