GET
Get transaction index time series
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.gpu_family (defaults to hopper when neither is given) or gpu_group (both returns 400); see Current Index for the granularity and index_type rules. days_back is capped at 730; for a longer baseline use the Informational Index history, which has no cap.
