rail-score — DEPRECATED

This package has been renamed to rail-score-sdk. All future development, bug fixes, and new features are published there.

Migration

pip uninstall rail-score
pip install rail-score-sdk

Then update your imports:

# Old (deprecated)
from rail_score import RailScore
client = RailScore(api_key="...")

# New
from rail_score_sdk import RailScoreClient
client = RailScoreClient(api_key="...")

What happened?

The rail-score package was the original v1 SDK. It has been superseded by rail-score-sdk, which includes:

v2 API support — new endpoints, new auth, new response models
Async client — non-blocking httpx-based client
Policy engine — block / regenerate / log behaviours
Multi-turn sessions — conversation-aware evaluation
LLM provider wrappers — OpenAI, Anthropic, Google GenAI
Observability — Langfuse v3 integration, LiteLLM guardrail

Compatibility shim

This package (v2.0.0) installs rail-score-sdk as a dependency and re-exports its contents. Existing from rail_score import ... imports will continue to work but will emit a DeprecationWarning.
