## 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-dydx-whale-positions-api-555fbeda
```

Example prompt: Pull up the current open positions for dYdX address dydx1abc123xyz on TradeSonar — I want to see what markets they're in, whether they're long or short, their position sizes, and unrealized PnL.

## When to prefer this

Use this endpoint when you need to inspect the current open positions of a specific known dYdX wallet address — especially for smart money tracking, copytrading research, or whale monitoring workflows. Prefer this over generic market endpoints when you have a target address and want position-level detail (size, side, PnL, entry price) rather than aggregate market signals.

## Known failure modes

- Invalid or malformed dYdX address returns a 400 or 404 error
- Address with no open positions returns an empty positions array
- Stale data due to replica lag may cause slightly outdated position values
- Rate limiting or payment failure (x402) if USDC balance is insufficient
- Address that has never traded on dYdX may return empty or not-found response

## How this service works

TradeSonar: dYdX on-chain smart-money, funding and crowding signals. Every response is stamped with data_as_of freshness (block height + replica lag).

## Output

Returns a list of current open positions for the specified dYdX address, each including the market ticker, side (long/short), position size in USD, entry price, current mark price, unrealized PnL in USD, and the timestamp the position was opened. The response is stamped with a data_as_of field indicating freshness via block height and replica lag.
