JSON Mock API

Features

Everything you need to mock APIs and test your apps.

JSON to API

Paste or upload JSON. Set an endpoint name. Your API is live at http://scripts.vaultifier.space/jsonmockup/api/your-endpoint.

HTTP methods

Support GET, POST, PUT, DELETE — or allow all. Control which method your endpoint accepts.

Response delay

Simulate slow networks. Set a delay in milliseconds (e.g. 2000 ms) to test loading states.

Status codes

Return 200, 201, 400, 401, 404, 500 — or any code you need to test error handling.

Custom headers

Set response headers (e.g. Content-Type, X-Custom-Header) per endpoint.

Faker placeholders

Use {{name}}, {{email}}, {{uuid}}, {{date}} in your JSON for random data on each request.

Example request

GET http://scripts.vaultifier.space/jsonmockup/api/users
Accept: application/json
