Date: November 20, 2025 We’re excited to introduce Exa Deep - a new search type that finds better results by running multiple searches at once and gives you high-quality summaries for each result. You can send just one query (we’ll create variations automatically) or provide your own query variations using the queryVariants parameter for even better results.
Deep search is available on our API Playground. Try Deep search in the dashboard →

How Deep Search Works

When you use Deep search, here’s what happens:
  1. Query Expansion: If you only send one query, we automatically create variations. If you send query variations yourself using queryVariants, we use those instead.
  2. Parallel Search: We search for your main query and all variations at the same time
  3. Smart Ranking: We combine and rank all results to give you the most relevant ones
  4. Summary Generation: Each result gets a detailed, accurate summary
Using Deep search is simple - just add type="deep" to your search requests. You can also add queryVariants for even better results: Basic Deep Search: 
curl -X POST https://api.exa.ai/search \
  -H "x-api-key: EXA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "blog post about AI",
    "type": "deep"
  }'
Deep Search with Query Variations: 
curl -X POST https://api.exa.ai/search \
  -H "x-api-key: EXA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "blog post about AI",
    "queryVariants": ["AI blogpost", "machine learning blogs"],
    "type": "deep"
  }'
