Request

Send your key in the X-API-Key header. More languages and patterns live on the code examples page.

curl -s "https://apixies.io/api/v1/uuid?count=1" \
  -H "X-API-Key: YOUR_API_KEY"

const res = await fetch("https://apixies.io/api/v1/uuid?count=1", {
  headers: { "X-API-Key": "YOUR_API_KEY" }
});
const data = await res.json();
console.log(data);

$ch = curl_init("https://apixies.io/api/v1/uuid?count=1");
curl_setopt_array($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/uuid",
    params={"count": "1"},
    headers={"X-API-Key": "YOUR_API_KEY"},

print(res.json())

Authentication and limits

This endpoint needs an API key. Use the sandbox ("try it" above) to test it without registering. See the authentication guide for details.

Standard rate limits apply to this endpoint.

Common use cases

Database primary keys

Generate UUID v4 or v7 identifiers for use as database primary keys in distributed systems where auto-increment IDs aren't suitable.

Session and token generation

Create unique session identifiers, correlation IDs, or idempotency keys for API requests and distributed tracing.

File naming and deduplication

Generate unique filenames for uploaded files to prevent collisions in storage systems. Use UUIDs as folder names for user-specific content.
