Building GhanaAPI: A Comprehensive REST API for Ghanaian Services
As a developer passionate about solving real-world problems, I identified a significant gap in the Ghanaian tech ecosystem: the lack of unified, reliable APIs for essential local services. This led me to create GhanaAPI - a comprehensive REST API that provides developers with streamlined access to crucial Ghanaian data and services.
🎯 The Problem
Before GhanaAPI, developers building applications for the Ghanaian market faced several challenges:
- Fragmented Services: Different providers for addresses, exchange rates, and location data
- Inconsistent APIs: Varying data formats and response structures
- Limited Documentation: Poor or non-existent API documentation
- Reliability Issues: Frequent downtime and inconsistent service quality
🚀 The Solution: GhanaAPI
GhanaAPI addresses these challenges by providing a single, unified platform with:
🏠 Digital Address Services
- Ghana Post Digital Address validation and lookup
- Precise geocoding and reverse geocoding
- Address search and standardization
- Sub-200ms response times
💱 Real-time Exchange Rates
- Live GHS exchange rates from Bank of Ghana
- Historical data and trend analysis
- Multi-currency support (USD, EUR, GBP, NGN)
- Automatic rate updates every hour
🌍 Location & Administrative Data
- Complete regional and district information
- All 16 Ghana regions with detailed metadata
- Administrative boundaries and geographic data
🚗 Transport & Logistics
- Route calculation and turn-by-turn directions
- Transport stops and station information
- Real-time fuel prices from National Petroleum Authority
- Travel cost estimation
🛠 Technical Architecture
The API is built with modern technologies to ensure scalability and reliability:
- Backend: Node.js with TypeScript for type safety
- Framework: Express.js with comprehensive middleware
- Documentation: OpenAPI 3.0 with interactive Swagger UI
- Caching: Intelligent caching for optimal performance
- Validation: Comprehensive input validation and error handling
Key Features:
// Example: Get current exchange rates
const rates = await fetch(
'https://api.ghana-api.dev/v1/exchange-rates/current?currencies=USD,EUR'
);
// Example: Validate digital address
const validation = await fetch(
'https://api.ghana-api.dev/v1/addresses/validate/GA-123-4567'
);
// Example: Calculate route
const route = await fetch(
'https://api.ghana-api.dev/v1/transport/route-calculation?start_lat=5.6037&start_lng=-0.187&end_lat=6.6885&end_lng=-1.6244'
);
