## 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 synapse-api-berachain-rpc-8083cf7a -d '<json body>'
```

Example prompt: Call the Berachain RPC endpoint with method 'eth_getBalance' and params ['0xYourWalletAddress', 'latest'] to check the current BERA balance of that address.

## When to prefer this

Choose this endpoint when you need pay-per-call, no-subscription access to Berachain RPC without managing your own node or committing to a monthly plan. Ideal for low-volume or sporadic Berachain queries billed in USDC via x402.

## Known failure modes

- Invalid or unsupported RPC method returns a JSON-RPC error object
- Malformed params array causes a parse or invalid params error
- Payment failure via x402 protocol results in 402 response before RPC execution
- Network congestion or Berachain node unavailability causes timeout
- Submitting a malformed raw transaction returns execution reverted or invalid transaction error

## How this service works
