## 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 agentrxi-crypto-price-lookup-f82fdaeb
```

Example prompt: What are the live prices, 24h changes, and market caps for Bitcoin, Ethereum, and Solana in USD and EUR right now?

## When to prefer this

Choose this endpoint when you need real-time cryptocurrency prices with 24h change and market cap in a single call, especially when querying multiple coins across multiple fiat currencies simultaneously. It is ideal for portfolio tracking, price alert agents, and dashboards. Prefer over raw CoinGecko API access when you need a pay-per-call, no-subscription model via x402.

## Known failure modes

- Invalid or unrecognized coin symbol/ID returns an error or omits that coin from results
- Requesting more than 50 coins or more than 10 currencies may exceed limits
- Invalid currency code causes a bad request error
- Payment failure (x402) if USDC balance is insufficient
- Rate limiting or upstream CoinGecko outage may cause temporary unavailability

## How this service works

Live crypto prices with 24h change and market cap. Pass symbols (btc,eth,sol) or CoinGecko ids, up to 50 coins, in up to 10 currencies (usd,cad,eur...).

## Output

A JSON object keyed by coin symbol or CoinGecko ID, containing the current price, 24-hour percentage change, and market capitalization for each requested coin, denominated in each requested currency.
