Overview

Introduction

Due provides modern (borderless) payment infrastructure for global businesses. Our APIs make it simple to move money across borders, connect traditional finance with blockchain networks, and accept payments in both fiat and digital assets — all through a unified interface.

With Due, businesses can expand into new markets, access global payment networks, and benefit from faster, more cost-effective transfers and settlements.

Transfers API

The Transfers API enables seamless cross-border payments and asset transfers. It connects blockchain networks to local payment systems in over 80 countries and supports SWIFT USD/EUR/GBP payments in more than 150 countries.

You can easily convert between fiat and digital assets — including stablecoins like USDC, EURC, and USDT — and move funds across networks.

The API also supports Virtual Accounts, allowing you to receive local fiat payments (e.g., via ACH, SEPA, Faster Payments) that settle directly into digital assets like USDC.


Supported payment methods include:

  • Bank transfers (ACH, SEPA, FPS, SPEI, and more)
  • Crypto rails (USDC, USDT, ETH, etc. across multiple networks)
  • Mobile money (e.g., M-Pesa)
  • QR code payments (e.g. PIX)
  • Coming soon: Cards, Wallets (e.g. AliPay)

Example use cases:

  • Receive NGN via bank transfer → Settle in USDC on Base (Fiat Pay-In → Stablecoin)
  • Send USDC on Polygon → USD in a bank account via ACH (Stablecoin → Fiat Payout)
  • Transfer USDC from Arbitrum → USDC on Starknet (Cross-Chain Transfer)
  • Send MXN via SPEI → Receive GBP via Faster Payments (Cross-border FX)
  • Issue virtual IBANs to collect EUR → Auto-settle into USDC wallet (Virtual Accounts)
  • Swap EURC → USDC in your wallet (Digital Assset Exchange)

FX API

The FX API gives you public access to Due’s live pricing engine — letting you discover available currency pairs, check real-time exchange rates and spreads, estimate conversions, and retrieve historical price data. It's ideal for surfacing transparent pricing to your users, building internal tools, or powering analytics.

  • No authentication required for read-only access
