The White-Label API is the path where you own the screens. Your backend holds a workspace API key, your front end owns the experience, and the Onstacks intelligent routing engine does the rest.

​
Built on the intelligent routing engine

The power of Ramp is the routing engine behind it. You state an intent: the direction, the asset and amount, the market, and the rail. The engine finds every licensed provider that can settle that intent, quotes them all at once, ranks them by what the recipient receives after fees, executes with the one you confirm, and reconciles the result. You never integrate a provider, choose a network, or maintain a rate table.
  • One intent, many providers. Every quote response is a ranked set of real options from different providers, not a single price.
  • Manual or automatic. Show the options and let the user choose, or let the engine pick and create the payment in one call.
  • Coverage that grows on its own. New providers and corridors appear in the routes endpoint the moment they are enabled, with no change to your integration.

Objects

​
Lifecycle

Every endpoint takes environment and a workspace API key. Amounts are decimal strings in minor units for fiat and base units for stablecoins. Assets, networks, countries, and providers are referenced by code, never by internal ids.

Quotes

Discover coverage, request quotes, confirm one.

Payments

Create, read, and list payments; funding instructions.

Status tracking

Poll or receive webhooks.

Onramp

Fiat in, stablecoins out, through the same calls.
The endpoint reference is under API Reference → Ramp.
