## 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 by-symbol-token-price-lookup-a057095a -d '<json body>'
```

Example prompt: Can you look up the current prices of ETH and USDC on eth-mainnet using Alchemy's price feed?

## When to prefer this

Use this endpoint when you need fast, on-demand price lookups for one or more crypto tokens by their ticker symbols (e.g. ETH, USDC, WBTC) on a specific EVM-compatible network. Prefer this over address-based lookups when you know the symbol but not the contract address. It is ideal for portfolio valuation, DeFi analytics, and real-time price checks across networks supported by Alchemy.

## Known failure modes

- Invalid or unsupported network slug returns an error
- Unknown or unsupported token symbol returns empty or error response
- Malformed comma-separated symbols list causes a 400 bad request
- Network connectivity or Alchemy upstream outage causes a 502/503
- Missing required fields (network or symbols) returns a validation error
