Z-Score & IQR Outlier Detector

Choose this endpoint when you need dual-method statistical outlier detection (Z-score and IQR together) on a simple numeric series without setting up a local stats library. Ideal for quick data quality checks, pre-processing pipelines, or validating experiment results in an agentic workflow where a $0.01/call micro-payment is acceptable.

• Missing or malformed 'series' query parameter returns an error
• Non-numeric characters in the series cause a parse error
• Too few data points (fewer than 3-4) may produce unreliable or error results
• Empty series input returns an error
• Payment failure or 402 response if x402 payment is not properly handled
