cURL to Python, JavaScript, and PHP
Python (requests)
import requests
response = requests.post("https://api.example.com/items", headers={"Content-Type":"application/json"}, data="{\"name\":\"sample\"}")
print(response.status_code, response.text)JavaScript (fetch)
const response = await fetch("https://api.example.com/items", { method: "POST", headers: {"Content-Type":"application/json"}, body: "{\"name\":\"sample\"}" });
console.log(response.status, await response.text());PHP (cURL)
$ch = curl_init("https://api.example.com/items");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_HTTPHEADER, ["Content-Type: application/json"]);
curl_setopt($ch, CURLOPT_POSTFIELDS, "{\"name\":\"sample\"}");
$response = curl_exec($ch);
curl_close($ch);JWT signer (HS256, HS384, HS512, RS256)
Signing does not validate token claims, issuer, audience, or authorization policy. Avoid production secrets in shared devices.

CSS specificity calculator
Specificity (IDs, classes/attributes/pseudo-classes, elements): 1, 2, 3
This quick estimate follows common selector forms; :is(), :not(), and :has() argument specificity can vary from this simplified count.
