Error Handling

Rate Limiting

• HKO API does not enforce strict rate limits
• Recommended: Cache responses for 10-15 minutes
• If API fails, wait 5 seconds and retry once

API Failures

• If current weather fails: Return forecast only with error notice
• If forecast fails: Return current weather only with error notice
• If both fail: Return friendly error message suggesting retry

Timeout

• Set timeout to 10 seconds per request
• HKO servers are generally reliable but can be slow during peak times

Scripts

See scripts/fetch-weather.sh for a ready-to-use fetcher with Traditional Chinese output.
