/**
 * Performs scope 3 Spend based emission calculations by making a POST request to the economic activity API endpoint.
 * Supports optional attribution with revenue for proportional allocation.
 *
 * @export
 * @param {CommonRequest} payload - The request data to be sent to the API
 * @return {Promise<EmissionResponse | EmissionResponseWithDetails>} A promise that resolves to the emission calculation result. Returns EmissionResponseWithDetails if includeDetails is true, otherwise EmissionResponse
 * @throws {Error} May throw an error if the API request fails
 *
 * @example
 * // Basic economic activity request
 * const request = {
    "time": {
      "date": "2025-01-04"
    },
    "location": {
      "country": "usa"

      "unit": "usd"
    },
    "includeDetails": false
  };
 * const result = await calculate(request);
 *
 * @example
 * // Economic activity request with revenue attribution
 * const requestWithAttribution = {
