- The upstream /volumes endpoint is undocumented and does not agree with the 24-hour bucket totals, so the two volume figures are shown separately rather than blended into one number.
- Some items share a connected buy limit with their other dose or charge variants — prayer potions, for instance, draw on one pool across all four doses. The API does not publish those connections, so the limit shown here is the per-item figure and may overstate what you can actually buy.
