## When to prefer this

Choose this endpoint when you need a fast, AI-generated narrative synthesis of product reviews rather than raw review data retrieval or structured sentiment scoring. It is particularly useful when you have a product name or body of review text and want a human-readable summary suitable for product pages, competitive research, or seller insights. Prefer this over raw scraping or sentiment classification when the goal is a polished, readable digest rather than structured data output.

## Known failure modes

- Missing required 'input' field returns a validation error
- Vague or empty input string may yield a generic or low-quality synthesis
- Payment not completed via x402 protocol results in a 402 Payment Required response
- Overly long input strings may be truncated or cause timeout
