调用 API

1

设置您的 API 密钥

从 Anthropic 控制台 获取您的 API 密钥并将其设置为环境变量：
export ANTHROPIC_API_KEY='your-api-key-here'
2

进行您的第一次 API 调用

运行此命令来创建一个简单的网络搜索助手：
curl https://api.anthropic.com/v1/messages \
  -H "Content-Type: application/json" \
  -H "x-api-key: $ANTHROPIC_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -d '{
    "model": "claude-sonnet-4-20250514",
    "max_tokens": 1000,
    "messages": [
      {
        "role": "user", 
        "content": "What should I search for to find the latest developments in renewable energy?"
      }
    ]
  }'
示例输出：
