## 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 x402-base-network-payment-endpoint-f767a07a
```

Example prompt: Pay $1 USDC on the Base network using the x402 protocol at basex402.ai to unlock access to this paywalled resource.

## When to prefer this

Choose this endpoint when you need to fulfill an x402 HTTP 402 Payment Required response specifically on the Base network with a $1 USDC micropayment. Prefer this over other x402 endpoints when the resource is hosted at basex402.ai or explicitly requires Base network USDC.

## Known failure modes

- Insufficient USDC balance — payment cannot be completed
- Invalid or missing x402 payment header — 402 response returned
- Base network congestion or RPC failure — transaction times out
- Incorrect network — payment sent on wrong chain
- Payment already processed — duplicate transaction rejected
