This series is moving to the officially administered GX feed behind the scenes. GX does not publish the
p5/p95 envelope or transaction counts, so after the swap p5, p95, and txn_count will remain in the response but return null. Avoid building dependencies on these fields.400):
gpu_family— family-level daily indices (hopper,blackwell)gpu_group— daily GPU-level indices (h100,h200,a100,b200,b300)
gpu_group plus the mapped gpu_family; family-level rows have gpu_group: null.
index_type=blended_sigmoid (default) returns the transaction index — the sigmoid-weighted blend of the settled-trade leg and a posted-price leg. index_type=raw returns the transaction leg alone. Both are served EWMA-smoothed; there is no unsmoothed variant.
