```sh
zero fetch --capability otto-ai-x402-feedback-endpoint-885380c2 -d '<json body>'
```

Example prompt: Can you send feedback to Otto AI about the market intelligence service — the crypto news sentiment endpoint returned stale data and the rankings seemed off?

## When to prefer this

Use this endpoint when you need to programmatically submit user feedback, bug reports, or feature requests specifically to the Otto AI x402 platform after interacting with one of its 64 pay-per-call AI services.

## Known failure modes

- Missing or malformed properties field returns 400 bad request
- Service unavailable if Otto AI backend is down
- Payment not included or insufficient USDC returns 402 payment required
- Empty feedback body may be rejected

## How this service works

Otto X402 Router — Feedback & Refunds. Rate a paid Router call by its payment tx_hash. An approved refund returns this $0.001 fee PLUS the refundable amount, only to the original payer, never above what you paid Otto.

## Output

A confirmation that the feedback was received and stored by the Otto AI x402 platform, likely including a status or acknowledgment message.
