ReqRes

Overview

ReqRes provides mock user data (list, detail, create, update) — historically keyless.

⚠️ Status (verified 2026-08): the API now returns HTTP 401 {"error":"missing_api_key",...} with a hint to create a free key at app.reqres.in and send it as x-api-key — the service now requires a free API key. Get the key first.

Quick Start

Get a free key at app.reqres.in, then:

curl "https://reqres.in/api/users/2" -H "x-api-key: YOUR_KEY"

{
  "data": { "id": 2, "email": "janet.weaver@reqres.in", "first_name": "Janet", "last_name": "Weaver", "avatar": "https://reqres.in/img/faces/2-image.jpg" }
}

Authentication

• Register at app.reqres.in → free API key.
• Send it as the x-api-key header (missing → 401, verified).

Rate Limits & Notes

• Free tier with limits (check the docs); the mock data is unchanged.
• Endpoints: /api/users, /api/users/{id}, /api/users (POST), /api/login.

FAQ

Is ReqRes still keyless? No — it now requires a free key (x-api-key header, verified 401 without).

How do I get a key? app.reqres.in → create a free key.

What changed? The mock data is the same; auth was added.
