  $context["content"] = "";

  // Loop through the 5 first results.
  $max = min( count( $data->items ), 5 );
  for ( $i = 0; $i < $max; $i++ ) {
    $result = $data->items[$i];

    $url = $result->link;

Thanks for solution

I feel like a dummy. I can't get it to work. I'm using WPCode to add snippets such as this code. Is that incorrect or is there something else I am doing wrong? Am I using the wrong ChatGPT model?

What I get is"

My capabilities are centered around providing information that was available up to that point, and I don't have access to live updates or the ability to browse the internet in real-time."

If I am not mistaken, this:

$content = "Title: $titlenExcerpt: $snippetnURL: $urlnn";

Was recently corrected to:

$content = "Title: $title\nExcerpt: $snippet\nURL: $url\n\n";

Is that true?
