International markets · official monthly data

API with individual key →

OECD · share prices · base 2015=100. Monthly country series, not daily S&P 500, SMI or Nikkei index levels. Changes compare published periods.

Batch requests with an individual key and JSON responses. Website display summaries remain public. Data comes from the Central Bank, CVM and official B3 COTAHIST files.

Stocks and ETFs use imported COTAHIST files. The 12 Brazilian indices use official B3 closing statistics. Distribution events continue to come from brapi. International monthly series come from the OECD; TradingView chart values are not redistributed through the API. No paid data service has been contracted. Updating B3 and CVM files requires running the synchronisation scripts; collection dates remain visible.
