## 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 agent402-exchange-tickers-a57d1794
```

Example prompt: Pull the live tickers for ethereum and bitcoin on Binance — I want to see the current USD price, 24-hour volume, spread, and trust score for each pair.

## When to prefer this

Use this endpoint when you need live, per-exchange ticker data (price, volume, spread, trust score) sourced from CoinGecko without managing API keys — especially in agent workflows that pay per call over x402. Prefer over direct CoinGecko API when you want no-signup access with USDC micropayments and built-in filtering by coin id.

## Known failure modes

- Invalid or unknown exchange id returns empty tickers or error
- Invalid coin id filter silently returns no matching tickers
- Page number beyond available data returns empty result set
- Rate limit or payment failure returns 402 with no data
- Stale upstream data reflected in ticker timestamps

## How this service works

Markets (tickers) listed on one exchange: base/target pair, last price, 24h volume, USD- and BTC-converted last price and volume, bid-ask spread %, trust score (green/yellow/red), anomaly and stale flags, trade URL and last trade time. Filter by `coins` (coin ids, max 10); pages of up to 100 tickers (`page`), trimmed to `limit` (default 50). Where is a coin actually trading, at what spread, and is the volume trusted. Cached in-process for 60 seconds.

## Output

Returns a paginated list of ticker objects for the requested exchange, each containing base/target trading pair, last price in USD and BTC, 24h volume in USD, spread percentage, trust score (green/yellow/red), trade URL, coin IDs, last traded timestamp, and stale/anomaly flags. Also includes exchange name, source (CoinGecko), fetch timestamp, and total count.
