About Scalar
Scalar's Agent Chat now asks before every API call and hides your saved keys.
Scalar ships several package lines on separate version tracks. The November 10 batch makes the API client's Agent Chat ask for approval before any AI-generated request, including GETs, and redacts saved credentials before responses reach the model. The API reference 1.78 renders Avro, RAML and Protobuf schemas in AsyncAPI messages, the ASP.NET Core integration adds multipart file controls and OpenID Connect defaults, and the mock server fixes decimal and nested-response bugs.
