Output
Returns a list of analyzed trading pairs with their robust z-scores, anomaly flags indicating whether volume deviates significantly from the baseline window, and the list of watched pairs the service currently tracks for the chosen exchange.
Example use cases
Whale alert monitoring for DeFi trader
“Scan Binance for volume anomalies on BTC/USDT, ETH/USDT, and SOL/USDT over the past 4 hours with strict sensitivity — I want to catch any sudden volume surges that might indicate whale activity.”
Exchange comparison for market analyst
“Run a volume anomaly check on Kraken for BTC/USD and ETH/USD over the last 7 days using normal sensitivity — I'm trying to see if anything unusual happened this week compared to baseline.”
Low-cap coin unusual activity scan
“Check for volume anomalies on OKX for DOGE/USDT and SHIB/USDT over the last 1 hour with wide sensitivity — I want to know if there's any early sign of a pump or unusual move.”
Technical details
Endpoint
POSThttps://markt.netzhandwerker.de/anomaly/volumeWhen to prefer
Choose this endpoint when you need a statistically rigorous, ready-to-use volume anomaly signal for cryptocurrency pairs without building your own baseline logic. It is particularly suited for agents that need to act on volume spikes or drops in near-real-time across major exchanges. Prefer it over raw OHLCV feeds when you want an already-computed robust z-score rather than raw candle data.
Side effects
- Requested trading pair not in the collector's watched_pairs list — returns empty or error for that symbol
- Exchange not supported — must be one of binance, coinbase, kraken, okx, bybit
- Invalid symbol format — must match BASE/QUOTE pattern like BTC/USDT
- Payment failure via x402 / insufficient USDC balance — request rejected with 402
- Lookback window with insufficient data — z-score may be unreliable or unavailable
