History coverage and sources

Each point contains timestamp, priceUsd and available additional metrics. Dates use UTC. The all range means the entire locally stored history; its beginning may differ from the coin's launch date.

Check meta.coverageStart, meta.coverageEnd, meta.source, meta.gaps, meta.truncated and meta.isDemo. Request smaller intervals for truncated responses. USD and USDT quotes are stored separately.
