Selecting between a free exchange rate API and a paid one can determine how smoothly your product scales. Startups and developers need a clear, practical framework to evaluate trade-offs in cost, accuracy, and scalability.

Understanding Exchange Rate APIs

What They Do

  • Retrieve real-time or historical currency conversion rates.
  • Integrate with fintech platforms, e-commerce pricing, or reporting tools.

Pricing Models Overview
