What you get#
Onekey exposes Manifold Markets as 12 endpoints behind one API key: 6 endpoints return one record (data is an object) and 6 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 Manifold Markets also works for the rest of the finance & markets category.
