Php – Yahoo Finance API file_get_contents 429 Too Many Requests

I am using Yahoo Finance’s API at https://query1.finance.yahoo.com/v8/finance/chart/Ticker with php’s file_get_contents and getting "failed to open stream: HTTP request failed! HTTP/1.0 429 Too Many Requests" but when I use curl to the same URL from the command line of the server I get an actual response! I verified that both of the requests are coming from the same IP.

I am not sending many requests – I sent maybe 40 get requests last night and then my first request today failed. My question is – has anyone seen the same type of problem? I read that the limit was 100 requests per hour – which I was well under!

Any advice would be appreciated.

    Since you noticed that curl works, try adding a user agent to your request to mimic curl.

    <?php

$url = "https://query1.finance.yahoo.com/v8/finance/chart/nvda"; 

$options = [
    'http' => [
        'method' => "GET",
        'header' => "User-Agent: curl/7.68.0rn"
    ]
];
$context = stream_context_create($options);
$response = file_get_contents($url, false, $context);

if ($response !== false) {
    echo "Response: " . $response;
} else {
    echo "Request failed";
}

?>

    I was running into the same issue in Rust and adding a similar user-agent to the request fixed it. You can also try a browser user agent such as Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/122.0.0.0 Safari/537.36.

    I have the same issue today with yahoo, but I get similar when I’m just browsing GitHub.

    On GitHub:

    Whoa there! You have exceeded a secondary rate limit.

    Please wait a few minutes before you try again; in some cases this may
    take up to an hour.

    On Yahoo:

    Call failed with status code 429 (Too Many Requests): GET
    https://query1.finance.yahoo.com/v8/finance/quote?symbols=EURILS%3DX&crumb=SryHRDouZx7
