The platform
Cards, UPI, wallets, and payouts — engineered as a single rail so your finance team doesn't reconcile across five vendors at 2 AM.
Adaptive ML routing across 14 acquirers lifts approval rates by up to 4 points — recovered revenue, no engineering work.
Send funds to bank accounts in 38 countries — under 30 seconds, weekends included. Goodbye T+2.
Real-time risk scoring on every transaction. Block bad actors, approve good customers — without lifting a finger.
A single REST + webhook surface. SDKs for 8 languages. Idempotent everything. Sandbox in 60 seconds.
POST /v1/charges { "amount": 4200, "currency": "usd", "source": "tok_..." }
Accept 135 currencies and 28 local payment methods. Auto-localized checkout that converts.
Every fee, every cent, exportable to your warehouse. Reconciliation that finance actually trusts.
How it works
A streamlined path from KYB to live payments — no procurement cycle, no surprise fees.
Verify your business with our streamlined KYB. Plug in tax info, owners, and bank — that's it.
Drop in our hosted checkout, install the SDK, or build directly against the API. Test mode included.
Switch to live keys and start collecting. Add new currencies, methods, and payouts as you grow.
// Accept your first payment in 6 lines import ProtonPay from '@protonpay/sdk'; const pay = new ProtonPay(process.env.PP_KEY); const session = await pay.checkout.create({ amount: 4900, currency: 'usd', success_url: 'https://acme.com/success', }); return redirect(session.url);
No mandatory phone screens. No 90-day procurement cycles. No "talk to sales" walls between you and your first dollar of revenue.
We cut our payment costs by 31% in the first quarter and our approval rate jumped 4 points. ProtonPay paid for itself before our first invoice cleared.
Their docs are the cleanest I've seen since Stripe circa 2014. Migrated in a single sprint, zero downtime, and the dashboard is genuinely beautiful.
Instant payouts changed how we run marketplace operations. Sellers see funds in seconds — our retention numbers tell the rest of the story.
Activate your account in minutes, no card required. Move to live as soon as you're ready.
