This is the name for a feature of the API dataset. They help make the contextual information that Wikimedia editors use to make their editorial decisions more understandable within an API feed. In other words, translating now two decades of editing behaviors into data. This feature is not filters, rankings, or value judgements of “good vs. bad edits”. Nor is it an AI making decisions about content accuracy, truth or quality. See our blog post about Credibility Signals for more explanation, and our Data Dictionary for all available credibility signals, labeled with a purple badge.
