One API Instead of a Banking Relationship Per Corridor
Integrating cross-border payments the traditional way means negotiating a relationship per corridor: a bank in one country, a correspondent in another, a reconciliation process that's different for each pair. Each one is its own onboarding, its own SLA, its own failure mode. A payment API that actually abstracts this gives you one integration surface instead of N banking relationships.
That's the difference worth building for, and it's a structural one, not a convenience layer on top of the same plumbing.
What the API Actually Replaces
Underneath, Modality's API quotes and executes against 595 direct currency pairs across 35 currencies — the corridor logic, the spread calculation, the rail selection (SEPA, SEPA Instant, SWIFT, Faster Payments, local schemes, or a stablecoin leg on BTC, ETH, SOL, XRP) all sit behind the call. You're not integrating a settlement network yourself. You're calling an endpoint that already has.
Why This Matters for a Technical Reader
Same-day settlement instead of 2-5 business days changes what you can build on top — refund flows, payout scheduling, reconciliation — because you're not designing around multi-day uncertainty. Settlement running 24/7 means your system doesn't need special-case logic for weekends or bank holidays. And because Modality is non-custodial — licensed partners hold the funds, Modality provides the routing and settlement software only — you're integrating a rails layer, not taking on custody risk as a side effect of calling an API.

FAQ: Stablecoin Payment API
Is there a stablecoin settlement API for B2B payments?
Modality's settlement layer is API-first: one API connects a business to 595 direct currency pairs across 35 currencies and 63 countries, settling through licensed partners without integrating each corridor separately.
How do B2B stablecoin payments work end to end?
A business gets a quoted rate, converts and settles directly across one of 595 currency pairs, and the receiving side gets local currency -- non-custodially, since licensed partners hold the funds, not Modality.
What is a stablecoin payment platform for B2B businesses?
It's the technology layer between a business and licensed institutions -- quoting, converting and routing payments over stablecoin rails. Modality's version is non-custodial and settles 595 direct currency pairs.
