Web Fetch

Fetch and analyze content from one or more URLs using Gemini 2.5 Flash with URL context.

nansen web fetch https://nansen.ai --question "What products does Nansen offer?"
nansen web fetch --url https://example.com --url https://other.com --question "Compare these two sites"
nansen web fetch https://docs.uniswap.org/contracts/v4/overview --question "What changed in v4?"

Positional args and --url flags can be combined — all become URLs to fetch.

Flag Values Default Purpose
--url URL — URL to fetch (repeatable for multiple URLs, up to 20)
--question string required Question to answer about the URL content
--pretty flag off Human-readable JSON

Returns:

  • analysis — AI-generated answer to your question
  • retrieved_urls — URLs successfully fetched
  • failed_urls — URLs that could not be retrieved

Tip: Combine with web search — search first to find relevant URLs, then fetch to get full content.

# Find and analyze in two steps
nansen web search "uniswap v4 launch" --num-results 3 --fields link
nansen web fetch https://blog.uniswap.org/... --question "What are the key changes?"

Note: 30s timeout. Paywalled or bot-blocked pages may appear in failed_urls.
