1. The JSON Reliability Problem
When working with LLMs, one of the most common pain points is receiving malformed JSON responses. Whether it's missing closing brackets, unescaped characters, or truncated output, these defects can break downstream processing and require expensive retry logic.
2. How Response Healing Works
Our Response Healing system operates at the API gateway level, intercepting and repairing malformed responses before they reach your application. It uses a combination of structural analysis, context-aware repair heuristics, and lightweight validation models to fix common JSON defects in real-time.
Repair Strategies
The system employs multiple repair strategies including bracket completion, string escape normalization, truncation recovery, and schema-guided reconstruction. Each strategy is applied based on the detected defect type, ensuring minimal latency overhead while maximizing repair accuracy.
3. Results and Performance
In production testing across millions of API calls, Response Healing has reduced JSON defect rates by over 80%. The median latency overhead is under 5ms, making it virtually transparent to end users. This feature is now available to all PP API customers at no additional cost.
