Polar as a merchant of record, ready for Paykit.BillingStack.

One call, no bindings to wire: Polar() returns the Provider the catalog needs, with the tier → product mapping and the price the catalog states, so BillingStack can refuse a mapping that disagrees at deploy time.

It owns tax, receipts and payments; paykit keeps the entitlement. Polar’s benefits are written as a consequence of a tier change and never read back — check() answers from paykit’s own read model.

Polar is the one vendor with no Alchemy package, which is why paykit publishes this one. It is paykit-shaped on purpose: a general provider would need its own users and release train to justify the same maintenance.

});

yield* Paykit.BillingStack("Billing", { providers: [polar], catalog });
