Public JSON feed

Read-only snapshots, refreshed by cron every 6 minutes. All timestamps are UTC ISO 8601. Clients should poll at most once per minute and reject mixed generation_id values during updates.



demo=true identifies fictional preview data. UNKNOWN means insufficient feed coverage. NONE means no keyword signal, not a guarantee of safety. Daily changes use each provider’s daily baseline. Prices may be delayed and markets may be closed. UST10Y is a yield; its percentage change is relative, not basis points. Change bars show magnitude, not historical sparklines or causal correlation.
