## 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-price-lookup-via-coinpaprika-f1ddd654
```

Example prompt: What are the current price, market cap, and 24-hour change for bitcoin and ethereum right now?

## When to prefer this

Prefer this endpoint when you need keyless, real-time crypto price data (price, market cap, volume, 24h change) for one or more tokens by ID or symbol, especially when you want CoinPaprika's data without managing your own API credentials. Best for quick lookups and monitoring; not suited for historical price series or non-USD quote currencies.

## Known failure modes

- Unknown coin ID or symbol returns an error or empty result
- Only USD is supported as the quote currency; other currencies may not be available
- Comma-separated ID/symbol list malformed causes a 400 bad request
- CoinPaprika upstream outage causes stale or missing data
- Payment failure (x402) returns 402 before any data is served

## How this service works

Crypto token price and market data. Returns the live price of one or many tokens by coin id or ticker symbol, in a chosen vs-currency, with market cap, 24-hour volume, and 24-hour price change. For crypto price lookups, portfolio valuation, and market data feeds. Keyless, via CoinPaprika.

## Output

A JSON object mapping each requested coin ID or symbol to its live USD price, market capitalization, 24-hour trading volume, and 24-hour percentage price change, sourced from CoinPaprika.
