## 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 alchemy-bf85c539 -d '<json body>'
```

Example prompt: What's the current USD price of the USDC token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum mainnet?

## When to prefer this

Use this endpoint when you have specific token contract addresses (not symbols) and need current real-time prices, especially for less common or chain-specific tokens where a symbol lookup might be ambiguous. Prefer this over the symbol-based endpoint when you know the exact contract address to avoid symbol collision across chains.

## Known failure modes

- Invalid or unrecognized contract address returns an error or null price
- Unsupported chain results in an error response
- Rate limiting or payment failure via x402 protocol returns 402 Payment Required
- Malformed request body returns 400 Bad Request
- Token exists on chain but has no price data available

## How this service works
