What you get#
Onekey exposes World Bank as 10 endpoints behind one API key: 2 endpoints return one record (data is an object) and 8 endpoints return a list (data is an array). Every answer uses the same envelope (success, data, metadata, error), the cost is reported in metadata.credits_charged, and fields are mapped onto the unified schema so the code you write for World Bank also works for the rest of the government & public data category.
