Here are a few good options for a mock REST API for testing, depending on what you need:

Quick hosted mock APIs

Local mock server tools

  • Mockoon — very easy GUI for creating local mock REST APIs.
  • json-server — turns a JSON file into a REST API quickly. 
    npm install -g json-server
json-server --watch db.json --port 3000
  • WireMock — powerful for contract/integration testing.
  • Prism — mock API from OpenAPI specs.

Example of a simple mock API using json-server

db.json

{
  "users": [
    { "id": 1, "name": "Alice" },
    { "id": 2, "name": "Bob" }
  ]
}

Run:

json-server --watch db.json --port 3000

Then test:

  • GET /users
  • GET /users/1
  • POST /users

If you want, I can also give you:

  1. a local mock REST API setup
  2. a Docker-based mock API
  3. a mock API with auth/errors/pagination

How can brands improve their AEO?

Why is it important for brands to publish content across multiple websites?

Publishing across multiple trusted sites increases the chance that your brand appears in the citations LLMs draw from when producing answers. Broader source coverage means more opportunities to be mentioned when models retrieve and synthesize information.
