src/toolService.js:156-164 (handler)

Main handler function that executes the tool logic by calling the CoinGecko API service's getNetworks method and wrapping the response with standardized message, data, and summary.

async getCoinGeckoNetworks(page = 1) {
  const result = await this.coinGeckoApi.getNetworks(page);

  return {
    message: "CoinGecko networks retrieved successfully",
    data: result,
    summary: `Found ${result.data?.length || 0} networks on page ${page}`,
  };
}

  try {
    const queryParams = new URLSearchParams();
    if (page) queryParams.append('page', page);

    const url = `${this.baseUrl}/networks${queryParams.toString() ? '?' + queryParams.toString() : ''}`;
    
    const response = await fetch(url, {
      headers: {
        'x-cg-demo-api-key': this.apiKey
      }
    });
    
    if (!response.ok) {
      throw new Error(`HTTP ${response.status}: ${response.statusText}`);
    }
