Keys and Accounts

Reviewed by Proof · Updated

Definition

A luv13 account is where you create API keys, which start with sk-luv13-, and hold the prepaid credit that your requests spend.

Key takeaways

  • You sign in to the dashboard with Google or email and create a key there.
  • A luv13 key starts with sk-luv13-. The full key is shown once, when you create it, so copy it right away.
  • The account is prepaid: you top up credit in USD by card, from $5, and usage draws down the balance. There's no subscription.
  • Send the key in the Authorization: Bearer header on every chat completion request.
  • If you can't use the dashboard, email [email protected]. All of the above is from luv13.ai/docs and luv13.ai/pricing, checked on 2026-09-30.

Where the key goes

Keep it in an environment variable, as luv13.ai/docs does:

export LUV13_API_KEY=sk-luv13-...

Then send it as a Bearer token:

curl https://api.luv13.ai/v1/chat/completions \
  -H "Authorization: Bearer $LUV13_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "luv13/glm-5.3-flash", "messages": [{"role": "user", "content": "ping"}]}'

In a tool or SDK, paste it into the API key setting and set the base URL to https://api.luv13.ai/v1.

A missing or wrong key returns HTTP 401 with "type": "invalid_auth". See Errors and Status Codes.
