What you get#
Onekey exposes USAspending as 8 endpoints behind one API key: 1 endpoint return one record (data is an object) and 7 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 USAspending also works for the rest of the government & public data category.

These unified fields come back from USAspending, with the same names as on every other platform. The count is how many of its 8 mapped endpoints return the field; a field the source lacks is null, never missing. 11 platform-specific fields (ext.<name>) come on top, documented on each endpoint page.
