Market Identifier Code (ISO 10383) + is-open-now API

Resolve an ISO 10383 MIC to its exchange name, operating MIC, country, city, IANA timezone, and regular trading hours, then compute whether the market is OPEN RIGHT NOW (timezone + weekday aware). The MORE: a curated MIC table joined with a live open/closed calculation an LLM can't do. Answers 'what exchange is MIC XNYS', 'is the LSE open now', 'trading hours for Tokyo Stock Exchange', 'timezone of this market code'.
