Hey gys just started up a wordpress website for a club i am doing at school that deals with crypto currency. we currently have a couple of miners that are mining litecoins and bitcoins. on the wordpress site im looking to display the miner information through API calls through a widget on the main the page for instance i want to pull this information and display as a widget on the website. I was wondering if this even possible first off and how can it be accomplished i am currently pulling this information with c# programming. is there away to pull this through wordpress?

Yes — this is straightforward to do inside WordPress. Build a small plugin or native widget that uses the WordPress HTTP API to fetch the miner JSON, decode it in PHP, cache the result, and print only sanitized fields. That keeps load on the remote API low and avoids client-side CORS issues. Mention to : since you already have C# code, you can either let WordPress fetch the miner JSON directly or expose the C# output as a stable HTTP JSON endpoint that WordPress reads. is right that this will be done in PHP; use the Widgets API or a shortcode to place the output where you want. Widgets – Theme Handbook. (developer.wordpress.org) Use the WordPress HTTP functions such as wp_remote_get to perform safe requests. (developer.wordpress.org)

Suggested flow (server-side):

  • Check a transient cache (get_transient). If empty, call the remote API with wp_remote_get, verify no WP_Error and response code 200, then get the body with wp_remote_retrieve_body. Decode JSON with PHP’s json_decode() and store the decoded array in a transient (set_transient) for a short period (e.g., 30–300 seconds). [set_transient / get_transient docs]. (developer.wordpress.org)
  • Always sanitize output with esc_html() or wp_kses() before printing.
  • If you need client-side live updates, build a small REST endpoint or use the WP REST API and fetch via AJAX from the front end. REST API Handbook. (developer.wordpress.org)

Minimal pattern (core idea):

$cache = get_transient('miner_api_cache');
if ( false === $cache ) {
  $resp = wp_remote_get('https://api.example.com/endpoint', ['timeout'=>10]);
  if ( ! is_wp_error($resp) && wp_remote_retrieve_response_code($resp) === 200 ) {
    $body = wp_remote_retrieve_body($resp);
    $data = json_decode($body, true);
    set_transient('miner_api_cache', $data, 120);
    $cache = $data;
  }
}
echo esc_html( $cache['hashrate'] ?? 'n/a' );

Notes and troubleshooting: set a sensible timeout and cache duration to avoid rate limits; include API keys in wp_remote_get headers if needed; check SSL verification (sslverify) for remote hosts; inspect is_wp_error() and response codes when debugging. See PHP’s json_decode() for safe decoding practices. (php.net)

WP is PHP. Work with that if you're trying to implement an external API within a native widget.
