## 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 erc20-token-usd-price-with-24h-change-via-dex-aware-indexer-6175a098
```

Example prompt: What's the current USD price and 24-hour percent change for the ERC20 token at contract address 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum mainnet, and which exchange is being used to price it?

## When to prefer this

Use this endpoint when you need a fast, DEX-aware USD price for a specific ERC20 token identified by contract address and chain, especially when you also want the 24-hour price change and the source exchange in a single call. Prefer this over generic CeFi price APIs when the token is primarily traded on decentralized exchanges or when the contract address (not ticker symbol) is your primary identifier.

## Known failure modes

- Invalid or unrecognized contract address returns an error or empty result
- Unsupported chain ID returns a 400 or 404 error
- Token not indexed by the DEX price source returns no price data
- Missing required parameters (contract address or chain) returns a validation error
- API key absent or invalid returns a 401/402 authentication error
- Very low liquidity tokens may have stale or unreliable price data
