ScalableAPI
For fintech compliance & ops
API transaction trails reviewed before partners and regulators ask.
We audit how payment and ledger API calls move money and records — then hand your team a findings pack you can act on.
Flagship work
Independent reading of the paths that move money
Our core engagement is the API Transaction Audit Review: sampled trails, control gaps, and a remediation sequence sized for the people who own each fix.
Fintech teams come to us when a bank questionnaire lands, a release touches settlement, or month-end reconciliations keep producing the same unexplained differences. We do not sell a monitoring subscription. We deliver a time-boxed audit with a named scope and a written pack.
Working from Yuanlin, we schedule around Taiwan business hours and partner calendars across the region.

Other ways teams bring us in
Pre-Release Transaction Control Check
A focused pass before a payment or ledger release — checking that new API routes still honor approval rules, idempotency, and settlement handoffs.
Partner Trail Diligence Support
Help for fintech teams answering partner or bank diligence questions about how API-originated transactions are monitored and reconciled.
Exception Handling Workshop
A facilitated working session for operations and engineering to agree how failed, duplicated, or delayed API transactions should be detected and closed.
“They caught a retry path that posted twice to settlement after our gateway had already marked the call complete. The report named the owner — that mattered more than the severity label.”— Mei-Ling Chen, Compliance Lead, regional payments firm
