The Currency API That Powers Our Clients' Global Pricing
Introduction
In a world where financial systems operate across borders, real-time exchange rates are essential. That’s why every Teruza-powered platform comes with built-in access to our Currency API, offering up-to-date rates for both fiat and cryptocurrency pairs.
From quoting and invoicing to trading, reporting, and alerting — this live data feeds critical business logic across our ecosystem. Whether you're calculating BTC/ZAR values for a trade, or pricing a product in GBP for a ZAR-based customer, the Currency API keeps things accurate, fast, and seamless.
--- Ardi Coetzee, Chief Technology Officer at Teruza"Our clients operate across borders. We make sure their systems speak every currency — instantly, accurately, and without extra cost."
The Problem
Many platforms struggle with accessing reliable, real-time exchange rate data — especially when dealing with both traditional and digital assets. Free APIs are often inaccurate or rate-limited, while premium services are expensive, slow, or difficult to integrate.
Inaccurate rates can lead to:
- Misleading quotes
- Incorrect margins
- Poor customer experience
- Missed opportunities in volatile markets
Additionally, relying solely on bank APIs for pricing during user interactions isn’t ideal — they're designed for final trade execution, not for real-time user-facing data. What’s needed is a hybrid approach: fast, indicative rates for the front-end, and verified, final rates during actual booking.
Our Solution
We built the Teruza Currency API to bridge the gap between live indicative pricing and final settlement data. It fetches and intelligently caches exchange rates from multiple trusted sources, covering both fiat currencies and major cryptocurrencies — and it’s free for all Teruza license holders.
Features include:
- Live indicative pricing for use in quotes, invoices, and dashboards
- Coverage of major pairings: USD/ZAR, GBP/ZAR, BTC/ZAR, ETH/ZAR, and more
- Support for both traditional markets and crypto exchanges
- Secure, developer-friendly API access
- Optional integration with bank APIs (e.g. Investec, Capitec, Access Bank etc) for final settlement pricing
For non-Teruza users, the API is available under standard usage-based pricing, but license holders enjoy unlimited access at no additional cost.
Impact
- Clients get accurate, real-time indicative prices without relying on slow or expensive third-party APIs
- Live exchange rates now power everything from multi-currency quoting to crypto trade automation
- Faster user decisions, driven by up-to-date and transparent currency info
- Tighter profit margins through real-time pricing and automated recalculation
- Seamless integration into dashboards, apps, pricing engines, and alerts
