Engine by MoneyLion, formerly Even Financial, runs a public REST API with self-serve docs covering leads, rate tables, offer previews, and analytics. Auth is bearer tokens in publishable, confidential, and experimental flavors. No webhooks or sandbox are documented; polling is the pattern.

Auth is bearer tokens in publishable, confidential, and experimental flavors. No webhooks or sandbox are documented; polling is the pattern.
Even Financial has a workable official integration path. Most engineering teams can build against it directly. Open API: self-serve, documented, with SDKs
Even Financial is an embedded-finance marketplace platform founded in 2014 by Phillip Rosen in New York City.

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.
