App without an API

No public API? Rebuild every API in the app.

Q: How long does it take?

The 24–72 hour delivery window starts after we receive the APK and any account access needed to run it. The fixed quote states the deadline. Most projects finish sooner.

Q: Will the finished API need Android?

We check software-generated values, hardware-backed keys and server-required integrity proofs during review. The quote states the deployment requirements.

Some software never ships a public API. The Android APK still contains the endpoints, protocols and backend workflows needed to rebuild the full API.

The problem

Your team wants to integrate with a product, and there is no public API to call. The only way to get the data is through the app, which means UI automation or nothing.

The route

We recover every endpoint and backend workflow from the APK. Your systems call them directly without running the Android app.

How it works

The app already has an interface to its backend

A product can lack a public developer API and still depend on structured requests for search, account data, bookings, uploads or status checks. We reconstruct the full application flow.

What the work covers

We identify every backend route, request shape and session rule. We reproduce changing values such as tokens, signatures, timestamps and device headers. The complete package includes Python, JavaScript/TypeScript, Postman and API documentation.

Every delivery contains the complete interface used by the app.

Why teams replace UI automation

No emulator fleet for a server-side task.
No selectors that break after a visual redesign.
Faster calls and clearer errors.
Direct use inside jobs, scripts and products.

The first message only needs the app name or APK.

Start a project

One full APK. One complete delivery.

Projects start at $120. Most are delivered in 24 to 72 hours.

Every format included

Python, JavaScript/TypeScript, Postman and complete API documentation cover the same full endpoint set. Your team runs the clients in its own server or system.

Ready in 24–72 hours

The delivery window starts after we receive the APK and any account access needed to run it. The fixed quote states the deadline. Most projects finish sooner.

Deployment checked before the quote

The package includes signing, encryption, decryption and session handling. We verify device-bound keys and server integrity checks during review and document runtime requirements before you commit.

30 days of fixes

Report a defect within 30 days of delivery. We fix any delivered call that does not match the tested APK at no extra cost.

Before you send the APK

What your team needs to know

Send the full APK through WhatsApp or email. We reply within one hour.

What does the delivery include?

Every endpoint, protection mechanism and backend workflow in the APK, delivered as Python, JavaScript/TypeScript, Postman and complete API documentation.

How long does it take?

The 24–72 hour clock starts when we receive the APK and any account access the app requires. Most projects finish sooner. Your fixed quote confirms the deadline.

Where does the finished API run?

It runs on your server or inside your system. We include setup instructions and review the deployment with your team.

Will the finished API need Android?

We check this during review. Software-generated values run in the clients. Hardware-backed keys and server-required integrity proofs have device dependencies; the quote states the deployment requirements.

What happens if a delivered call fails?

Report it within 30 days of delivery. We fix any delivered call that does not match the tested APK at no extra cost.
