ANTHROPIC API for R users

Tools to use the claude/anthropic LLM model's API from R.

Usage

Functions

The following functions are available in scripts/functions/anthropic.R:

• create_anthropic_body(message, model = "claude-3-7-sonnet-20250219", max_tokens = 1024): Creates the request body for the Anthropic API.
• send_anthropic_request(body, api_key = NULL): Sends a request to the Anthropic API using the specified model.

Here are some examples of how to use the functions:

Create Request Body

box::use(
    scripts/functions/anthropic[
        create_anthropic_body, 
        send_anthropic_request,
    ],
)

body <- create_anthropic_body("Provide a short answer: What's an API?", max_tokens = 50)
body

Send Request to Anthropic API

response <- send_anthropic_request(body)
print(response)

# > An API (Application Programming Interface) is a set of rules and protocols that allows different 
# software applications to communicate with each other. It defines the methods and data formats that 
# applications can use to request and exchange information.

Example Script

You can find an example script in scripts/drafts/test-api.R. This script demonstrates how to fetch exchange rate data from banks, process it, and send a request to the Anthropic API.

Environment Variables

Ensure you have the ANTHROPIC_API_KEY environment variable set in your .Renviron file:

ANTHROPIC_API_KEY="your_api_key_here"
