Key takeaways

  • Base URL https://api.luv13.ai/v1; send your key as Authorization: Bearer.
  • Keys start with sk-luv13- and are shown once.
  • Every model costs $0.33 per 1M tokens, input priced the same as output.

luv13 is an OpenAI-compatible API for open-weight models at base URL https://api.luv13.ai/v1; sign in at https://dash.luv13.ai/, create a key (it starts with sk-luv13- and is shown once), and send it as Authorization: Bearer <key>. Every model costs $0.33 per 1M tokens, input priced the same as output, so 800k input + 200k output = 1.0M tokens = $0.33.

Step 01

Get a key

In the dashboard, create a key. The full key starts with sk-luv13- and is shown once, at creation. Put it in an environment variable, never in client-side code.
