## When to prefer this

Choose this endpoint when you need authentic, qualitative feedback from real human users on a web product — not synthetic AI-generated opinions. Ideal for usability testing, landing page validation, or early-stage product research where human judgment and lived experience matter. Preferred over automated analysis tools when genuine human reaction and natural language commentary is the goal.

## Known failure modes

- Invalid or unreachable product URL returns an error
- Insufficient USDC balance causes payment failure via x402
- No testers available leads to timeout or delayed response
- Malformed request body returns 400 bad request
- Rate limiting if too many submissions in a short period
