# Quickstart

> Authenticate and read usage for your proxy credentials.

Make your first read-only API request with your organization API key. You can use the same key across proxy products.

**1. Get your API key**

An organization administrator creates the key in the dashboard. Store it in an environment variable:

```bash theme={null}
export DOUBLEDATA_API_KEY="your_api_key"
```

**2. Read proxy usage**

This returns workspace totals and per-credential usage for the current UTC month.

```bash theme={null}
curl --request GET \
  --url https://app.proxy.doubledata.com/api/v1/usage \
  --header "Authorization: Bearer ${DOUBLEDATA_API_KEY}"
```

**3. Choose your product**

Use [Residential](https://doubledata.mintlify.site/api-reference/residential.md), [Datacenter](https://doubledata.mintlify.site/api-reference/datacenter.md), or [Mobile](https://doubledata.mintlify.site/api-reference/mobile.md) for gateway connection parameters. Use [ISP](https://doubledata.mintlify.site/api-reference/isp.md) for Static ISP purchasing and subscription management.

The usage response reports bandwidth in bytes, request counts, and wallet usage charges in USD cents. Static subscriptions use separate subscription records. [Usage reference](https://doubledata.mintlify.site/api-reference/usage.md).

To send traffic through a proxy, use your proxy username and password with a gateway or assigned Static ISP connection. [Connection formats](https://doubledata.mintlify.site/guides/proxy-formats.md).
