UK Contracts Finder OCDS API

Contracts Finder covers government and agency opportunities and past contracts, principally for England and non-devolved bodies; Scotland, Wales and Northern Ireland have separate procurement sites. The OCDS search filters ISO 8601 publication dates and planning, tender, award or implementation stages, returning at most 100 releases per cursor page; a current-day CSV is also available.
