Capy Inc Authentication

Authentication

Lemin Captcha uses a two-key model. A public captcha_id (site key) identifies a configured captcha to the browser widget and is safe to expose client-side. A secret private_key authenticates the server-side verification call and must never be sent from the browser. The private_key is supplied in the JSON body of the verification request (not as an HTTP header), so it is not expressed as a standard OpenAPI securityScheme; the OpenAPI models it as a required request field. There is no OAuth surface.

Capy Inc. secures its APIs with apiKey across 2 declared security schemes, as derived from its OpenAPI definitions.
