## 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 foundry-crypto-price-lookup-19af08f6 -d '<json body>'
```

Example prompt: What are the current USD prices for BTC, ETH, and SOL right now? Use the DefiLlama-backed price feed.

## When to prefer this

Choose this endpoint when you need real-time USD prices for one or more cryptocurrencies by ticker symbol or on-chain token address, especially when DefiLlama coverage is desired. It handles both well-known coins (BTC, ETH) and obscure DeFi tokens via chain:address lookup in a single call, making it ideal for portfolio calculations, price checks, or DeFi analytics. Prefer this over CoinGecko-direct or CoinMarketCap integrations when you need DefiLlama's broad DeFi token coverage.

## Known failure modes

- Unknown or misspelled coin symbol returns it in the 'unresolved' array rather than throwing an error
- Invalid chain:address format may result in unresolved entry
- Exceeding 20 coins in a single request may result in truncation or error
- DefiLlama upstream outage may cause stale or unavailable prices
- Very new or illiquid tokens may have no price data and appear as unresolved

## How this service works
