## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability 1xu-trade-proof-verification-db70114b
```

Example prompt: Can you verify whether 1XU trade BOT1-1711234567-1234 is confirmed on-chain and get me the Basescan link and transaction hash?

## When to prefer this

Use this endpoint when you need to independently verify that a specific 1XU prediction market trade signal was actually executed and recorded on the Base blockchain, rather than just trusting a claimed track record. Ideal for auditing, due diligence, or confirming a trade proof before acting on signal performance claims.

## Known failure modes

- Trade ID not found — returns unverified or empty result
- Malformed trade ID format causes query failure
- Base network RPC issues may delay or fail proof retrieval
- Payment of $0.01 USDC not received — request rejected with 402

## How this service works
