Black Knight API
ICE and Black Knight catalog substantial servicing APIs, from REST Servicing and MSP DX APIs to SOAP web services and bulk extracts, but everything is partner-only. Access needs a signed integration agreement, per-product entitlements, and InterChange enrollment; docs sit behind logins.
Frequently asked questions
Black Knight scores F on the API Report Card. ICE and Black Knight catalog substantial servicing APIs, from REST Servicing and MSP DX APIs to SOAP web services and bulk extracts, but everything is partner-only. Access needs a signed integration agreement, per-product entitlements, and InterChange enrollment; docs sit behind logins.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.

Extremely deep and high-stakes.
MSP's lineage traces back to the LPS / Fidelity / Alltel / DBA Systems mortgage servicing system that dates to the 1970s-1980s mainframe era and was the foundation of what became Fidelity National Information Services' mortgage business, spun out as Lender Processing Services (LPS) in 2008, taken private, and re-emerged as Black Knight Financial Services in 2014 with an IPO.
Developer portal documentation is behind authenticated login; non-partners cannot evaluate API capabilities, payloads, auth flows, or rate limits without first being approved as an MSP/Encompass partner. Black Knight's BKI Digital developer subdomain (developer.bkidigital.com) is intermittently unreachable from public DNS / refuses connections externally, suggesting either IP allowlisting or partner-VPN gating on the developer infrastructure itself.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
