APK API extraction service

APK API extraction service for complete Android workflows

Send the APK. We recover every callable backend workflow and deliver code your system can run without the Android interface.

Choose the result, not the label

APK decompilation, endpoint extraction and API reconstruction produce different results. SReverse delivers a working API package for the full application.

ServiceWhat you receiveWhat remains
APK decompilationRecovered resources, manifest data and readable parts of Java, Kotlin or Smali code.You still trace requests, rebuild state and write the client.
Endpoint listHosts, paths and request names found in code or traffic.You still reproduce authentication, signatures, encryption and request order.
Security reportFindings about the app, its protections and exposed risks.You receive analysis, not a callable replacement for the app workflow.
Hourly reverse engineeringAnalysis and code produced during the booked time.The final output depends on the scope, hours and delivery terms you set.
SReverse full API reconstructionPython, JavaScript, TypeScript, Postman and complete API documentation for every callable backend workflow in the APK.Device-bound keys or server integrity checks are documented when the backend requires a live Android device.

What the API package includes

We recover endpoints, request bodies, response models, authentication, token refresh, cookies, signatures, timestamps, nonces, device values, encryption, decryption and request order. The same endpoint set is delivered in every format.

Static and runtime analysis work together

JADX or Ghidra can reveal code and native libraries. Burp Suite, Frida and runtime tracing show the values created while the app runs. We follow the full path from the screen action to the bytes sent to the backend, then rebuild that path as callable code.

Test the delivery format

The public APK to API example runs login, token refresh, AES-GCM encryption, HMAC signing and failure handling in Python, TypeScript and Postman. Your project uses the same delivery structure with the real app workflow.

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.
