## 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 chainray-stream-price-f7bc26b5
```

Example prompt: What's the current spot price of ETH on the Base network right now?

## When to prefer this

Use this endpoint when you need real-time or near-real-time on-chain price data for a token on a specific blockchain network, especially Base, Ethereum, or Polygon. Prefer over general crypto price APIs when you need on-chain sourced prices rather than exchange-aggregated prices, or when operating in a web3/DeFi context where chain-specific pricing matters.

## Known failure modes

- Unknown or unsupported token identifier returns 404 or error
- Unsupported chain parameter returns an error or empty result
- Network connectivity issues to the specified blockchain may cause delays or failures
- Payment of 0.02 USDC not received results in 402 Payment Required
- Invalid path parameter format returns 400 Bad Request
