Coin Market Chart Range

by Coin market chart for a time in Markets & finance

x402 APIPassing, checked 43 min ago

Price, market cap and volume series for a coin over an ARBITRARY time window: `from`/`to` as unix seconds or ISO dates, or `lookback` ("6h", "3d", "2w") ending now. Granularity is automatic upstream: 5-minute points for a window of 1 day or less, hourly up to 90 days, daily beyond. The windowed sibling of crypto-history (which counts days back from now): use it to align with a specific event, a filing date or another series.
