curl -s "https://apixies.io/api/v1/convert-timestamp?timestamp=1700000000" \
  -H "X-API-Key: YOUR_API_KEY"

const res = await fetch("https://apixies.io/api/v1/convert-timestamp?timestamp=1700000000", {
  headers: { "X-API-Key": "YOUR_API_KEY" }
});
const data = await res.json();
console.log(data);

$ch = curl_init("https://apixies.io/api/v1/convert-timestamp?timestamp=1700000000");
curl_setopt_array($ch, [
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HTTPHEADER => ["X-API-Key: YOUR_API_KEY"],
]);
$data = json_decode(curl_exec($ch), true);
curl_close($ch);

print_r($data);

import requests

res = requests.get(
    "https://apixies.io/api/v1/convert-timestamp",

Response

The result sits under data in the standard envelope. See the response format guide for errors and status codes.

returns

data.iso8601: The time in ISO 8601, in the timezone you picked.
data.unix: Unix timestamp in seconds, with milliseconds in unix_ms.
data.human: Readable form, like November 14, 2023 10:13:20 PM.
data.relative: Distance from now, like 2 years ago.
data.rfc2822: RFC 2822 form, the one email headers use.
data.day_of_week: Weekday name, with date and time in their own fields.
