## About

## What it does
Crypto Market Cap returns the global cryptocurrency market snapshot in a chosen quote currency. Send `vs` as `usd`, `eur`, `gbp`, `btc`, or `eth`, and get back the current market data in that denomination.

The response includes `source`, `vs`, `totalVolume`, `btcDominance`, `ethDominance`, `totalMarketCap`, `marketCapChange24h`, and `activeCryptocurrencies`. Numeric fields may be null when the upstream source does not have a value available, so you can handle missing market data without guessing.

Use Crypto Market Cap when you need to show a dashboard, drive portfolio analytics, or annotate a crypto summary with current dominance and capitalization figures. Because the output is already normalised around a single `vs` currency, it fits cleanly into charts, market overviews, and comparison views.

It is a lightweight read-only endpoint for applications that need a fast global crypto market reference rather than per-asset pricing or exchange order books.
