Real crypto market data in one batched call: price, market cap, market-cap rank, 24h volume/high/low/change, circulating/total/max supply, and all-time-high with date -- for BTC, ETH, SOL, and 17+ other major coins by ticker. Richer than a plain price feed: most stock-data APIs' crypto tickers report null market cap. From CoinGecko. $0.0025/call.

We sent a real GET request to this endpoint and it answered 402 with payment requirements we could parse.
