Why Teams Switch to Valyu

​
1. Access Data Web Search Can’t Reach

Tavily searches the web. Valyu searches the web AND proprietary data sources:
  • 37M+ PubMed papers - Biomedical literature behind paywalls
  • 3M+ SEC filings - 10-K, 10-Q, 8-K with full-text search
  • 500K+ clinical trials - Study protocols, eligibility, outcomes
  • 8M+ patents - Prior art and IP research
  • Real-time financial data - Stock prices, earnings, fundamentals

​
2. Better Results for Professional Use Cases

For AI agents working in finance, healthcare, or research, web search alone isn’t enough: 
from valyu import Valyu

valyu = Valyu()

# Search across web AND proprietary sources
response = valyu.search(
    "CAR-T cell therapy clinical outcomes 2024",
    search_type="all",  # Web + proprietary
    max_num_results=20
)

​
3. Same Simple API

Switching from Tavily is straightforward: 
# Valyu - drop-in replacement
from valyu import Valyu

valyu = Valyu()
response = valyu.search("your query here")
