Three guardrails between your app and the model
One proxy hop gives you cost control, structural safety and version confidence — with no SDK rewrite.
Silent Drift Protection
Auto-validates output JSON schemas against breaking LLM API updates. Triggers instant Slack alerts or failover routing.
Context Window Optimizer
In-line token pruner strips whitespace, system prompt redundancy, and duplicate RAG memory chunks without quality loss.
Shadow Regression Testing
Runs live user prompt samples against new model versions in the background with automated compliance scoring.
Install, swap, ship — in one language at a time
Node and Python wrappers set the proxy headers for you and return token savings on every response. Each tab is a single clean language; copy takes only the active tab.
