CorvusLLM Quickstart - Buy, Paste, Test and Verify

Step 1: copy the values you actually need

After payment confirmation, CorvusLLM shows the delivered key on the website and also sends it by email. You do not need to wait for manual stock or inventory assignment.

Value	Use this	Where it is used
Customer API key	Your delivered CorvusLLM key	Authentication for every environment and dashboard login by key.
OpenAI-compatible base URL	`https://base.corvusllm.com/v1`	SDKs, raw HTTP, ChatBox, Open WebUI, n8n, and most custom tools.
Anthropic-native base URL	`https://base.corvusllm.com/anthropic`	Claude Code and other Anthropic-native tools.

Step 2: send one clean test request

Start with a short OpenAI-compatible request. This is the fastest way to confirm the key, the host, and your remaining balance.

curl quickstart

curl https://base.corvusllm.com/v1/chat/completions ^
  -H "Authorization: Bearer YOUR_CORVUSLLM_KEY" ^
  -H "Content-Type: application/json" ^
  -d "{\"model\":\"gpt-5.5\",\"messages\":[{\"role\":\"user\",\"content\":\"Say quickstart-ok\"}]}"

Step 3: if you use Claude Code, switch to the Anthropic path

Claude Code is the one major environment that should not start on /v1. It should start on the Anthropic-native path.

PowerShell

$env:ANTHROPIC_BASE_URL="https://base.corvusllm.com/anthropic"
$env:ANTHROPIC_AUTH_TOKEN="YOUR_CORVUSLLM_KEY"
$env:ANTHROPIC_MODEL="claude-opus-4-7"
claude

Step 4: log into the dashboard and check the same key

The same customer key you use for requests can also be used to sign into the personal dashboard. Customers can also keep using Google, GitHub, or email link login.

Open Personal Dashboard.
Use the delivered CorvusLLM key to log in.
Check the current balance, request count, recent requests, and model breakdown.

Step 5: know what happens at zero balance
