Tavily
Tavily is a sensible default for developers who need agents to search and read the live web without building scraping and ranking themselves. Teams with very high query volume, or that need full raw SERP data and control over sources, should price it against running their own search stack.
Pros
- Search, extract, crawl, map and research behind one API key
- Results come chunked and cleaned for model context
- 1,000 free credits a month without a card
- Built-in PII and prompt-injection filtering
Cons
- Advanced requests consume more credits, which makes costs harder to predict
- Requests stop outright when monthly credits run out on the free tier
- Now owned by Nebius, so roadmap and terms may shift with the parent
