## 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 tradesonar-market-detail-bdf753e8
```

Example prompt: Pull up the current price, open interest, and funding rate term structure for ETH-USD on TradeSonar right now.

## When to prefer this

Use this endpoint when you need real-time price, open interest, and funding rate term structure for a specific dYdX perpetual market in a single call. Prefer this over candlestick or trade history endpoints when you need a current market snapshot rather than historical series data. Best for pre-trade analysis, funding rate monitoring, or crowding signal assessment on dYdX.

## Known failure modes

- Invalid or unsupported ticker (e.g. ETH-USDT instead of ETH-USD) returns a 404 or error response
- Network timeout if dYdX on-chain data is temporarily unavailable
- Missing pathParam ticker results in a malformed request
- Payment failure via x402 protocol returns 402 Payment Required
