The enriched statistics (z-scores, percentile ranks, rolling averages) save downstream computation compared to fetching raw Fed data. ## Known failure modes - Invalid date format returns error — use YYYY-MM-DD - Requesting future dates returns no data or empty array - Unknown field names in 'fields' parameter may be silently ignored or cause errors - Missing payment (x402) returns 402 Payment Required - Very early historical dates may have no data if outside NFCI coverage window ## How this service works Chicago Fed composite index of 105 financial indicators covering money markets, debt, equity, and banking. Positive = tighter than average conditions, negative = looser. Weekly frequency, provides a single number summarizing broad financial conditions. Use for macro regime assessment and risk model inputs. ## Output Returns an array of weekly observations, each containing the NFCI composite value, month-over-month and year-over-year changes (absolute and percentage), z-scores relative to trailing 12 months and 5 years, percentile rank over 5 years, 3-month and 12-month rolling averages, and an above-trend binary flag. Positive values indicate tighter-than-average financial conditions; negative values indicate looser-than-average conditions. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http", "description": "Always \"http\" for HTTP endpoints" }, "method": { "enum": [ "GET", "HEAD", "DELETE" ], "type": "string", "description": "HTTP method.
