Cboe Authentication
Authentication profile for the Cboe LiveVol All Access API. All API access is OAuth 2.0 against the Cboe LiveVol IdentityServer at id.livevol.com, which publishes a full OpenID Connect discovery document (saved at well-known/cboe-openid-configuration.json). Machine-to-machine access uses the client_credentials grant; browser-based applications use the authorization_code flow. Access tokens are bearer tokens sent in the Authorization header and expire after 3600 seconds; refresh tokens are supported. The public Cboe Delayed Quotes JSON endpoints on cdn.cboe.com require no authentication.
Cboe Global Markets secures its APIs with oauth2 and openIdConnect across 2 declared security schemes, as derived from its OpenAPI definitions. OAuth 2.0 is offered via the clientCredentials, authorizationCode, password, refreshToken, and implicit flow(s).
