# How to configure the BetterToken OpenAI-compatible API in Cline

> Enter the correct Cline provider, Base URL, API Key, and Model ID for BetterToken, then verify the connection and fix common errors.

## Direct answer

In Cline, select **OpenAI Compatible**, set **Base URL** to `https://www.bettertoken.ai/v1`, paste your BetterToken API Key, and enter a Model ID from the **GPT Key group**. Do not use the Anthropic-compatible address for Claude Code, and do not select the official **OpenAI** provider.

| Cline field  | BetterToken value                                                                                           |
| ------------ | ----------------------------------------------------------------------------------------------------------- |
| API Provider | `OpenAI Compatible`                                                                                         |
| Base URL     | `https://www.bettertoken.ai/v1`                                                                             |
| API Key      | Your BetterToken API Key                                                                                    |
| Model ID     | A model ID from the **GPT Key group** in the <a href={"https://www.bettertoken.ai/pricing"}>model plaza</a> |

<Info>
  This FAQ focuses on the values for each field and connection troubleshooting. If you need to start with installation, follow the [complete Cline setup guide](/en/ai-tools/cline).
</Info>

## Complete setup

<Steps>
  <Step title="Prepare the API Key and Model ID">
    Create an API Key, then copy a currently available Model ID from the **GPT Key group** in the <a href={"https://www.bettertoken.ai/pricing"}>model plaza</a>. Enter the ID exactly as shown instead of using the marketing display name.
  </Step>

  <Step title="Open Cline settings">
    Open the Cline panel in VS Code and click the gear icon.
  </Step>

  <Step title="Select OpenAI Compatible">
    Under **API Provider**, select **OpenAI Compatible**. This provider connects Cline to a third-party OpenAI-compatible endpoint.
  </Step>

  <Step title="Enter the four required values">
    Fill in Provider, Base URL, API Key, and Model ID using the table above. The Base URL must include `/v1`.

    If **Use Azure Identity Authentication** appears, leave it disabled. BetterToken authenticates with an API Key, not Azure Identity.
  </Step>

  <Step title="Verify the connection">
    Click **Verify** in Cline. After verification succeeds, create a task and send a simple prompt to confirm that the model responds and tool calls work.
  </Step>
</Steps>

## Which advanced fields should you change?

Cline may also show Context Window, Max Output Tokens, Image Support, or Computer Use. Keep the defaults for the first connection. Change a field only when the model plaza or model documentation confirms the relevant capability and limit.

Model prices can change. Do not rely on a fixed price saved in local Cline settings; check the current model and price in the <a href={"https://www.bettertoken.ai/pricing"}>model plaza</a>.

## Common errors

| Symptom                         | Check first                                                    | Fix                                                                                           |
| ------------------------------- | -------------------------------------------------------------- | --------------------------------------------------------------------------------------------- |
| `Invalid API Key` or `401`      | Whether the Key is complete and belongs to the current account | Copy the Key again, remove surrounding spaces, and do not mix it with an official OpenAI Key  |
| `Model Not Found`               | Whether the Model ID belongs to the GPT Key group              | Copy an available ID from the model plaza without changing its case or suffix                 |
| `404` or endpoint not found     | Whether `/v1` is missing                                       | Use `https://www.bettertoken.ai/v1`, not the Anthropic-compatible Claude Code address         |
| Connection timeout              | Local network, firewall, or stale proxy settings               | Confirm BetterToken opens in your browser, disable an invalid proxy, and run **Verify** again |
| Old configuration still applies | The Cline session has not refreshed                            | Save the settings, reopen Cline, or run **Developer: Reload Window**                          |

## Where this setup applies

These values connect Cline to **GPT Key group** models through the BetterToken OpenAI-compatible endpoint. They do not change Cline Rules, Memory Bank, MCP, or local tool permissions.

For Claude Code, use the Anthropic-compatible address without `/v1` and follow the [Claude Code setup guide](/en/ai-tools/claude-code).
