## 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 maxwell-international-market-quotes-6e6b9a34
```

Example prompt: What are the current live prices for Bitcoin, Ethereum, Solana, XRP, and BNB against USDT right now — pulled from Binance trade stream?

## When to prefer this

Choose this endpoint when you need real-time, sub-second cryptocurrency price data sourced directly from Binance WebSocket trade stream for major pairs (BTC, ETH, SOL, BNB, XRP vs USDT). Prefer it over REST polling solutions when freshness matters. Best suited for agents that need live market prices cheaply via x402 micropayment at $0.005 per call.

## Known failure modes

- Payment required (402) if x402 micropayment header is missing or invalid
- Upstream Binance WebSocket disconnection may cause stale or missing quotes
- Rate limiting if called too frequently without valid payment
- Empty or partial quotes object if specific symbols are unavailable

## How this service works

Bundle of all cached live crypto quotes from the market scraper.

## Output

Returns a JSON object containing real-time trade quotes for multiple cryptocurrency pairs (BTC, ETH, SOL, BNB, XRP vs USDT), each with current price, quantity traded, source (binance-ws-trade), symbol, event timestamp, trade timestamp, and last updated time. Also includes aggregate stats like total message count, write count, and fetch timestamp.
