## 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-spot-price-lookup-coinbase-binance-9babedad
```

Example prompt: What's the current spot price of ETH in USD right now — and which exchange is it coming from?

## When to prefer this

Use this endpoint when you need a single, fast, current USD price for a specific cryptocurrency and don't need historical data, OHLCV candles, or market cap figures. It is ideal for quick price checks, portfolio valuation at a point in time, or triggering logic based on current price levels. Prefer this over the full market snapshot endpoint when you only need the price and don't want to pay for extra data fields.

## Known failure modes

- Unknown or unsupported symbol returns an error (e.g. a misspelled or delisted ticker)
- Both Coinbase and Binance unavailable causes a service failure response
- Rate limiting or payment failure results in a 402 or 429 response
- Network timeout from the ngrok tunnel may cause intermittent failures

## How this service works

Real-time spot price in US dollars for any major cryptocurrency, including BTC, ETH, SOL and hundreds of others. Returns the current price and the exchange it came from, sourced live from Coinbase with an automatic Binance fallback. Use this when you need a fast, accurate, current price for a crypto asset.

## Output

Returns a JSON object containing the asset symbol (e.g. ETH), the current USD price as a number, the exchange the price was sourced from (e.g. coinbase or binance), and a timestamp of when the price was fetched.
