You only change two environment variables — no need to rewrite call logic.

Step 1

Create an API key

Create a key for a team or project and set its quota.

Step 2

Set base URL and token

Export the env vars so Claude Code sends requests to LowCostAI.

Step 3

Run and check usage

Use claude normally; consumption is logged per key and model.

# Point to the LowCostAI endpoint
export ANTHROPIC_BASE_URL="https://api.lowcostaiapi.com"

$env:ANTHROPIC_BASE_URL = "https://api.lowcostaiapi.com"
$env:ANTHROPIC_AUTH_TOKEN = "YOUR_TOKEN"
