# API Keys and credits

You can check the status and the number of credits associated with your API key by calling the `checkKey` endpoint. 

This request is **not authenticated**, meaning you do not need to pass the `X-API-Key`header.

<pre class="language-javascript"><code class="lang-javascript"><strong>const BASE_URL = 'https://api.conblox.xyz/';
</strong>const endpoint = 'checkKey';
const API_KEY = "YOUR_API_KEY";
const response = await fetch(BASE_URL + endpoint, {
    method: 'POST',
    headers: {
        'Content-Type': 'application/json',
    },
    body: JSON.stringify({ 'apiKey': API_KEY }),
});

const data = await response.json();
</code></pre>

**Example Response:**

```json
{
    "apiKeyValid": true, 
    "data": {
        "credits": 503
    }
}
```

In the response:

* `"apiKeyValid"`: Boolean indicating if the API key is valid.
* `"credits"`: The number of credits associated with your API key.

For more information on the `checkKey` endpoint, check the [API reference](/docs/scam-address-api/api-reference.md).

## 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, and the optional `goal` query parameter:

```
GET https://conblox.gitbook.io/docs/scam-address-api/authentication/api-keys-and-credits.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
