The previous 30 complete UTC days supply the historical baseline; at least seven complete samples are required. The same elapsed UTC-day fraction excludes the open minute. Full-day means and trailing 24h comparisons remain separate. The delta is USD. A zero-baseline ratio is null. Current-day coverage cannot certify historical or trailing coverage. Requires md.read and the standard 120 requests/minute budget. This read-only beta endpoint reads a shared native VM observation; a request does not initiate a third-party market-data request.
