Builder & Partner Platform
Build with Xace. Ship Finance, Fast.
Embed accounts, payments, FX, and approvals straight into your product—on infrastructure trusted by iGaming leaders and built for regulated scale.
What you unlock
Banking infrastructure, ready to compose
Accounts, payments, FX, webhooks, and controls — available as clean API primitives that slot into your product without rebuilding the regulated layer underneath.
Composable banking primitives
Clean, versioned REST APIs covering accounts, payments, FX, webhooks, Open Banking, and approval controls. One integration surface for the entire financial layer — no reinventing regulated infrastructure.
Full sandbox from day one
Test every banking scenario before going live. Full-featured test environment with realistic ledger states, Postman collections, and documentation so your integration is proven before it counts.
Partner and brand enablement
Launch under your brand or extend your platform with Xace as the infrastructure. Commercial support, technical onboarding, and a dedicated partner team behind every build from proof-of-concept to go-live.
Three ways to build
Bring banking into your product experience
Account data, payments, and FX actions surfaced directly inside your product flow — so users never leave your environment to handle their money.
REST API access across every banking primitive
Clean, versioned endpoints for accounts, payments, FX, and approvals. One integration point for the entire banking layer — with no undocumented gotchas.
Test every scenario before going live
Full sandbox with realistic ledger states and test data. Validate your integration logic without touching production balances or rails.
Standards-based connectivity from the start
OAuth 2.0 with granular permission scopes means Xace fits your existing stack rather than requiring an architecture rework to accommodate banking.
The API surface
Every banking primitive, documented and ready to integrate
Accounts, payments, FX, webhooks, Open Banking, and approval controls — each with clean REST endpoints, versioned contracts, and full reference documentation. The API surface is the product, not a side door. Teams integrate once and get access to every primitive as the platform grows.
Developer experience
From sandbox to production in days, not months
Full-featured sandbox, Postman collections, quickstart guides, and a developer portal that covers every integration scenario. Technical teams spend their time building, not troubleshooting the banking layer. Dedicated technical support is available from the first architecture review through to go-live.
Branded and partner builds
Your brand. Your experience. Xace underneath.
Launch a fully branded financial product on top of Xace's regulated rails. Custom UI, your domain, your customer relationship — with the infrastructure, compliance framework, and operational support handled by Xace. Platform partners and technology integrators get commercial and technical enablement throughout the build.
Proven by builders
The infrastructure behind financial products that actually ship
Building financial products is hard. The regulated infrastructure layer alone — accounts, payment rails, FX, KYC, controls — takes years to build correctly and remains the highest-risk part of every financial product roadmap. Xace removes that constraint.
Builders and platform teams across payments, treasury, affiliate, and embedded finance use Xace to compress their go-to-market timeline from months to weeks. The API surface is complete, the documentation is accurate, and the partner team is technically engaged from the first integration conversation to go-live and beyond.
