## 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 scrapling-x402-coin-lookup-8c721637
```

Example prompt: What is the current price, market cap, and 24-hour change for Bitcoin right now?

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.001 USDC) lookup of a single cryptocurrency's price and key market metrics by symbol or name, especially in an autonomous agent context using the x402 micropayment protocol. Prefer it over heavier market data APIs when only basic price/market cap/ATH data is needed.

## Known failure modes

- Unknown or misspelled symbol/name returns an error or empty result
- Rate limiting if called too frequently
- Payment failure via x402 protocol results in 402 response and no data
- Stale data if upstream CoinGecko feed is delayed

## How this service works

Current price of BTC, ETH or any top-500 coin: USD price, market cap, 24h volume, 1h/24h/7d % change and % below all-time high. Example: q=btc, q=ethereum, q=solana. Data refreshed about every 30 min

## Output

A JSON object containing the coin's full name, ticker symbol, current price in USD, 24-hour price change percentage, market capitalization in USD, and percentage change from all-time high.
