Cline, Roo Code, Kilo Code

All three extensions have an OpenAI Compatible provider with the same fields. The menus can move a little between versions, but the four fields stay the same.

Steps

1. Open the extension’s panel in VS Code, then open its Settings (the gear icon).

2. Under API Provider, choose OpenAI Compatible.

3. Fill in:

   Field	Value
   Base URL	https://api.vikey.ai/v1
   API Key	Your Vikey API key
   Model ID	For example vikey/agent-coding, anthropic/claude-sonnet-5.5 or deepseek/deepseek-v4.1-flash

4. Save, then send a short message to check.

Model settings (optional)

Some versions show a Model Configuration section. Fill it in for the model you use:

Field	Suggestion
Context window	1000000 for the Claude, GPT and DeepSeek models on Vikey. Per-model numbers are on the pricing page.
Supports images	Turn on when the model has vision
Input and output price	Can stay empty. The real cost is always in the Usage menu of the Vikey dashboard.

Tip

These extensions resend the whole history and every tool result at each step. Vikey Auto trims old tool results that no longer matter, so long sessions in these extensions can cost noticeably less.

Common problems

What you see	Cause	Fix
404	Base URL without /v1, or /v1 written twice	Enter exactly https://api.vikey.ai/v1
Model '...' not found	A typo in the Model ID	Copy the id from the pricing page
402 Insufficient balance	No balance left	Top up
