Limitations

• Submission limit: LeetCode's public API limits userSubmissions and userAcSubmissions to 20 items. Use userSummary for aggregate stats.
• Rate limiting: Implemented to avoid overloading LeetCode's servers
• Premium content: Some content may require LeetCode Premium subscription

Notes

• Problem content is cleaned and formatted from HTML to readable text
• HTML entities (\u003C, <, etc.) are properly decoded
• Solutions include video and code playground links
• Heatmaps include daily submission counts organized by year/month/day

Cost

This Actor uses minimal compute resources as it only makes HTTP requests to LeetCode's GraphQL API.
