## TL;DR

An international key goes with https://dashscope-intl.aliyuncs.com/compatible-mode and a Beijing key with https://dashscope.aliyuncs.com/compatible-mode.

## The error

```text
match the API key region to the base URL or get 401 Invalid API-key
```

## Fix

1. An international key goes with https://dashscope-intl.aliyuncs.com/compatible-mode and a Beijing key with https://dashscope.aliyuncs.com/compatible-mode.
   Expected: you can confirm this matches your situation.
2. Re-run the original operation and confirm the error is gone.
   Expected: no error, normal output.

## When to use

- You hit this exact error with DashScope.
- The symptom matches: match the API key region to the base URL or get 401 Invalid API-key.

## When NOT to use

- A different error message from DashScope; the cause here is specific to this error.
- Unrelated DashScope issues (different feature, different failure).
- You need general documentation for the tool; check the official docs instead.

## Variant phrasings

### match the API key region to the base URL or get 401 Invalid API-key

## Why it happens

Alibaba Cloud Model Studio has separate regional endpoints. A key from one region used against another region's URL fails auth.

## Edge cases

- If your error message differs even slightly, this is probably a different issue; search the exact text.
- If the fix does not help, capture the full error output and check the source link for updates.
