Failed to open stream with file_get_contents - can access it via endpoint in browser

Question

I'm trying to use Coinbase's REST API to get a list of available currencies:

You can see the JSON loads when you click the link above.

$coinbase_coins = file_get_contents('https://api.prime.coinbase.com/currencies');
$coinbase_coins = json_decode($coinbase_coins, true);

Now when I try to load it with file_get_contents, I get the error "failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request"

Why is it that I can access the endpoint via browser but now with file_get_contents?

Thanks ;)

Try setting a user-agent. That worked for me. See: https://stackoverflow.com/questions/30120211/php-file-get-contentsurl-turns-into-amp/30120589#30120589 — Thomas Park, May 16 '21 at 00:03

Could be your php runtime configuration. allow_url_fopen needs to be set to true.

Read about it here here in the manual.

I don't think so, because I'm also using the same structure for other REST API's endpoints without issue. – cpcdev Aug 28 '18 at 04:59
Is https required? Have you tried using http instead? – Nanobrain Aug 28 '18 at 05:01
I gave that a shot but no luck unfortunately. Appreciate your input anyway :) – cpcdev Aug 28 '18 at 05:03
If I were at my computer I'd try to duplicate the problem. – Nanobrain Aug 28 '18 at 05:04
probably because of https. have a look at this https://stackoverflow.com/questions/1975461/how-to-get-file-get-contents-to-work-with-https – Sayantan Das Aug 28 '18 at 05:06
Were you able to run their test? If so, what were there results for the https wrapper? As far as I understand, http wrapper is suppose to handle https as well. But my knowledge is limited here. – Nanobrain Aug 28 '18 at 05:15
From php.net Note: HTTPS is only supported when the openssl extension is enabled. Thats worth looking into – Nanobrain Aug 28 '18 at 05:19
The other Rest APIs im accessing all use https .. no issues using them. Ill look into it more today. – cpcdev Aug 28 '18 at 14:34
Very strange. Good luck. Ill try to duplicate the problem later myself. – Nanobrain Aug 28 '18 at 14:51
