Web Fetch

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

bash

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.

bash

# 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

.
