## 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 phantom-api-robinhood-rpc-endpoint-69f4ca11 -d '<json body>'
```

Example prompt: Call the Robinhood blockchain RPC with method eth_getBalance and params for address 0xAbC123 to get its current on-chain balance.

## When to prefer this

Choose this endpoint when you need direct JSON-RPC access to the Robinhood blockchain network specifically, and want pay-per-call pricing via x402 without a subscription. Prefer it over generic RPC providers when targeting this specific chain and when per-call micropayment billing fits your usage pattern.

## Known failure modes

- Invalid or unsupported RPC method name returns an error response
- Malformed params array causes a parse or invalid params error
- Payment not received results in HTTP 402 response blocking the call
- Network or chain unavailable returns a connection or timeout error
- Requesting data for a non-existent block or transaction returns null result

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

## Output

Returns a standard JSON-RPC response object containing the result of the requested blockchain method call, including on-chain data such as balances, block information, transaction receipts, smart contract return values, or network state depending on the method invoked.
