What can you build with API v1.0.0?

API v1.0.0 is a Finance API. Developers commonly use finance APIs for:

processing payments and handling transactions
building subscription and billing systems
automating invoicing and financial reporting
fraud detection and risk scoring
connecting to banking and accounting software

No authentication required. This API is open — no signup or key needed. Ideal for quick prototypes and public-facing features. API v1.0.0 is free to use, making it a low-risk choice to experiment with.
