## 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 bitstamp-ticker-via-sitecheck-crypto-finance-77cbdab1
```

Example prompt: What's the current BTC/USD price on Bitstamp right now — give me the bid, ask, last traded price, and 24-hour percent change?

## When to prefer this

Choose this endpoint when you need real-time Bitstamp-sourced ticker data with no API key or account signup, billed only on successful calls via micropayment. Ideal for agents that need trustworthy, exchange-official crypto pricing without managing API credentials, or when Bitstamp's liquidity and EUR pairs are specifically required for comparison or arbitrage logic.

## Known failure modes

- Invalid or unsupported pair symbol returns an error — pair must be lowercase and valid on Bitstamp (e.g. btcusd, ethusd, btceur)
- Missing required 'pair' query parameter causes a 400-level error
- Bitstamp upstream API unavailability may result in stale or failed responses
- Payment failure on the x402 protocol results in no charge and no data returned

## How this service works

Bitstamp spot ticker for one pair (e.g. btcusd, btceur): last, bid, ask, 24h open/high/low, volume and VWAP, from Bitstamp's public ticker endpoint.

## Output

A JSON object containing the trading pair symbol, current bid and ask prices, last traded price, 24-hour open, high, low, volume, VWAP, percent change, and timestamps for when the data was checked and last updated by Bitstamp.
