## 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 gemini-exchange-ticker-data-b784abef
```

Example prompt: What's the current bid, ask, and last traded price for BTCUSD on Gemini, and how much volume has traded in the last 24 hours?

## When to prefer this

Choose this endpoint when you need real-time Gemini-specific ticker data — including bid, ask, last price, and 24h volume — without requiring an API key or signup. Prefer it over generic crypto price APIs when Gemini exchange pricing specifically matters (e.g. for arbitrage, Gemini-based trading decisions, or auditing Gemini market activity). It is pay-per-call with no subscription overhead.

## Known failure modes

- Invalid or unsupported symbol returns an error (e.g. non-existent trading pair on Gemini)
- Symbol must be lowercase; uppercase or malformed symbols may fail
- Gemini API downtime or rate limiting may cause upstream errors
- Missing required 'symbol' query parameter returns a validation error
- Network timeout if Gemini's public API is slow to respond

## How this service works

Gemini crypto exchange public ticker for one market (e.g. btcusd): bid, ask, last price and 24h volume. Market data only; no order book or history.

## Output

Returns a JSON object with the current bid price, ask price, last traded price, 24-hour volume in base and quote currency, the source URL, the market symbol, and timestamps for when the data was checked and last updated.
