# Errors

**Padiwise** uses standard **HTTP response codes** to indicate the success or failure of an API request. Here's a general breakdown:

* **2xx codes** indicate a **successful** request.
* **4xx codes** indicate a **client-side error**—usually due to invalid input or missing parameters (e.g., a required field was not provided).
* **5xx codes** indicate a **server-side error** on **Padiwise's** end (these are rare but may occur during unexpected server issues).

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://padiwise.gitbook.io/padiwise/errors.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
