Overview
Randommer is a multi-purpose random data API that generates names, phone numbers, credit card numbers, text, and more — all through a single key-authenticated endpoint. It is a great one-stop shop for filling test forms with believable fake data. Register for a free API key to get started.
Beginner Tip
Pass your API key in the X-Api-Key request header rather than as a query parameter — this is the most common source of 401 errors for new users.
Available Data
The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.
Example Response
Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.
{
"status": "success",
"data": {
"result": "Data from Randommer",
"description": "Random data generator",
"timestamp": "2025-01-15T10:00:00Z"
}
} Field Reference
(array of strings) Most endpoints return a JSON array of generated strings, e.g. ["John Smith", "Jane Doe"] Implementation Example
Calls a real endpoint of this API. Replace any placeholder credentials with your own key.
const url = "https://randommer.io/api/Name?nameType=fullname&quantity=5";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
headers: {
"X-API-Key": "YOUR_API_KEY"
}
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data); What Can You Build?
