  title: Firstrade Unofficial Account API
  description: 'Community-reverse-engineered REST API for the Firstrade Securities brokerage platform (https://www.firstrade.com). This is NOT an official Firstrade API. Endpoints are discovered from network traffic analysis and are subject to change without notice. The base URL is the internal mobile/web gateway used by the Firstrade app. Authentication uses a session-based flow with cookie tokens (ftat, sid) obtained after login. All requests require the Accept-Encoding: gzip and access-token header values documented below. Source: MaxxRK/firstrade-api (MIT licence).'
