A Vendor-Supplied API (Application Programming Interface) is a set of defined protocols, routines, and tools provided by a third-party service provider to allow client applications to interact with their software or data. In the crypto domain, institutional trading platforms utilize vendor APIs to access market data feeds, execute trades on external exchanges, or integrate with specialized services like custody solutions, RFQ liquidity pools, or options pricing models.
Mechanism
The operational logic involves a client application sending requests to the vendor’s API endpoint, typically via HTTP/S or WebSocket protocols, formatted according to the vendor’s specifications. The API processes the request, performs the required operation on the vendor’s system, and returns a structured response. Authentication and authorization mechanisms, such as API keys or OAuth, control access to the vendor’s services.
Methodology
The strategic approach involves leveraging external capabilities to accelerate development, reduce operational overhead, and access specialized functionality without building it in-house. Principles include evaluating API reliability, security, documentation, and performance, ensuring proper error handling and retry logic, and managing API versioning. Relying on robust vendor-supplied APIs is critical for building scalable and feature-rich institutional crypto trading systems that integrate diverse market functionalities.
