The HyperRail API enables partners to integrate digital asset infrastructure directly into their applications, including fiat on-ramp, off-ramp, and currency exchange operations. The API is designed using RESTful principles, providing predictable endpoints, standard HTTP methods, and structured responses to ensure a smooth developer experience.

​
API Design Principles

You can expect the following when working with the HyperRail API:
  • Resource-Oriented Endpoints Clear and intuitive URLs representing core resources.
  • Standard HTTP Methods & Status Codes Uses GET, POST, PUT, and DELETE with conventional response codes.
  • JSON Request & Response Format All responses are returned in JSON for easy parsing and integration.
  • Consistent Content-Type Handling
    All requests should include the header Content-Type: application/json.

​
Authentication

All API requests require authentication using your API keys. These keys identify your application and determine whether requests are processed in test or live mode. You can find and manage your API keys from the API Keys & Webhooks section of your HyperRail dashboard. Each endpoint includes examples showing how to properly authenticate requests.
