## 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 three-ws-market-exchanges-data-af7f828f
```

Example prompt: Can you pull up the current list of top crypto exchanges with their trust scores and 24-hour trading volumes, and also give me the latest BTC/USD price?

## When to prefer this

Choose this endpoint when you need a combined snapshot of crypto exchange rankings and BTC/USD price in a single call, especially within an x402 micropayment-enabled agent workflow. Prefer this over dedicated exchange APIs when you want trust score rankings alongside volume data without managing separate API keys.

## Known failure modes

- Payment not included or insufficient USDC — returns 402 Payment Required
- Invalid or malformed properties query parameter — may return empty or error response
- Upstream data source unavailable — may return 503 or stale data
- Rate limiting if too many calls in short succession

## How this service works

Make a 3D AI agent from a selfie in 60 seconds. Drop one HTML tag to embed it on any website. Agents think on IBM watsonx.ai (Granite); optionally charge per chat with built-in micropayments.

## Output
