Fetch live cryptocurrency prices with zero API keys — CoinGecko's public endpoints primary, Coinbase spot fallback, via plain curl. Use when asked what's bitcoin at, ETH price in euros, how's the crypto market today, or price of some altcoin. Produces the current price with 24h context, the source and timestamp, the rerunnable command, and the volatility caveat that crypto answers must carry.

Crypto prices are the most-asked live number after weather, and two services answer keylessly: CoinGecko's public API (thousands of coins, market context, any quote currency) and Coinbase's spot endpoint (fast, reliable, majors only). This skill fetches, adds the 24-hour context that turns a number into information, and carries the caveat every crypto answer owes: this number is already stale, and it is not advice.
Ask for these if not provided:
