Claude Code (using Anthropic Models)

You can follow these instructions to use your VERDE API Key after installing Claude Code. More information on using Claude Code can be found here, https://docs.anthropic.com/en/docs/intro.

Note

These instructions assume you are using a space that is connected to Anthropic models. If you need access to Claude Code using a non-Anthropic model, then use the instructions for Claude Code Router.

Prerequisites

  1. Your VERDE course or team must be configured to use Anthropic models (see instructor or team lead)
  2. Obtain your VERDE API Key. Instructions can be found here
  3. Install Claude Code. Instructions can be found here, https://www.anthropic.com/claude-code/
  4. The remaining instructions assume you have an open terminal on system with Claude Code and bash installed.

1. Setting up the necessary environment variables

This step should only be needed the first time you use Claude Code.

In a terminal, set the following environment variables and replace ANTHROPIC_API_KEY to your VERDE API Key. 

export ANTHROPIC_BASE_URL="https://llm-api.cyverse.ai"
export ANTHROPIC_API_KEY="insert-VERDE-API-Key-here"
export ANTHROPIC_MODEL="anthropic/claude-sonnet-4"
Note, the ANTHROPIC_MODEL can be set to any available Anthropic model. Information about available models can be found here, https://docs.anthropic.com/en/docs/about-claude/models/overview

2. Start Claude Code

You can then run Claude Code. 

claude
After initially launching Claude Code, claude will write the variables into a ~/.claude/settings.json file. You do not need to repeat step #1 again for future sessions.

If you need to change your ANTHROPIC_API_KEY

If for some reason you need to change your VERDE API Key, you can use the slash command /logout in claude or delete your ~/.claude/settings.json; then, repeat steps 1-2.
