How this service works
Smart-money flow (open/close/increase/decrease/flip events)
Output
A JSON array of flow events, each containing the wallet address, ticker, trade side (buy/sell), action type, USD size in and out, classification label (e.g. whale/smart-money tier), and timestamp — plus a data_as_of freshness stamp with block height and replica lag.
Example use cases
Pre-trade smart money direction check
“Before I open a BTC-USD perp position, check TradeSonar for the last 30 minutes of whale flow on dYdX — are big wallets net buying or selling? Show me up to 100 events.”
Unusual large-trade alert for a trading bot
“Every 5 minutes, grab the last 5 minutes of dYdX whale flow from TradeSonar with up to 50 events and alert me if any single address moves more than $500k in one direction.”
Post-market session whale activity review
“Give me a full 4-hour lookback of whale flow events on dYdX from TradeSonar — up to 500 events — so I can review what smart money did during the US trading session today.”
Technical details
Endpoint
GEThttps://api.tradesonar.io/v1/whales/flow?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need raw, event-level whale order flow from dYdX on-chain data with address attribution and classification — as opposed to aggregated long/short ratios (use the crowding endpoint), funding data (use the funding endpoint), or candlestick OHLCV data. Best when you need to identify specific smart-money wallets, their trade direction, and exact USD sizing within a recent time window.
Side effects
- Invalid limit value outside 1-500 range returns validation error
- since_min exceeding 1440 returns parameter error
- Payment not included or insufficient USDC returns 402 Payment Required
- Replica lag or indexer downtime may cause stale data_as_of timestamps
- Empty events array returned if no whale-sized flow occurred in the requested window
