    Why it is in this group

    • The name "compare_assets" says "compare": a word for reading.
    Description, as the server wrote it
    Compare two Marketcaper assets and return relative size or a supported hypothetical price-at-size scenario, the canonical pair URL, and an optional hosted image URL. Hosted images are PNG, generated on demand, share a 10 images/day/IP limit, and may require a longer timeout than the MCP JSON call. Check the input observation times and always cite the returned source_url when using the data.
