Read AI REST API

Obtain this bearer access token through the Read AI OAuth 2.1 authorization-code flow described in API Keys & Authentication: first register a client at `https://api.read.ai/oauth/register`, then complete the browser flow at `https://api.read.ai/oauth/ui`, then exchange the code for tokens at the token endpoint shown in the docs. Tokens carry scopes such as meeting:read and mcp:execute; access tokens expire after about 10 minutes and must be refreshed with the rotating refresh token.
