Cline setup

Cline is an autonomous coding agent for VS Code. It supports any OpenAI-compatible API, so it works with Claudech without plugins or proxies.

Before you start#

A Claudech API key from API keys. API access unlocks after your first purchase.
A model id from Models, for example claude-opus-5-5.

Settings#

Open the Cline panel, click the settings icon and fill in:

Setting	Value
API Provider	OpenAI Compatible
Base URL	`https://api.claudech.com/v1`
API Key	your `sk-...` key
Model ID	`claude-opus-5-5` (or any Claudech model id)

Under the model configuration, set the context window to 1000000 and turn on image support; every Claudech model accepts images. Save, then give Cline a task.

Anthropic format works too

Cline's Anthropic provider also works: tick the option to use a custom base URL and enter https://api.claudech.com (without /v1). Billing is identical either way.

Choosing a model#

claude-fable-5-1 for long, multi-step tasks where quality matters most.
claude-opus-5-5 as a fast everyday default.
claude-opus-5 for hard debugging; it thinks longer before answering.

Every model is billed per token from your balance; agent sessions resend context on each step, and the repeated part is billed at the cheaper cached-input rate automatically.

Troubleshooting#

Symptom	Fix
`401` or "invalid API key"	Re-copy the key without spaces; check it is active under API keys
`404 model_not_found`	Use the Claudech model id exactly, with no vendor prefix
"Verification failed"	The base URL must be exactly `https://api.claudech.com/v1` with no trailing slash
`402 insufficient_balance`	Top up under Billing
