Authentication

Current Setup

Most API endpoints are currently public (no authentication required) for development.

Adding Authentication (Production)

For production deployments, add authentication:

import requests

# Get authentication token
def get_auth_token(username, password):
    """Login and get JWT token"""
    url = f"{URLS['backend']}/auth/login/"

    response = requests.post(url, json={
        'username': username,
        'password': password
    })
    response.raise_for_status()

    return response.json()['token']

# Use token in requests
token = get_auth_token('your_username', 'your_password')

headers = {
    'Authorization': f'Bearer {token}'
}

response = requests.get(f"{URLS['backend']}/admin0/", headers=headers)

---

Error Handling

Standard Error Responses

All APIs return standard HTTP status codes:

• 200 - Success
• 400 - Bad Request (invalid parameters)
• 401 - Unauthorized (authentication required)
• 403 - Forbidden (insufficient permissions)
• 404 - Not Found (resource doesn't exist)
• 500 - Internal Server Error

Example Error Handling

def safe_api_call(url, params=None):

Quick Reference

Common Tasks

Task	API	Endpoint
Get latest forecast	FastAPI	GET /api/fast/merged-forecast/latest/
Get forecast dates	FastAPI	GET /api/fast/merged-forecast/dates/
Get countries	Django	GET /api/admin0/
Get monitoring stations	Django	GET /api/monitoring-stations/
Get rivers	Django	GET /api/rivers/
Get lakes	Django	GET /api/water-bodies/
Get vector tiles	TiPg	GET /tipg/collections/{id}/tiles/{z}/{x}/{y}
API documentation	Django	GET /api/schema/swagger-ui/

Performance Tips

1. Use FastAPI for large GeoJSON: 2-3x faster than Django for forecast data
2. Cache responses: Store frequently accessed data locally
3. Use pagination: Limit large queries with ?limit= parameter
4. Filter early: Use country= or bbox= to reduce response size
5. Use vector tiles: For map visualization, MVT tiles are 90% smaller than GeoJSON
6. Check headers: Monitor X-Response-Time and X-Cache-Hit headers
