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 questionretrieved_urls— URLs successfully fetchedfailed_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.
