Implementation Reference

• index.js:50-79 (handler)

  The generic `callTool` function that handles API requests for all tools, including `url_shorten`.

  async function callTool(endpoint, params) {
    const fetch = (await import('node-fetch')).default;
    const isGet = ['GET'].includes((TOOLS.find(t => t.endpoint === endpoint) || {}).method);
    
    const url = isGet 
      ? `${BASE_URL}${endpoint}?${new URLSearchParams(params)}`
      : `${BASE_URL}${endpoint}`;
    
    const res = await fetch(url, {
      method: isGet ? 'GET' : 'POST',
      headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${API_KEY}`,
      },
      body: isGet ? undefined : JSON.stringify(params),
    });
    
    const text = await res.text();
    let data;
    try { data = JSON.parse(text); } catch { data = { raw: text }; }
    
    if (!res.ok) {
      if (res.status === 402) {
        throw new Error(`Insufficient credits. Add credits at https://iteratools.com. Cost: ${TOOLS.find(t=>t.endpoint===endpoint)?.price || 'see docs'}`);
      }
      throw new Error(`API error ${res.status}: ${text.substring(0, 200)}`);
    }
    
    return data;
  }

• index.js:37-37 (registration)

  { name: 'url_shorten', description: 'Shorten a URL', inputSchema: { type: 'object', properties: { url: { type: 'string' } }, required: ['url'] }, endpoint: '/url/shorten', price: '$0.001' },
