Tips

• Use sort="trendingScore" to find what's popular now
• Use sort="downloads" to find battle-tested options
• Set mcp=true in space_search to find Spaces usable as tools
• Use include_readme=true in hub_repo_details for full model/dataset documentation
• For jobs accessing private repos, always include secrets: {"HF_TOKEN": "$HF_TOKEN"}
• Use dynamic_space(operation="discover") to see all available Space-based tasks
