Transaction Aggregates

Transaction Aggregates: Blends

Returns privacy-safe blends of settled GPU transactions, paginated. Each row is a volume-weighted blend of settled transactions from the same (GPU model, region group, contract type, reserved tenor) bucket, adjacent by date. Only the volume-weighted price is published (no median/min/max), and rows are NOT additive: neighbouring rows can share underlying transactions, so never SUM total_gpu_count / total_gpu_hours across rows.

Privacy-safe blends of settled GPU transactions, paginated. Each row is a volume-weighted blend of settled transactions from the same (GPU model, region group, contract type, reserved tenor) bucket, adjacent by date.

Only the volume-weighted price is published. Rows are not additive — neighbouring rows can share underlying transactions, so never SUM total_gpu_count / total_gpu_hours across rows.

Example
