To start, you'll need to ensure that you have an API key from Anthropic. This key is essential for authenticating your requests and can be obtained through the Anthropic web Console. With your API key in hand, you're ready to construct your API call.
A typical Claude API request for creating a message looks like this:
curl https://api.anthropic.com/v1/messages \
--header "x-api-key: YOUR_API_KEY" \
--header "content-type: application/json" \
--data \
'{
"model": "claude-3-opus-20240229",
"max_tokens": 1024,
"messages": [
{"role": "user", "content": "Hello, world"}
]
}'
In this request:
model field specifies the version of Claude you wish to use. It's important to choose the correct model for your task, as different models have various capabilities and limitations.max_tokens field sets the maximum number of tokens (pieces of text) that Claude will generate in its response. This limit helps control the length and computational cost of the response.messages field contains an array of message objects, representing the conversation history. Each message has a role (either "user" or "assistant") and a content field. The content can be a simple text string or a more complex structure for including images.Starting with Claude 3 models, you can also send images as part of your request:
{"role": "user", "content": [
{
"type": "image",
"source": {
"type": "base64",
"media_type": "image/jpeg",
"data": "BASE64_ENCODED_IMAGE_DATA"
}
},
{"type": "text", "text": "What is in this image?"}
]}
This functionality enables Claude to process and respond to visual information, opening up a wide range of applications for the API.
A successful API call will return a JSON object containing the generated message. The response includes several key pieces of information:
id: A unique identifier for the message.role: The conversational role of the generated message, which will always be "assistant" for responses.content: An array of content blocks generated by Claude, usually containing text.model: The model version that processed your request.stop_reason: Indicates why Claude stopped generating content. This could be due to reaching the end of a conversational turn, hitting the maximum token limit, or encountering a custom stop sequence.Example response:
{
"content": [{"type": "text", "text": "Hi! My name is Claude."}],
"id": "unique_message_id",
"model": "claude-3-opus-20240229",
"role": "assistant",
"stop_reason": "end_turn",
"usage": {
"input_tokens": 10,
"output_tokens": 25
}
}
For applications that require real-time interaction or large volumes of content, the Claude API supports streaming responses. This method uses server-sent events to incrementally deliver the response, allowing your application to process each piece of content as it's generated.
To enable streaming, add "stream": true to your request body:
{
"model": "claude-3-opus-20240229",
"messages": [{"role": "user", "content": "Hello"}],
"max_tokens": 256,
"stream": true
}
When streaming, you'll receive a series of events, including message_start, content_block_start, content_block_delta, and message_stop, allowing you to assemble the full response in real-time.
Making a Claude API call is a straightforward process that opens up a world of possibilities for integrating advanced AI into your applications.
