APK to API
Turn an Android app into a working interface.
Capabilities
What SReverse reconstructs
Specific reverse engineering areas, each with its own page. The app usually needs more than one of them.
Open
Undocumented APIs
Find and reconstruct an API that is not public.
Android Automation
Use app functionality without driving the UI.
Protected APKs
Analyze obfuscated and packed builds.
Request Signing
Reproduce a dynamically generated signature.
Authentication
Rebuild the login, session and token flow.
Native / JNI
Follow logic that moved into native .so code.
DRM and Media
Reconstruct media and license request flows.
Also in a project
One app can use several request layers
An Android screen can call Kotlin code, a Flutter or React Native runtime, a native library and a remote service in one interaction. We follow the flow across those layers until each input to the backend request has a clear source.
What we can reconstruct
- REST, GraphQL, WebSocket and protobuf request flows.
- Login, token refresh, cookies and device registration.
- Dynamic headers, request signatures and encrypted payloads.
- Native JNI functions used by Java, Kotlin or cross-platform code.
- Entitlement, manifest and license-proxy calls used by media apps.
Outputs your team can use
Every delivery includes a Python client, JavaScript/TypeScript client, Postman collection and API documentation for the full application flow, its state, errors and working examples.

Start a project
Send the full APK
Send the full APK. We review the application and quote its complete API reconstruction.
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.
