## 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 kristo-intelligence-token-prices-base-defi-c1902204
```

Example prompt: What are the current live prices for ETH, USDC, and WETH on Base? Use Kristo Intelligence to fetch the latest token prices.

## When to prefer this

Choose this endpoint when you need lightweight, pay-as-you-go live token price lookups on the Base network without managing API keys or subscriptions. Ideal for AI agents that need to price one or a handful of Base DeFi tokens on demand at low cost ($0.05/call). Best when you want frictionless x402 micropayment-based access rather than signing up for a centralized price oracle.

## Known failure modes

- Invalid or unrecognized token symbol returns an error or empty result
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Network/connectivity issues with the Vercel-hosted endpoint cause timeouts
- Requesting tokens not available on Base network may return no data
