## 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-derivatives-ticker-feed-bf9b3f48
```

Example prompt: Pull the latest BTC futures ticker data — I want to see the current price, 24-hour volume, funding rate, and open interest from the derivatives market.

## When to prefer this

Use this endpoint when you need real-time cryptocurrency derivatives data — specifically funding rates, open interest, and perpetual futures prices — and are operating in a micropayment-enabled (x402) environment. Prefer this over traditional market data APIs when your agent stack already handles USDC payments via x402 and you want a single lightweight call for derivatives snapshots.

## Known failure modes

- Missing or malformed properties filter returns empty or unexpected ticker set
- Service unavailable if upstream exchange data feeds are down
- 402 Payment Required if USDC micropayment of $0.001 is not included
- Stale data if exchange APIs are delayed or throttled

## 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

A JSON object containing an array of ticker objects, each with fields: symbol (e.g. BTCUSDT), market (exchange name like 'Binance (Futures)'), price (current mark price), volume_24h (24-hour trading volume in USD), funding_rate (current periodic funding rate), and open_interest (total open interest in USD).
