Which Web Search API gives the cleanest Markdown output for local RAG parsing?

Web search APIs are essential for grounding local LLMs, but feeding raw HTML or messy JSON snippets wrecks context windows and reasoning in 8B-70B models. I want a clean web-grounding loop without building a heavy scraping middleware (like Playwright + Trafilatura). I'm looking for something that natively handles the heavy lifting and returns ready-to-ingest, noise-free Markdown. Here is my current shortlist: Brave Search (LLM Context API): Has a dedicated endpoint returning relevance-ranked, pre-formatted Markdown chunks.
