## 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 net-protocol-relay-fund-223e7068 -d '<json body>'
```

Example prompt: Fund the Net Protocol relay backend wallet on Base (chain 8453) with USDC so the relay service can keep processing transactions.

## When to prefer this

Use this endpoint when you need to fund the Net Protocol relay backend wallet specifically on the Base chain (chain 8453), enabling relay transactions to be processed. Choose this over generic wallet funding when working within the Net Protocol relay ecosystem and x402 payment infrastructure.

## Known failure modes

- Insufficient USDC payment — payment of less than $0.25 USDC rejected
- Invalid chain ID — only chain 8453 (Base) is supported at this endpoint
- Wallet address not recognized or relay wallet unreachable
- x402 payment header missing or malformed — request rejected before processing
- Network congestion on Base chain causes delayed confirmation
