}Get supply and demand time series
Get aggregated supply (issuances) and demand (retirements) data over time.
Returns a time series where each data point contains both issuance and retirement quantities for a given period, plus overall totals. Useful for building supply vs. demand comparison charts.
Aggregation levels:
monthly: Period formatYYYY-MM(e.g.,2024-06)quarterly: Period formatYYYY-Q#(e.g.,2024-Q2)yearly: Period formatYYYY(e.g.,2024)
The current incomplete period is excluded to avoid misleading partial data.
Filters: All standard project and credit filters apply, letting you analyze supply/demand for specific registries, countries, categories, or date ranges.
