+- **Page Ranges**: Use `{"start": 0, "end": 4}` (0-based, end inclusive) and `{"start": 10}` (to end)
 - **Multiple Operations**: Some tools require multiple API calls (one per page range/operation)
 - **Error Handling**: API returns 400 with detailed errors when parameters are invalid
 - **Testing Strategy**: Focus on integration tests with live API rather than unit test mocking

+# Pull Request: Add Missing Direct API Tools
+
+## Summary
+This PR adds 8 new direct API methods that were missing from the Python client, bringing it to feature parity with the Nutrient DWS API capabilities.
+
+## New Tools Added
+
+### 1. Create Redactions (3 methods for different strategies)
+- `create_redactions_preset()` - Use built-in patterns for common sensitive data
+  - Presets: social-security-number, credit-card-number, email-address, international-phone-number, north-american-phone-number, date, time, us-zip-code
+- `create_redactions_regex()` - Custom regex patterns for flexible redaction
+- `create_redactions_text()` - Exact text matches with case sensitivity options
+
+### 2. PDF Optimization
+- `optimize_pdf()` - Reduce file size with multiple optimization options:
+  - Grayscale conversion (text, graphics, images)
+  - Image optimization quality (1-4, where 4 is most optimized)
+  - Linearization for web viewing
+  - Option to disable images entirely
+
+### 3. Security Features
+- `password_protect_pdf()` - Add password protection and permissions
+  - User password (for opening)
+  - Owner password (for permissions)
+  - Granular permissions: print, modification, extract, annotations, fill, etc.
+- `set_pdf_metadata()` - Update document properties
+  - Title, author, subject, keywords, creator, producer
+
+### 4. Annotation Import
+- `apply_instant_json()` - Import Nutrient Instant JSON annotations
+  - Supports file, bytes, or URL input
+- `apply_xfdf()` - Import standard XFDF annotations
+  - Supports file, bytes, or URL input
+
+## Implementation Details
+
+### Code Quality
+- ✅ All methods have comprehensive docstrings with examples
+- ✅ Type hints are complete and pass mypy checks
+- ✅ Code follows project conventions and passes ruff linting
+- ✅ All existing unit tests continue to pass (167 tests)
+
+### Architecture
+- Methods that require file uploads (apply_instant_json, apply_xfdf) handle them directly
+- Methods that use output options (password_protect_pdf, set_pdf_metadata) use the Builder API
+- All methods maintain consistency with existing Direct API patterns
+
+### Testing
+- Comprehensive integration tests added for all new methods (28 new tests)
+- Tests cover success cases, error cases, and edge cases
+- Tests are properly skipped when API key is not configured
+
+## Files Changed
+- `src/nutrient_dws/api/direct.py` - Added 8 new methods (565 lines)
+- `tests/integration/test_new_tools_integration.py` - New test file (481 lines)
+
+## Usage Examples
+
+### Redact Sensitive Data
+```python
+# Redact social security numbers
+client.create_redactions_preset(
+    "document.pdf",
+    preset="social-security-number",
+    output_path="redacted.pdf"
+)
+
+# Custom regex redaction
+client.create_redactions_regex(
+    "document.pdf",
+    pattern=r"\b\d{3}-\d{2}-\d{4}\b",
+    appearance_fill_color="#000000"
+)
+
+# Then apply the redactions
+client.apply_redactions("redacted.pdf", output_path="final.pdf")
+```
+
+### Optimize PDF Size
+```python
+# Aggressive optimization
+client.optimize_pdf(
+    "large_document.pdf",
+    grayscale_images=True,
+    image_optimization_quality=4,
+    linearize=True,
+    output_path="optimized.pdf"
+)
+```
+
+### Secure PDFs
+```python
+# Password protect with restricted permissions
+client.password_protect_pdf(
+    "sensitive.pdf",
+    user_password="view123",
+    owner_password="admin456",
+    permissions={
+        "print": False,
+        "modification": False,
+        "extract": True
+    }
+)
+```
+
+## Breaking Changes
+None - all changes are additive.
+
+## Migration Guide
+No migration needed - existing code continues to work as before.
+
+## Checklist
+- [x] Code follows project style guidelines
+- [x] Self-review of code completed
+- [x] Comments added for complex code sections
+- [x] Documentation/docstrings updated
+- [x] No warnings generated
+- [x] Tests added for new functionality
+- [x] All tests pass locally
+- [ ] Integration tests pass with live API (requires API key)
+
+## Next Steps
+After merging:
+1. Update README with examples of new methods
+2. Consider adding more tools: HTML to PDF, digital signatures, etc.
+3. Create a cookbook/examples directory with common use cases
