🌐API Structure & Base URL

All interactions with the Nansen API occur via HTTPS requests to specific endpoints. The general structure of an API call is:

HTTP Method + Base URL + Endpoint Path
  • HTTP Method: Primarily POST for retrieving data.

  • Base URL: The root URL for all API requests is:

    https://api.nansen.ai/api/beta
  • Endpoint Path: The specific path identifying the resource and desired data, appended directly to the Base URL (e.g., /smart-money/inflows). Endpoint paths for specific resources are detailed within their respective sections of this documentation.

  • Request Body: Parameters are typically passed in JSON format within the request body for POST requests. For example:

    {
      "parameters": {
        "smFilter": ["180D Smart Trader", "Fund", "Smart Trader"],
        "chains": ["ethereum", "solana"],
        "includeStablecoin": true,
        "includeNativeTokens": true,
        "excludeSmFilter": []
      }
    }
