Endpoint
POSThttps://x402-nvidia.vercel.app/api/rerank-qa-mistralWhen to prefer
Choose this endpoint when you need a dedicated Mistral-based reranking pass over QA candidates or retrieved passages, especially in RAG pipelines where passage ordering matters. Prefer over generic chat completions when you specifically need relevance scoring/reranking rather than generation.
