Cline

A VS Code / Cursor extension that writes code on its own.

Three fields. Copy, don’t type

Do it in order. Don’t skip

1. Open VS Code (or Cursor), click Extensions on the left, search for Cline, press Install.

2. A Cline icon appears in the left bar — open it.

3. Click the gear icon in the top-right corner of the Cline panel.

4. API Provider: choose OpenAI Compatible. Not plain OpenAI and not Anthropic — those don't let you change the address.

5. Base URL: https://cheapai.lol/v1 — with the /v1 tail.

6. API Key: your key in full, including sk-.

7. Model ID: claude-opus-4.8 — paste it, don't type from memory.

8. Press Done and type “hi” in the Cline chat.

Check

If it didn’t start

• “401 / unauthorized / invalid api key” — the key was not copied whole. It starts with sk- and has no space at either end.
• “model not found” / “named models unavailable” / model in red — the name must match exactly: claude-opus-4.8. Not “Opus 5”, not opus, not claude-3, not gpt-4.
• The app shows no models — reopen its settings page: the model list is served from our address and appears once the Base URL and key are right.
• “Connection error” / spinner and silence — wrong Base URL. Almost every app wants the address with a /v1 tail.
• “/v1/v1” in the error — the app appends /v1 itself. Drop the tail, leave the site address.
• It replied, then stopped — you ran out of tokens. The balance is in your dashboard. Topping up on FunPay from the same nick lands on the same key.
