Who it's for
If your app needs to read user bank transactions, OS3N Flow saves you weeks of provider integrations.
Show users every transaction across every bank — Revolut, Chase, Monzo — in one feed.
Pull business bank activity for bookkeeping, invoicing, and tax automation.
Our proxy layer lets your partner serve thousands of end users under one API key.
Aggregate client accounts across countries for advisors and family-office dashboards.
How it works
Sign up, open the dashboard, generate a key in seconds.
Use our drop-in Plaid or TrueLayer flow. Tokens are encrypted at rest.
GET /api/public/v1/transactions returns normalized data across providers.
Add bank data to any Lovable app
Drop a “Connect bank account” button into your Lovable project. One API key, three magic endpoints, and your users see their real transactions inside your app.
Built for production
Every provider token is encrypted before it touches the database.
Same fields whether the source is Plaid or TrueLayer.
US, Canada, UK, EU today. LATAM next via TrueLayer.
Cron-driven incremental pulls. Cursors where supported.
Simple pricing
Start free. Upgrade when you connect real users. Provider fees (Plaid / TrueLayer) are passed through transparently on paid plans.
