# List Lookup

> The List lookup endpoints let you retrieve information about Lists. Reference for the X API v2 standard tier covering list lookup.

export const Button = ({href, children}) => {
  return <div className="not-prose group">
    <a href={href}>
      <button className="flex items-center space-x-2.5 py-1 px-4 bg-primary-dark dark:bg-white text-white dark:text-gray-950 rounded-full group-hover:opacity-[0.9] font-medium">
        <span>
          {children}
        </span>
        <svg width="3" height="24" viewBox="0 -9 3 24" class="h-6 rotate-0 overflow-visible"><path d="M0 0L3 3L0 6" fill="none" stroke="currentColor" stroke-width="1.5" stroke-linecap="round"></path></svg>
      </button>
    </a>
  </div>;
};
