## 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 quicknode-network-cdded595 -d '<json body>'
```

Example prompt: Use QuickNode to call eth_getBalance for address 0xAbC1234... on Ethereum mainnet and tell me the current balance in wei.

## When to prefer this

Choose this endpoint when you need high-volume, low-cost blockchain RPC calls at $0.00001 per call — ideal for read-heavy workloads like indexing, monitoring, or analytics where cost efficiency matters. Prefer this tier over the $0.001 tier when you are making many calls and cost is a priority. Supports 80+ blockchains including EVM-compatible chains and Solana.
