Multiple reference codes
Run up to 50 codes from one integration. Each code has its own markup — perfect for splitting traffic between a desktop app, a widget, and an embedded checkout, with separate billing per channel.
Beta
Private crypto exchange API.
Quote, create, get paid. Three signed calls, three webhook events, one production exchange behind them. Invite-only.
Hit the same button twice. Get the same order.
Every create call honours an Idempotency-Key, so a network blip never opens two orders. Same key + same body returns the original order. Same key + different body returns 409.
Webhooks deliver one event per status change — even when the order races NEW to DONE in three seconds. The status is frozen at queue time, so a slow delivery never carries a stale value.
Quote an exchange
with one HTTP call.
POST /api/v1/price returns a quote in three languages. Sign the exact bytes you send. Quotes are recomputed per request against live rates; a 30–60 s polling cadence is comfortable. markupBps is echoed back so you can reconcile billing. Unauthenticated callers see the base rate; signed callers see their own.

on day one.
Pay-as-you-trade.
No idle subscription.
You collect the markup you set on every order. No flat platform fee. High-volume partners can negotiate a share of the base service fee at onboarding.
Default
Your markup on top of ours.
Default for every partner. Set your markup (0–20 %, in basis points) on every quote and create; we re-quote and sign the rate. You keep the markup, we keep the base fee. No volume commitment, no contract.
Revenue share
Select partners split the base fee.
A configurable share of the base service fee, set on your partner record at onboarding. Terms live in your contract, not in your request payload. Stack it with your own markup.
