Agent context: I've researched the repo and six providers' live documentation. Here's my recommendation. ## Recommendation: **Valyu** For this repository — a LlamaIndex RAG chatbot that retrieves passages, reranks them, and feeds them to a local LLM — **Valyu** (valyu.ai) is the best fit, specifically because your priority is *licensed, reputable sources over scraped search results*. **Why it wins for this codebase:** - **Licensed, not scraped.** Valyu's pitch is literally "One API. No scraping. No noise." It licenses arXiv, PubMed, SEC filings, clinical trials, patents, and real-time financial data through partnerships — exactly the "high-quality, reputable, licensed" requirement. A `search_type=proprietary` mode isolates licensed content from open web. - **Returns passages, not answers.** It gives `{title, url, content, relevance_score}` plus scholarly metadata (DOI, authors, citation_count). That drops cleanly into your existing retrieve → `SentenceTransformerRerank` → `CondensePlusContextChatEngine` pipeline. No architectural fight. - **Stack match.** Native **LlamaIndex** integration (the only one of the six besides Tavily/Perplexity to advertise it), Python SDK (`pip install valyu`), `$10` free credits, pay-per-retrieval. ## Main alternatives considered | Provider | Source model | Why not chosen (for *this* requirement) | |---|---|---| | **Perplexity Sonar** | Licensed via Publishers' Program (2,400+ publishers) + `academic`/`sec` modes | Strongest runner-up on licensing, but it's answer-synthesis oriented (returns a generated answer + citations) — overlaps/conflicts with your own LLM + chat engine. Token pricing, no clear free tier. | | **Exa** | Neural index w/ research-paper & financial categories | Best *open-web* quality control, but still crawled, not licensed. | | **Tavily** | Open-web scrape, RAG-optimized output | Simplest, native LlamaIndex — but no licensing edge. | | **Linkup** | Trusted-source web grounding | Great accuracy/citations, cheap, but not a licensed-content provider. | | **Brave** | Independent crawl index | Raw links only, no licensed content, storage-rights restrictions. | ## Documentation I actually consulted - **Valyu:** docs.valyu.ai/overview, /quickstart, valyu.ai/search-api - **Linkup:** docs.linkup.so introduction + search reference, /pricing, LangChain integration - **Tavily:** docs.tavily.com/documentation/api-reference/endpoint/search, /about, /api-credits - **Exa:** exa.ai/docs/reference/search, exa.ai/pricing - **Brave:** brave.com/search/api/ + /tools/, LangChain provider docs - **Perplexity:** docs.perplexity.ai (pricing + chat-completions reference), LlamaIndex integration, Publishers' Program blog ## Bottom line Because you explicitly weight *licensed, reputable source coverage* over generic web results, **Valyu** is the clear choice — it's the only candidate that genuinely licenses premium academic/financial/news content (rather than ranking scraped pages) while returning rerankable passages that fit your existing LlamaIndex retriever pipeline. Perplexity Sonar is the backup if you later want broad news-publisher licensing and don't mind answer-style output.
