Solution
OSM “planet” filesRequesting large amounts of data from API can place undue load onthe OSM serverAPI is really designed for adding and editing data, not retrievingSo OSM also makes its data available as downloadable “planet” files inOSM XML format, containing OSM data for the entire planetWhole planet too large for most to use directly, so country or regionalextracts available (eg. )Geofabrik
OSM planet is hugeThe complete OSM DataLatest Weekly Planet File: 33 GBLatest Weekly Changesets: 782 MB
