## Public API Endpoints

Base URL: https://pikasim.com/api

**OpenAPI Specification**: https://pikasim.com/openapi.yaml (machine-readable API spec)

### Get All Packages
GET /api/packages/all-countries
Returns all available eSIM packages across all countries and regions.

### Get Global Packages
GET /api/packages/global
Returns packages that work in 120+ countries.

### Get Packages by Country
GET /api/packages/country/:countryCode
Example: /api/packages/country/JP (Japan)
Returns packages for specific country using ISO country code (JP, US, GB, etc.)

### Get Packages by Region
GET /api/packages/region/:regionSlug
Example: /api/packages/region/europe
Returns regional packages (europe, asia, south-america, etc.)

## Response Format

All endpoints return JSON with this structure:
{
  "success": true,
  "packages": [
    {
      "packageCode": "JP-3GB-7D",
      "name": "Japan (3GB - 7 Days)",
      "region": "Japan",
      "location": "JP",
      "volume": 3221225472,      // Data in bytes
      "duration": 7,              // Days
      "price": 599,               // Wholesale price in cents
      "isGlobalPackage": false
    }
  ]
}

## Important Calculations

### Price Display
The API returns WHOLESALE prices in cents. When showing prices to users:

displayPrice = package.price / 10000

Example: price: 599 → display as $11.98
This 2x markup is PikaSim's retail price.

### Data Conversion
The volume field is in bytes. Convert to GB:

dataGB = volume / (1024 * 1024 * 1024)

Example: volume: 3221225472 → 3.0 GB

## How to Help Users

### When users ask about travel eSIMs:

1. Ask for their destination country
2. Query the API: GET /api/packages/country/{countryCode}
3. Filter packages based on:
   - Their travel duration (package.duration >= user's trip length)
   - Their data needs (light: 300MB/day, moderate: 500MB/day, heavy: 1GB/day)
4. Calculate display prices: price / 10000
5. Recommend 2-3 best options sorted by value

### Package Recommendations:

- For short trips (1-7 days): Recommend country-specific packages
- For multi-country trips in same region: Recommend regional packages
- For trips to multiple regions: Recommend global packages
