-### Local Ollama interface cannot be used
+### API (Ollama, etc.) Test Failure
 
-If encountering a 403 error, refer to: https://github.com/fishjar/kiss-translator/issues/174
+Common reasons for API test failures include:
+
+- Incorrect address:
+  - For example, `Ollama` has a native API address and an `Openai`-compatible address. This plugin currently supports the `Openai`-compatible address and does not support the `Ollama` native API address.
+- The default `Prompt` needs to support `JSON` output, but some AI models do not:
+  - This can be addressed by using `Hook` or a custom API.
+  - For details, refer to: [Custom API Example Documentation](https://github.com/fishjar/kiss-translator/blob/master/custom-api_v2.md)
+- Inconsistent parameters for some AI models
+  - For example, the parameters of the `Gemini` native API are highly inconsistent. Some model versions do not support certain parameters, leading to errors.
+  - In this case, you can modify the request body using a `Hook`, or replace it with `Gemini2` (an OpenAI-compatible address).
+- The server restricts cross-origin access, returning a 403 error:
+  - For example, `Ollama` requires adding the environment variable `OLLAMA_ORIGINS=*` when starting. See: https://github.com/fishjar/kiss-translator/issues/174
