## 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 token-price-lookup-live-historical-x402utils-3583e273
```

Example prompt: What's the current price of Bitcoin and Ethereum right now? Use their CoinGecko IDs — bitcoin and ethereum.

## When to prefer this

Choose this endpoint when you need real-time or historical token prices across any blockchain, especially when tokens are identified by CoinGecko IDs or chain:contract address pairs. It is ideal for multi-chain DeFi workflows, portfolio valuation, price-triggered automations, or any agent that needs structured price data paid per call with USDC via x402 rather than a subscription API key.

## Known failure modes

- Invalid or unrecognized coin ID returns an error or empty entry for that coin
- Malformed comma-separated coin list causes a 400-level error
- Network or upstream CoinGecko outage may return stale or unavailable data
- Missing x402 payment header results in a 402 Payment Required response
- Requesting too many coins in a single call may result in timeouts or truncated results

## How this service works

Live and historical token prices for agents, any chain: coingecko ids or chain:contract addresses, plus % change over a period. Paid per call via x402 (USDC on Base).

## Output

Returns a JSON object with a `prices` map keyed by coin identifier (e.g. 'coingecko:bitcoin'), each containing the current USD price and token symbol, plus optional percentage change over the requested period.
