Tavily: Web Data, Pricing and Evaluation Guide

What does Tavily do?

Tavily offers search, extraction, crawling, mapping and research endpoints for applications and agents that need web context.

Who should consider it?

Developers adding attributable web research to an application rather than buying a standalone chat interface.

How much does it cost?

Researcher provides 1,000 free monthly credits. Official documentation lists Project at $30 per month for 4,000 credits and pay-as-you-go at $0.008 per credit. Basic search costs one credit per request; advanced search costs two. Extraction, crawling and research have separate consumption rules, so one research task is not necessarily one credit.

How can you evaluate it on a small task?

Prepare five public questions with known primary sources, including one outdated announcement and one question the sources do not answer. Request source URLs and dated supporting passages. Evaluate retrieval separately from the final generated answer: a correct document can still be summarized incorrectly.

What should a useful result pass?

• Every material answer claim points to a retrieved passage that actually supports it.
• The outdated announcement is distinguished from a current policy.
• The unanswered question remains unresolved rather than receiving an invented answer.
• Log credits for the whole research task, not merely the first search call.

What are the limits and data considerations?

Retrieval does not eliminate unsupported model conclusions. Queries are sent to an external provider; remove private customer details before experimentation. Review pagination, request limits and retry behavior in the endpoint documentation before enabling unattended loops.

Which alternatives should you compare?

Compare Firecrawl for URL-led collection and extraction. Compare Perplexity when an analyst wants an interactive research interface instead of building an API integration. Use the same questions and source requirements when evaluating different approaches.
