Filter parameters must be passed through the params dict with dot notation for range filters. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
The API returns nested data (details.strike_price) which gets flattened to details_strike_price. Updated presets to use correct flattened names so strike_price and contract_type are included in output. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
