## 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 eudata402-crypto-token-price-by-chain-contract-address-5951bcc0
```

Example prompt: What's the current USD price of the USDC token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on ethereum — I need the symbol, price, decimals, and confidence score.

## When to prefer this

Use this endpoint when you need real-time token prices by contract address across multiple chains without managing a DefiLlama API key. It is ideal for DeFi applications, portfolio trackers, or agents that need to price arbitrary ERC-20 or SPL tokens by their on-chain address rather than by symbol name, and when cross-chain coverage (ethereum, base, arbitrum, solana, etc.) is required in a single unified interface.

## Known failure modes

- Unknown or unsupported chain name returns an error or empty result
- Invalid or non-existent contract address returns no price data
- Token not indexed by DefiLlama returns null or low confidence score
- Misspelled chain name (e.g. 'eth' instead of 'ethereum') may yield no result
- Newly deployed contracts may not yet be tracked, returning empty data

## How this service works

Current crypto token price by chain + contract address (official DefiLlama, keyless — price-by-contract is key-gated elsewhere). POST {chain, address}. Returns {symbol, price_usd, decimals, confidence}.

## Output

Returns a JSON object containing the token's symbol (e.g. 'USDC'), current price in USD (price_usd), decimal precision (decimals), and a confidence score indicating the reliability of the price data from DefiLlama.
