# Prices Csv

> Convenience GET that streams as-of prices straight to CSV (no string query to compose).

Same edge contract and bitemporal as-of semantics as ``POST /india/exports``; the constraints are
structured query params instead of a string query. Handy for ``curl``/spreadsheet ``=IMPORTDATA``.
