Guidelines

1. No rate limits documented: But be respectful, add delays for bulk fetching
2. Use jq for filtering: Filter JSON responses to extract needed data
3. Cache results: Stories don't change frequently, cache when possible
4. Batch requests carefully: Each item requires a separate API call
5. Handle nulls: Some fields may be null or missing (e.g., url for Ask HN)
6. Unix timestamps: All times are Unix timestamps, convert as needed
