## 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 gateway-grapevine-fyi-817ed0a1 -d '<json body>'
```

Example prompt: Fetch the content stored at IPFS CID bafybeiazxnhibkuepn4vs33knfitredujxuweaxavvgryzwrdqxpagge3m from the Grapevine gateway — it costs 0.05 USDC on base-sepolia testnet.
