Authentication

All REST endpoints authenticate with a Renesis API key (prefix ak_), passed in the X-API-Key header. Create and manage keys from your user page in the dashboard; the secret is shown only once at creation, so copy it then.

export API_KEY="ak_xxxxxxxxxxxxxxxxxxxx"

curl -H "X-API-Key: $API_KEY" \
  "https://api.renesis.fi/order-execution/execution/balance?exchange_account_id=your-account"

The key works on every route until you revoke it, with no login or session to keep alive. If a key was issued with a path allowlist, it must include the /order-execution prefix to call OEMS endpoints. Keep keys secret and server-side.

Daily Trading Limits

To prevent accidental large trades during development, each exchange account has a daily trading limit (default: $100/day). Check your remaining limit:

curl -H "X-API-Key: $API_KEY" \
  "https://api.renesis.fi/order-execution/execution/daily-limit?exchange_account_id=your-account"

All OEMS endpoints are served under the /order-execution prefix. For other environments, contact your administrator.
