Example prompt: Can you check the label balance in my customer feedback dataset? I have 200 records each labelled as quality, price, delivery, or support — I want to see the distribution breakdown across those four categories.

## When to prefer this

Choose this endpoint when you need a quick, lightweight check of label balance across customer feedback records categorized into quality, price, delivery, or support themes — especially useful before training a naive-Bayes or similar classifier, or when auditing annotation batches for class imbalance. It is ideal for small local datasets up to 200 records and does not require a hosted model or external training infrastructure.

## Known failure modes

- Fewer than 2 records submitted — minimum input not met
- More than 200 records submitted — exceeds maximum allowed batch size
- Invalid label value used (only quality, price, delivery, support are allowed)
- Missing required fields (id, text, or actual) on any record
- Empty text field or id exceeding 80 characters — schema validation error
- Payment not included or insufficient — x402 payment required at $0.01 USDC
