Buy this if you need to: (a) resolve a Japanese business day / T+N settlement or invoice due date — today's bank & TSE calendar with T+1..T+20 already computed, including the Dec 31-Jan 3 closure that the official holiday source omits (?types=jp-business-day); (b) value something in a population-weighted unit of account at today's ECB FX, byte-for-byte reproducible (?types=openunit); (c) pick a local-LLM backend from a measured equivalence matrix (?types=llm-equivalence). Also: JP-equity event-cohort membership data (point-in-time; not a trading signal), AI provenance/trust artifact pack, governed-AI spending benchmarks. Multi-category (?types=), delta delivery, signed receipts, free preview."
