Build banking, not infrastructure

An ISO 20022-style REST API for accounts, transfers and webhooks. Clean, versioned endpoints let you build banking directly into your product.

• RESTful, versioned endpoints for accounts, payments and balances
• ISO 20022-style message structures for interoperability
• Scoped API keys with expiry and revocation
• Bearer-token authentication over HTTPS

Interactive documentation with scoped API keys and sandbox credentials, so your team can explore every endpoint before you go live.

• Reference docs for every endpoint, parameter and response
• Worked examples and copy-paste code snippets
• Error codes and rate-limit guidance
• Authentication and webhook-signature walkthroughs

A test environment with demo data to build and validate integrations safely — fully isolated from production and available 24/7.

• Instant sandbox credentials with demo customers and accounts
• Simulated transfers, cards and crypto orders
• Safe, reversible environment for integration testing
• Mirror of production behaviour with zero real funds

Real-time event delivery with HMAC-signed payloads, so your systems always know when money moves — securely and at scale.

• Event-driven notifications for payments, accounts and cards
• HMAC-SHA256 signed payloads for integrity verification
• Timestamped requests with replay protection
• Retry with backoff and per-endpoint delivery logs
