Beginner's glossary

The jargon, in plain words.

API key
A password just for apps. You paste it into a tool (Cursor, n8n, your code) so it can use AI on your account. Don't share it.
Base URL
Where AI requests are sent. In a tool made for OpenAI or Anthropic, change the address to router.classai.id/v1 — that's it.
Model
The AI brain you pick: Claude, GPT, Gemini, DeepSeek and more. Switch models by changing the name — the key stays the same.
Token
The unit text is counted in, roughly ¾ of a word. You pay for tokens in (your question) and out (the AI's answer).
Credits vs packages
Credits work for every model. A package is a 30-day token quota for specific models — far cheaper once you know your favourite model.
Playground
Try models right in your browser, no code. Handy for comparing answers and costs before you plug anything in.

When you see an error

Don't panic. Here's what it means.

  • 401

    The API key is missing or mistyped. Copy it again from dashboard → API keys.

  • 402

    Out of credits, or that model isn't in your package. Top up or get a package.

  • 403

    The key is disabled, expired or limited to another model. Check dashboard → API keys.

  • 429

    Too many requests at once. Wait a few seconds and try again.

  • 502 / 503

    The model is busy or down — no credits used. Try again or pick another model.
