Detect anomalies in time-series data — use after pulling numeric metrics from monitoring APIs, financial data sources, IoT sensors, or spreadsheet columns. Send a single numeric array and specify a window size. Early windows define 'normal', recent windows are tested for anomalies.
Typical workflow: (1) Pull a column of numbers from Sheets, a Supabase time-series table, or a metrics API. (2) Pass the array here. (3) Get back which time windows are anomalous.
Examples:
- Revenue monitoring: Pull monthly revenue from Sheets → detect anomalous months
- Stock screening: Pull 90 days of closing prices → find unusual price windows
- Server health: Pull response-time metrics → identify degradation windows
- Sensor QA: Pull temperature readings from IoT API → flag sensor drift
