We have begun a two-step migration in the /match API response format that affects users relying on the features and matcher fields.

1. The matcher field in /match responses will be removed after February 27, 2026. Equivalent information is available via the /algorithms route (free to use).

2. A new explanations field has been added that is a strict superset of features. In addition to the partial scores produced by each component of the matching system, it includes textual descriptions of the matching decisions from each of these subsystems. These descriptions are designed for display in analyst workbenches or can be passed to generative AI tools to help interpret screening alerts. The features field will be removed after February 27, 2026. Users should update their applications to consume explanations before this date.
