## 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-address-activity-feed-52750751 -d '<json body>'
```

Example prompt: Pull up the recent transaction history for Robinhood Chain address 0xABC123... — I want to see the hashes, methods, statuses, counterparties, and values for each transaction.

## When to prefer this

Choose this endpoint when you need recent transaction history specifically on Robinhood Chain (rhchain) for a given wallet address. It is purpose-built for Robinhood Chain activity rather than generic EVM chains, making it the right choice when your user is specifically investigating rhchain wallet behavior, auditing a counterparty on that network, or monitoring tokenized-asset trading activity native to Robinhood's blockchain.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Address with no Robinhood Chain activity returns an empty transaction list
- Network or upstream Robinhood Chain RPC issues may cause timeouts
- Incorrect request body structure (missing address field) returns a validation error
- Payment failure (insufficient USDC balance) returns a 402 error

## How this service works
