How to search with Google API?

I would like to do a custom program that search on Google, I read there are APIs to do the queries, but Google is asking me a "website", I don't have a website, I 开发者_JAVA技巧only want to search on Google by a program that i'm developing in PHP (PHP_CLI).

How Can I use these APIs?

Not sure that you really mean, if you want to add Google Search into your HTML page, why don't you just create a form in which the action is pointed to Google Search?

<form method="get" action="http://www.google.com/search">
    <input type="text" name="q" size="31" maxlength="255" value="" />
    <input type="submit" value="Google Search" />
    <input type="radio"  name="sitesearch" value="" />The Web
    <input type="radio"  name="sitesearch" value="yourdomain.com" checked /> My Site
</form>
