API Documentation
Extended API documentation hub for market data, trading integration, builder codes, fees and developer resources for programmatic access to Extended markets.
Developer Access
Extended exposes developer resources for market data and trading integrations. Use API documentation to understand available endpoints, request models, authentication requirements, market metadata and streaming data.
Market Data
The trading terminal can consume public market information such as prices, funding, open interest, volume, order books and candle data. Production integrations should follow documented rate limits and schema rather than relying on UI internals.
Trading and Builder Integrations
Programmatic trading and builder-code integrations can carry additional authentication and account requirements. Builder Codes can attach an approved per-order fee and work alongside referral relationships.
