What is DecoderFX?

DecoderFX is a live currency conversion REST API built for developers worldwide that need accurate, real-time exchange rates. Most currency APIs either ignore African currencies or charge premium prices for them. DecoderFX changes that.

With support for 166 currencies including NGN, GHS, KES, ZAR, ETB and all major global currencies, DecoderFX gives you accurate rates updated every hour — sourced from central banks and live forex feeds.

Why African Developers Need DecoderFX

If you have ever built a fintech app, e-commerce platform, or payment system and needed reliable currency conversion, you know the pain. Most popular APIs either:

• Do not support NGN, GHS, or KES properly
• Charge expensive monthly fees just to access African currencies
• Have outdated rates that do not reflect real market conditions

DecoderFX was built to solve exactly this problem.

Key Features

• 166 currencies supported — including all major African currencies
• Rates updated every hour — always accurate, never stale
• Simple REST API — integrate in under 5 minutes
• Free tier available — 100 requests per day, no credit card required
• Affordable paid plans — from $5/month for 1,000 requests/day
• Convert any pair — not just USD base, convert NGN to GHS directly
