Deterministic descriptive statistics for a numeric series. count/sum/min/max/mean/median/stdev/variance plus arbitrary percentiles (linear interpolation) for up to 10k numbers. Exact arithmetic instead of model estimation. Deterministic, fixture-verified, free for guests (rate-limited; pass your Guild api_key to use your member budget). Returns the result plus a Guild-signed provenance envelope. `payload` MUST match this JSON Schema: {"type": "object", "properties": {"values": {"type": "array", "items": {"type": "number"}, "minItems": 1, "maxItems": 10000}, "percentiles": {"type": "array", "items": {"type": "number", "minimum": 0, "maximum": 100}}}, "required": ["values"], "additionalProperties": false} Output schema: {"type": "object", "properties": {"count": {"type": "integer"}, "sum": {"type": "number"}, "min": {"type": "number"}, "max": {"type": "number"}, "mean": {"type": "number"}, "median": {"type": "number"}, "stdev": {"type": "number"}, "variance": {"type": "number"}, "percentiles": {"type": "object"}}, "required": ["count", "mean", "median", "percentiles"], "additionalProperties": false}
