IDB Unveils APIBox: A New Open-Source Tool for Testing Open Finance Applications

MIAMI - The Inter-American Development Bank (IDB) has launched APIBox: Technology Sandbox for Open Finance, a solution using open-source technologies designed to help governments, financial institutions, and organizations test and validate open finance processes and standards.

Developed with the support of the Grand Duchy of Luxembourg, the solution was unveiled during the FinnLAC 2025 Forum, an event organized by the IDB Group to discuss the future of the financial industry in Latin America and the Caribbean.

APIBox acts as a technological sandbox, enabling participants to test new business models based in standardized Application Programming Interfaces (APIs). These APIs are at the core of open finance because they allow consumers to securely and efficiently share their financial data with third-party providers across a broad spectrum of services, including bank accounts, payments, investments, and insurance.

With APIBox, financial authorities and other stakeholders can build their own technology sandbox to dynamize the open finance ecosystem, and promote new solutions in a controlled environment, accelerating innovation and promoting greater financial inclusion.

"We aim to simplify the adoption of open finance by lowering the learning curve and encouraging the use of shared standards that safeguard security, enable interoperability, and protect personal data," said Anderson Caputo Silva, chief of the IDB's Connectivity, Markets and Finance Division. "Our goal is to build a more inclusive and transparent financial system across Latin America and the Caribbean."

Regulators and developers work together in APIBox to test, validate, and promote APIs development for open finance. This robust sandbox environment provides users with a comprehensive library of API documentation, tools that facilitate the compliance with technical standards, integration and data transfer tests using synthetic information, as well as tools to visualize results and validation reports.

Chile's Financial Market Commission has been the first financial authority to implement the technology sandbox with support from the IDB.

APIBox was developed by MInsait, an Indra Group Company, for the IDB, as part of the Bank's regional initiative to build digital public infrastructures for open finance and payments across the region.
