Black Knight (Acquired by ICE — Now ICE Mortgage Technology)

Optimal Blue Product & Pricing APIs (divested to Constellation)

Optimal Blue's Product & Pricing Engine (PPE) generates eligible products and pricing for any user in any format and automates loan creation, locking, post-lock management, and secondary / lock-desk workflows. Originally acquired by Black Knight in 2020, Optimal Blue was divested to Constellation Software's Perseus Operating Group in September 2023 as a condition of FTC clearance for the ICE / Black Knight deal. APIs now live at digitalmarketplace.optimalblue.com under OAuth 2.0, with claimed search-request averages under 1 second across "millions of calls daily."
