Authentication

LEAPERone uses separate credentials for model traffic and account control-plane operations.

Base URL

https://api.leaper.one

Model API Keys (sk-)

Use an API key for OpenAI-compatible model endpoints under /v1/*. Pass it in the Authorization header:

curl https://api.leaper.one/v1/chat/completions \
  -H "Authorization: Bearer sk-your-api-key" \
  -H "Content-Type: application/json" \
  -d '{"model":"auto","messages":[{"role":"user","content":"Hello"}]}'

X-API-Key Header

Alternatively, use the X-API-Key header:

curl https://api.leaper.one/v1/chat/completions \
  -H "X-API-Key: sk-your-api-key" \
  -H "Content-Type: application/json" \
  -d '{"model":"auto","messages":[{"role":"user","content":"Hello"}]}'

Control Tokens (lpc_)

CLI, EnvX, account automation, usage queries, tickets, and organization operations use scoped control tokens under /api/v1/*. Sign in through the Dashboard authorization UI:

npx @leaperone/cli auth login
npx @leaperone/cli auth status

Control tokens carry explicit scopes such as api_keys:read, credits:read, usage:read, or envx:write. Do not use a model API key as a permanent substitute for a control token.

Creating API Keys

You can create and manage keys in two ways:

Dashboard — go to Settings > API Keys and click Create Key.

CLI — list your existing keys from the terminal:

npx @leaperone/cli apikey list
