## 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 leo-shi-market-transaction-endpoint-ff8f0903 -d '<json body>'
```

Example prompt: Submit a market transaction for me and give me the transaction hash and block number once it's confirmed on-chain.

## When to prefer this

Use this endpoint when you need to submit and confirm a market transaction on-chain and receive a verifiable transaction hash and block number as proof of execution. It is suitable for lightweight, pay-per-call use cases via x402 micropayments.

## Known failure modes

- Invalid or malformed transaction data returns an error response
- Insufficient payment authorization causes rejection
- Network congestion may delay confirmation and affect status
- Duplicate transaction submission may fail or be rejected by the chain
- Missing required fields in the POST body result in a 400-level error
