# Sandbox

The Endole API provides a sandbox environment that allows you to test requests and build integrations without consuming credits or affecting live data.

## Usage

To make requests in the Sandbox environment, you must create a dedicated **Sandbox API Key** via your [API dashboard](https://app.endole.co.uk/api). Sandbox keys are 64-character strings prefixed with `sandbox_`.

Pass your Sandbox API key using the standard authentication header just like a live key.

Requests authenticated with a sandbox key return mock data matching the standard response structure and consume **0 credits**.

## Example Request

```shellscript theme={null}
curl -X GET "https://api.endole.co.uk/company/01234567/financials" \
     -H "Authorization: Bearer sandbox_ca6e9ce3f70b13a4e13d9cf9e451411f1f2140d21e8e5531cd37fec"
```
