Best for
Frontend QA
The fastest way to test list pages, next and previous buttons, filters, and infinite-scroll UI.
Endpoint
Best for
React tables, admin dashboards, list views, demo data, and pagination tests.
Returns
`users`, `pagination`, `links`, and filter-aware metadata.
Quick start endpoints
These are the three most useful endpoints when you want live data in a project right away.
Option 1
Basic user collection with metadata and pagination shape.
Option 2
Best endpoint for testing page navigation and list UIs.
Option 3
Great for cards, catalogs, prices, filters, and search UIs.
This is the kind of data shape you can use immediately in a user table or admin dashboard.
The responses are shaped for actual interface work instead of fake placeholder blobs.
Admin tables
Test pagination, row actions, filters, badges, and detail drawers with realistic records.
Storefront UI
Render product cards, categories, pricing blocks, and order history without a backend.
Learning fetch
Practice loading, success, empty-state, and mapping logic with predictable JSON responses.
Client demos
Ship clickable prototypes faster by wiring real endpoints into your UI before the API is ready.
Profiles, detail pages, statistics, and pagination.
All Users
Collection response with pagination metadata.
Paginated Users
Supports page, limit, role, and status query params.
Single User
Detail response for profile pages and route testing.
User Stats
Analytics-style data for dashboards and widgets.
Products, categories, orders, and sales analytics.
Products
Catalog records with price, inventory, and attributes.
Product Categories
Useful for category filters and menu builders.
Orders
Order history for account pages and admin tables.
Order Analytics
Dashboard metrics for charts and reporting cards.
Health checks, config payloads, and status responses.
Health
Simple uptime and API health response.
Configuration
Configuration-style JSON for app settings screens.
Status
System state payload for monitoring UI testing.
Supported query params
- page: page number starting at 1
- limit: records per page
- role: optional role filter
- status: optional status filter
Example requests
https://formatjsononline.com/api/users/paginated?page=1&limit=2
https://formatjsononline.com/api/users/paginated?page=2&limit=2
https://formatjsononline.com/api/users/paginated?page=1&limit=3&status=active
JavaScript fetch
fetch('https://formatjsononline.com/api/users/paginated?page=1&limit=2')
.then((response) => response.json())
.then((data) => console.log(data));What to test with it
Page counters, disabled previous and next buttons, empty states, filters, skeleton loaders, and table footers with total counts.
Example paginated response

"success": true,
"data": {
"users": [
{
"id": "usr_1",

},
{
"id": "usr_2",
"email": "jane.smith@example.com",
"firstName": "Jane",
"lastName": "Smith",
"role": "user",
"status": "active"
}
],
"pagination": {
"currentPage": 1,
"totalPages": 3,
"totalItems": 6,
"itemsPerPage": 2,
"hasNextPage": true,
"hasPreviousPage": false
}
},
"links": {
"self": "/api/users/paginated?page=1&limit=2",
"next": "/api/users/paginated?page=2&limit=2",
"prev": null
}

Use the AI JSON Generator to create project-specific data and publish your own live endpoint when these sample APIs are close but not quite right.
Built for real frontend testing
Everything here is designed to remove friction. You can prototype, teach, QA, or demo without pausing to build a backend first.
Test cards, tables, forms, detail pages, and loading states with predictable JSON.
Practice fetch, axios, async flows, and response handling without backend setup.
Build demos that look real without spending time on backend infrastructure first.
Validate filtering, pagination, empty states, and error-safe UI behavior.
Frequently Asked Questions
Common questions about Dummy Api conversion and usage
Are these real working API endpoints?
Yes. These are live GET endpoints that return structured JSON immediately, so you can test frontend apps, API clients, demos, and tutorials without building your own backend first.
Do these APIs require authentication?
No. They are intentionally open for development, learning, and prototyping. You can test them directly in the browser, Postman, curl, or frontend code without API keys or login.
Do you support pagination for testing list endpoints?
Yes. Use the paginated users endpoint with query parameters like page, limit, role, and status to test table navigation, list pagination, filter states, and infinite-scroll patterns.
Can I use these APIs in tutorials and courses?
Yes. They are great for educational content because students can start making requests immediately, get predictable responses, and avoid backend setup complexity.
Can I create my own custom API endpoint?
Yes. Use the AI JSON Generator to create your own JSON structure and publish it as a live mock API endpoint when you need a custom schema or a project-specific dataset.
