Base coin price mini-endpoint for major tokens only. Returns spot prices and 24h stats for well-known tickers like btc, solana, eth, xmr, ltc and other large-cap coins, never microcaps. Pass an optional ticker to get a single-coin 24h snapshot with price, symbol, changeRate, changePrice, high and low, or omit ticker to receive a compact basket of top tokens in a fixed order. Cost: 0.001 USDC per request.
