## 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 crypto-token-prices-eae90670
```

Example prompt: What are the current USD prices and 24-hour changes for BTC, ETH, and SOL right now?

## When to prefer this

Choose this endpoint when you need real-time spot prices and 24h change data for a specific set of tokens (up to 20) identified by symbol, CoinGecko ID, or on-chain contract address. Prefer this over the Top Crypto by Market Cap endpoint when you need prices for specific tokens — especially obscure or on-chain tokens — rather than a ranked market overview.

## Known failure modes

- Unknown or misspelled symbol returns an error or null entry for that token
- More than 20 tokens requested in a single call exceeds the limit
- Invalid chain:contract address format results in lookup failure
- Network or upstream CoinGecko data unavailability causes a timeout or 503
- Token not yet listed on CoinGecko returns no price data

## How this service works

Current USD price and 24h change for up to 20 crypto tokens per call, by symbol (BTC, ETH, SOL, PEPE), CoinGecko id or chain:contract address (base:0x833589..., ethereum:0x...). Covers thousands of coins and on-chain tokens. Use for portfolio valuation, trading decisions or answering what a token costs now.

## Output

Returns a JSON object keyed by each requested token identifier, containing the current USD price and the 24-hour percentage change for each token. Covers thousands of coins including major assets, altcoins, and on-chain tokens via chain:contract lookups.
