Get Started with Anthropic

Quickstart Guide: Anthropic

This guide provides steps to get started with integrating Anthropic's API using JavaScript or Python. These instructions will help you install necessary packages, set up the API client, and utilize the Messages API for generating text responses.

Install Dependency

Before you can use the Anthropic API, you need to install the appropriate SDK.

JavaScript

To install the Anthropic SDK for JavaScript, use npm:

npm install @anthropic-ai/sdk

Python

To install the Anthropic SDK for Python, use pip:

pip install anthropic

Import and Configure Client

Configure your API client by importing the Anthropic SDK and setting it up with your API key and base URL.

JavaScript

import Anthropic from '@anthropic-ai/sdk';
const client = new Anthropic({
  baseURL: "BaseUrl",
  apiKey: "ApiKey",
});

Python

from anthropic import Anthropic
client = Anthropic(
    base_url="BaseUrl",
    api_key="ApiKey"
)

Using the Messages API

The Messages API allows you to generate text-based responses within a conversational context. You can specify a system persona and provide user inputs to guide the model's outputs.

JavaScript

const messages = await anthropic.messages.create({
  model: "claude-3-opus-20240229",
  max_tokens: 1024,
  system:
    "You are a poetic assistant, skilled in explaining complex programming concepts with creative flair.",
  messages: [{ 
	  role: "user", 
	  content: "Compose a poem that explains the concept of recursion in programming." }],
});

console.log(messages.content[0].text);

Python

messages = anthropic.Anthropic().messages.create(
    model="claude-3-opus-20240229",
    max_tokens=1024,
    system="You are a poetic assistant, skilled in explaining complex programming concepts with creative flair.",
    messages=[
        {"role": "user", "content": "Compose a poem that explains the concept of recursion in programming."}
    ]
)
print(messages.content[0].text)
