GET
Get transaction index values on a specific date
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.
Returns the latest published value on or before as_of_date, so weekends and holidays resolve to the prior business day. Takes either gpu_family or gpu_group (both returns 400) — see Current Index for the granularity rules.
