How It Works
Define Your Schema
Create your API schema in JSON format. Specify the structure, data types, and any constraints for your mock API.
{
"users": [
{
"id": "string:uuid",
"name": "string:name",
"email": "string:email",
"role": "string:enum:admin,editor,viewer",
"created_at": "date:past"
}
]
}{
"users": [
{
"id": "f7c5c8d1-9f3a-4b5c-8e7d-6f5a4b3c2d1e",
"name": "Alex Thompson",
"email": "alex@example.com",
"role": "admin",
"created_at": "2023-10-15T14:32:10Z"
}
// More users would appear here
]
}{
"product": {
"id": "number:id",
"name": "string:product",
"price": "number:price",
"inStock": "boolean",
"tags": "array:string:3"
}
}Generate Your API
Our AI analyzes your schema and generates realistic mock data. You'll get a unique endpoint and a preview of the response.
Use Your API
Integrate the API endpoint into your frontend application. The data will be consistent across requests, allowing for reliable testing and development.
// In your frontend application
fetch('https://spineless-api.app/mock/users-abc123')
.then(response => response.json())
.then(data => {
console.log(data.users);
// Use the mock data in your app
});
