Initialization Options

fallom.init(
    api_key="your-api-key",      # Or use FALLOM_API_KEY env var
    base_url="https://spans.fallom.com",  # Or use FALLOM_BASE_URL env var
    capture_content=True         # Set False for privacy mode
)

​
Privacy Mode

For companies with strict data policies, disable prompt/completion capture:
# Via parameter
fallom.init(capture_content=False)

# Or via environment variable
FALLOM_CAPTURE_CONTENT=false
In privacy mode, Fallom still tracks:
CapturedNot Captured
✅ Model used❌ Prompt content
✅ Token counts❌ Completion content
✅ Latency
✅ Session/config context
✅ Prompt key/version (metadata only)
