Currencycloud

Currencycloud is a cross-border payments and foreign-exchange platform, part of Visa, that provides a robust, predictable REST API for converting money between currencies, holding multi-currency balances, and making payments around the world. Its API v2 spans 18 domains — authentication, accounts and sub-accounts, balances, beneficiaries, contacts, conversions, funding, payers, payments, quotes, rates, reference data, reporting, transactions, transfers and withdrawal accounts — and lets businesses dynamically register sub-accounts to offer white-labelled money-transfer services to their own customers. Currencycloud is an FCA-authorised Electronic Money Institution (registration #900199) and a FinCEN-registered money transmitter, and publishes official SDKs for JavaScript, Python, Ruby, PHP, Java and .NET.

Currencycloud publishes 2 APIs on the APIs.io network: API v2 and Onboarding API (beta pilot). Tagged areas include Company, Fintech, Payments, Foreign Exchange, and Cross-Border Payments.

The Currencycloud catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Currencycloud’s developer surface includes documentation, API reference, getting-started guide, authentication, signup flow, support, changelog, and 27 more developer resources.
