## 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`):

```

Example prompt: Fetch the private Pinata file with CID bafkreifm6sroj5jdnkbjojh5ra5hiybj3rwq52focjvaup7dn5amqll4ne — it costs $0.001 USDC to access.
