### License Authorization Method

There are two types of product licenses based on how the client application authorizes itself to interact with a license:

* Key-based product licenses: client interactions with the license have to be authorized using a `license_key`
* User-based product licenses: the license has a corresponding "license user" instead of a license key. Client interactions with the license have to be authorized using a `username`

### Errors

If an error occurs, the response will have an HTTP status code of 400 or higher, and the response body will contain an error description in the following format:

:::CodeblockTabs

```typescript
{
  status: number,
  code: string,
  message: string
}
```

# 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://docs.licensespring.com/license-api/consumption/add-feature-consumption.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.
