## 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 hearth-token-price-5e83a736
```

Example prompt: What's the current USD price of USDC at contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base?

## When to prefer this

Use this endpoint when you need a fast, on-demand USD price lookup for a specific EVM token by contract address across Base, Ethereum, Arbitrum, or Optimism, especially in pay-per-call agent workflows using x402/USDC micropayments. Prefer this over broader DeFi data APIs when you need a lightweight, single-token price check with a confidence score and don't want subscription overhead.

## Known failure modes

- Invalid or unsupported chain name returns an error
- Unknown or unrecognized contract address may return no price data
- Network latency or upstream price feed unavailability may delay or fail the response
- Payment failure via x402 protocol blocks the request
