marketcaper/marketMarketcaper lets AI clients compare crypto, stocks, fiat currencies, GDP, and billionaire net worth on one scale. It turns abstract market-cap differences into concrete what-if scenarios like “What price would BTC be at ETH’s market cap?” or “What price would NVDA be at Elon Musk’s net worth?” Valid public Marketcaper pair pages are directly readable HTML, but the MCP endpoint is the official structured path for deterministic JSON, canonical source URLs, citation text, and hosted comparison images. That makes it useful for AI assistants, automation tools, and agent workflows that need both numbers and attribution. The server is deliberately narrow and citation-first. It focuses on single-asset snapshots, pair comparisons, and ready-to-publish comparison packs rather than bulk extraction. For valid comparisons, clients can also request a hosted PNG image that works well for social posts, alerts, and content workflows.
