API registry / Exact Online

Exact Online

No vendor machine-readable spec. Exact publishes only HTML reference docs: https://start.exactonline.nl/docs/HlpRestAPIResources.aspx (per-endpoint detail pages HlpRestAPIResourcesDetails.aspx?name=...). API is OData v2-style but no public $metadata (requires auth). Same API serves exact-online-uk (start.exactonline.co.uk) and exact-online-nl (start.exactonline.nl).
