Exa vs Tavily

Tavily and Exa both offer web search APIs optimized for AI agents, but with distinct strengths. Tavily excels at real-time, secure web search: its /research endpoint achieved SOTA on SimpleQA and Document Relevance, and its Dynamic Filtering (inspired by Anthropic's PTC) lets the model program search filters at runtime. Exa, meanwhile, has deprecated its older /research endpoint in favor of /search with type deep-reasoning, and its latest Exa Agent supports natural language queries with effort modes. Tavily offers built-in PII, prompt injection, and malicious source filters, while Exa provides zero data retention and SOC 2 Type II certification. For content extraction, Tavily's crawling and cleaning produce LLM-ready text; Exa's token-efficient Highlights reduce token consumption by up to 90% with maxCharacters control. Exa's structured output extraction across 70M+ companies is a standout for sales intelligence. Both support semantic search, but Exa's offering includes code and docs. Tavily's x402 integration (May 2026) is unique: agents pay per query with a USDC wallet on Base, no API key required. In latency, Exa's Instant Search claims sub-150ms vs Tavily's 180ms p50. Exa's Deep (4-12s) and Deep Reasoning (12-40s) offer multi-step research; Tavily's /research is faster but less deep. Peerbound switched from Exa to Tavily, improving accuracy from 2/10 to 10/10, underscoring Tavily's relevance.

Tavily offers a freemium model with a free tier (1K requests/month) and pay-as-you-go after that; Exa increased its free tier to 20K requests/month (March 2026). Exa's paid pricing is usage-based: search with contents at $7/1K, Deep at $12/1K, and Deep Reasoning at $15/1K. Tavily's pricing is not explicitly stated in the static data, but it is described as freemium with additional costs for scaling. Tavily's x402 integration (May 2026) introduces a novel pay-per-query model using USDC on Base, potentially reducing upfront costs for agent experiments. Exa's simplified pricing (March 2026) makes cost predictable for heavy extractors, while Tavily's caching and indexing (300M+ monthly capacity, 99.99% uptime) can lower effective per-request costs at scale. For budget-constrained teams, Exa's larger free tier is attractive; for production enterprises with high volume, Tavily's SLA and caching may deliver better price performance.
