Endpoints

15 endpoints. Infinite possibilities.

All backed by a single API key. Mix, match, and nest data categories.

Features

Built for developers who care about quality.

Realistic, varied, and predictable. Six things that make DummifAI different from a flat JSON file or a one-off Faker script.

PRO

🤖

AI Data Generation

Describe what you need in plain English — "10 fintech customers from Berlin" — and get realistic, coherent JSON. Powered by Gemini.

⚡

Zero Config

No databases to seed, no Docker containers to spin up. One API key, infinite data.

🎲

Realistic Variance

Data shifts daily using seeded algorithms so your UI testing stays authentic run after run.

🔒

Full OpenAPI 3.0 spec available. Import directly into Postman, Insomnia, or generate a client SDK.

Why DummifAI

The fastest way to populate a UI you haven't built yet.

DummifAI replaces the four hours you'd spend writing Faker fixtures or massaging a CSV. One API key, every shape of data your app needs.

One API key, everything

Sixteen endpoints — stocks, crypto, jobs, people, orders, invoices, logs — and a real AI endpoint, all behind the same key.

Webhooks & SSE built in

Live tick streams over Server-Sent Events. Outbound webhooks for whatever event you want. No socket plumbing required.

Custom schemas in seconds

Describe a shape, get a dedicated mock endpoint instantly. Versioned, per-key, with quotas you control.

Part of Response Bridge

One identity across Sentendra, DetectionLint, VisuTrack, CaseBridge and DummifAI. One bill, one invoice, one team.

Live streaming · SSE

Real-time data. No WebSockets.

The /stream endpoint pushes live ticks over Server-Sent Events. Your frontend just reads a stream — no polling, no sockets, no complexity.

const source = new EventSource(
  '/api/v1/stream?count=20',
  { headers: { Authorization: 'Bearer sk_...' } }
);

source.onmessage = (e) => {
  const tick = JSON.parse(e.data);
  updateChart(tick);
};
