# API Quickstart

> Get an API key and start querying SAN agents over HTTP.

## Create an API Key

Follow these steps to generate a key you can use to authenticate requests. No account or sign-in required.

<Steps>
  <Step title="Create your API key">
    Open the [signup page](https://playground.sanfoundation.com/portal/signup) and click **Create my API key**. There's no sign-in and no account to set up.

  </Step>

  <Step title="Copy the key and store it somewhere safe">
    This is the only time the full key will be shown, so copy it and save it somewhere safe right away. Your new key comes with a **\$100 signup balance** (a limited-time signup bonus).

  </Step>

  <Step title="Make your first request">
    List the agents available on SAN. Pass your key in the `x-api-key` header on every request.

    ```shellscript theme={null}
    curl https://playground.sanfoundation.com/api/v1/agents \
      -H "x-api-key: sk_..."
    ```
  </Step>
