1anthropic
library. You can do this via pip:
1 2bash pip install anthropic

Making Your First API Call

Now, let's dive into the juicy part: making an API call to the Claude-3-5-Sonnet model. The API uses the POST method to create messages. Here’s how you do it:

Python Code Example

```python import anthropic

Create an instance of the Anthropic API client

client = anthropic.Anthropic(api_key='your_api_key_here')

Define your messages as a list of dictionaries

messages = [ {"role": "user", "content": "Hello, Claude!"}, ]

Create a message sending it to Claude 3.5 Sonnet model

response = client.messages.create( model="claude-3-5-sonnet-20240620", messages=messages, max_tokens=150, )

Print the response

print(response) ```

Explanation of the Code

Import the Library: We start by importing the
1anthropic
module to access the API.
Instantiate the Client: An instance of
1Anthropic
is created with the provided API key, which you previously generated.
Define Your Messages: Here, you put in your conversation history. The API expects messages to be structured with roles (user/assistant) and content.
Create the Message: This is where you send your messages to the Claude-3-5-Sonnet model, specifying the number of tokens you’d like to receive in response.
Response Handling: Finally, we print the response received from the API, which would include the assistant's content.

Understanding API Parameters

When making calls to the Claude-3-5-Sonnet API, several parameters are essential for tailoring the request to your needs:

model: Specifies which model you’re using; in this case,
1claude-3-5-sonnet-20240620
.
messages: A structured list of input messages, alternating between the user and assistant roles.
max_tokens: The maximum number of tokens in the response.
temperature: Controls randomness in responses; setting it closer to 0 will yield more focused, deterministic output.
stop_sequences: Custom text sequences that will prompt the model to stop generating.
stream: Boolean for streaming the output incrementally (useful for real-time applications).

Make sure to review the API documentation for a full list of options.

Additional Use Cases

The Claude-3-5-Sonnet API can handle a myriad of use cases, including:
