## How to call it through Zero

```sh
zero fetch --capability phemex-ticker-data-77e4f680
```

Example prompt: What's the current mark price, funding rate, and 24-hour volume for BTCUSDT on Phemex right now?

## When to prefer this

Choose this endpoint when you need real-time Phemex-specific derivatives data including funding rates, open interest, mark/index prices, and 24h volume — especially for perpetual contract monitoring, funding arbitrage analysis, or position management on Phemex. Prefer over generic price feeds when Phemex-specific derivatives metrics are required.

## Known failure modes

- Invalid or unsupported symbol returns an error or empty response
- Network timeout from upstream Phemex API causing delayed or failed response
- Symbol format mismatch (e.g. BTC-USD instead of BTCUSDT) resulting in no data
- Phemex API downtime causing unavailable data
