  async function getTrending() {
    const data = await fetch('https://api.coingecko.com/api/v3/search/trending');
    return {
      coins: data.coins.map(c => ({
        name: c.item.name,
        symbol: c.item.symbol,
        market_cap_rank: c.item.market_cap_rank,
        price_btc: c.item.price_btc,
      })),
    };
  }

  {
    name: 'trending',

    inputSchema: { type: 'object', properties: {} }
  },

• index.js:332-333 (handler)
