## 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-crowding-signals-api-8e627ad0
```

Example prompt: What are the crowding signals for BTC-USD on dYdX right now — specifically the long/short ratio, squeeze score, and how concentrated whale holders are?

## When to prefer this

Choose this endpoint when you need on-chain crowding and positioning intelligence for dYdX perpetual markets — specifically long/short ratio, squeeze risk, and whale concentration — rather than price or funding rate data. Ideal for trading bots, risk monitors, and dashboards that need to detect crowded trades or squeeze setups on dYdX.

## Known failure modes

- Unknown or unsupported ticker symbol — returns 404 or empty data
- Replica lag too high causing stale data — freshness timestamp will reflect lag
- Payment not provided or insufficient — x402 payment required error
- Rate limiting if too many calls per second
- Network or upstream dYdX node unavailability causing 503

## 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

A JSON object containing: ticker symbol, squeeze direction (squeezeDir), squeeze score (squeezeScore), top holder percentage (topHolderPct), top 5 holder percentage (top5HolderPct), long/short ratio (longShortRatio), long notional in USD (longNotionalUsd), short notional in USD (shortNotionalUsd), and total open interest in USD (openInterestUsd). Each response is timestamped with a data_as_of field indicating block height and replica lag for freshness tracking.
