meter event name
The name of the usage event a metered recurring price meters — 'api_request', 'gb_transferred', 'active_user'. A qualifier of `recurring_price` (cardinality one), present only when `usage_type` is metered. A free literal: meter names are open seller-defined identifiers, not an enumerable vocabulary (the b76 hs_tariff_code / b75 trade_identifier literal-anchor precedent).
Meter event name is free text, written for one product alone and never shared as a category.
It is a qualifier of recurring price — it has meaning only inside a recurring price statement, one per statement, never on its own. It belongs with recurring price to subscription & financing — one facet of a product.
It is answered inside every recurring price statement, not as a standalone question on a kind.
