Authorized API integration & protocol analysis for banking, wallet and payment apps
You give us a target app name and your requirements; we deliver runnable API or protocol source code, plus the interface documentation to operate it. Our team has years of hands-on experience across mobile apps and fintech, covering protocol analysis, interface reconstruction, open-data integration, third-party API connectivity and automated data tooling.
What we deliver
From protocol analysis to runnable API source code — scoped to the finance apps you need to connect.
Open Data & Open Finance API Integration
Standards-aligned API layers that expose account, payment and identity data from banking and wallet apps to your own systems.
App Protocol & Traffic Analysis
Reverse-engineer an app's request/response protocols to produce a clean, documented integration surface.
Balance & Transaction-History Extraction
Programmatic access to account balances, ledgers and line-item transaction history.
Payment & Transfer Data Extraction
Read pending and completed transfers, payment batches and remittance records.
ERP & Accounting Sync
Push extracted data into QuickBooks, NetSuite, Xero or custom treasury dashboards — no manual CSV exports.
Runnable Source Code & API Docs
You receive working API / protocol source code and the interface documentation to run and maintain it.
Delivery process
From quote to packaged API test to source-code handoff — clear commercial steps.
Scope & quote
Share the target app and required data or actions. We assess difficulty and send a fixed quote from USD 500, with a 1–2 week build estimate.
Protocol analysis & build
We analyze the app’s interfaces under the agreed scope and implement a clean, documented integration layer.
Test via packaged API
When development finishes, you receive a packaged API for end-to-end testing — before any source-code handoff.
Pay & receive source code
After you accept the test results and payment clears, we deliver the full runnable source code plus interface documentation.
Pricing & delivery
Simple commercial terms per target app — scope first, then build, test, and hand over source code.
From USD 500 per app
Final quote depends on app difficulty, security controls, and the data or actions you need.
Typical build: 1–2 weeks
Clock starts after scope is confirmed. Complex apps or multi-flow scopes may take longer — we say so upfront.
Per-app engagement
Each banking, wallet, lending or investing app is scoped and priced on its own. Multi-app programs are quoted as a package.
From USD 500
Entry price for a single app. Harder reverse-engineering, stronger anti-bot, or wider API surface increases the quote.
1–2 week build
Most single-app integrations complete in one to two weeks after requirements are locked.
Test API before source handoff
When development finishes we first give you a packaged API for testing. After you accept the results and payment clears, we deliver the full source code and docs.

How much does one app cost?
Engagements start from USD 500 per app. The final quote depends on reverse-engineering difficulty, security controls, and how many data fields or actions you need.
How long does delivery take?
A typical single-app build takes 1–2 weeks after scope is confirmed. We flag longer estimates before work starts if the app is especially complex.
When do I get the source code?
After development we first provide a packaged API for testing. Once you are satisfied with the tests and payment is completed, we hand over the full source code and interface documentation.
What do you deliver?
A working integration for the named banking, wallet, lending or investing app: packaged API for UAT, then runnable source code plus docs after acceptance and payment.
Which markets do you cover?
India, Bangladesh, Pakistan, Thailand and Vietnam — UPI/MFS wallets, mobile banking, digital lending and investing apps popular in each market.
Is this authorized work?
Projects are scoped for authorized, licensed use cases under a clear statement of work — not unsolicited scraping of third-party systems.
