## 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 robinhood-chain-transaction-lookup-8a800898 -d '<json body>'
```

Example prompt: Can you check whether transaction 0xabc123... on Robinhood Chain went through — I need to know the status, block number, and how much gas was used.

## When to prefer this

Use this endpoint when you specifically need to look up a transaction on Robinhood Chain (the chain used by Robinhood for tokenized equities and on-chain trading). Prefer this over generic EVM transaction explorers when working within the Robinhood Chain ecosystem, especially for tokenized stock transfers or Robinhood-native DeFi activity.

## Known failure modes

- Transaction hash not found — returns error if the hash doesn't exist on Robinhood Chain
- Invalid hash format — malformed or non-hex hash causes a bad request error
- Transaction still pending — status returned as pending with incomplete finality data
- Network or RPC unavailability — upstream Robinhood Chain node may be unreachable
- Payment failure — $0.005 USDC charge not processed results in 402 error
