Developer documentation hướng dẫn cách thực hiện lệnh API đầu tiên với Claude và xây dựng ứng dụng assistant đơn giản.
Insight
Get started with Claude
Make your first API call to Claude and build a simple web search assistant.
Prerequisites
- An Anthropic Console account
- An API key
Call the API
```bash
export ANTHROPIC_API_KEY='your-api-key-here'
```
To persist the key across shell sessions, add the line to your shell profile (such as `~/.zshrc` or `~/.bashrc`).
</Step>
<Step title="Make your first API call">
Run this command to create a simple web search assistant:
```bash cURL
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 '{

"max_tokens": 1000,
"messages": [
{
"role": "user",
"content": "What should I search for to find the latest developments in renewable energy?"
}
]
}'
```

## Hành động
Bước 1: Lấy API key từ Claude Console và export thành biến môi trường ANTHROPIC_API_KEY. Thêm vào ~/.zshrc hoặc ~/.bashrc để lưu vĩnh viễn. Bước 2: Cài đặt SDK phù hợp với ngôn ngữ lập trình đang sử dụng. Bước 3: Tạo code với client.messages.create(), truyền model, max_tokens, và messages array. Bước 4: Chạy code và xem output. Với Python: python quickstart.py. Với TypeScript: npx tsx quickstart.ts. Với Java: gradle run hoặc mvn compile exec:java.
## Điều kiện áp dụng
