## 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-gateway-token-price-lookup-bdff11cf -d '<json body>'
```

Example prompt: What's the current price of ETH right now? Use the x402 token price tool and charge the $0.002 micropayment from my wallet.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use token price lookup without a subscription, especially in agentic workflows where micropayment via x402 on Base is already set up. Ideal for low-frequency price checks where a full market data API subscription is overkill.

## Known failure modes

- Unknown or unsupported token symbol returns an error or null price
- Payment failure if wallet has insufficient USDC balance on Base
- Network or RPC errors causing price feed unavailability
- Rate limiting or gateway downtime causing request failure
