> Public plan catalog (plus billing {configured, mode}): CustomDomain™ API reference in the billing group. Covers parameters, request body and responses.

## `GET https://api.customdomain.ai/v1/plans`

The public plan catalog: `starter` ($10 a month, 10 new domains in any 12 months, the default for a new workspace, 14 day trial), `startup`, `growth`, and the contact-sales `premium` and `enterprise`. The retired `free` plan is not listed; a workspace created before it was retired keeps it until it subscribes. The figures above are the defaults: an operator can change a plan's `price_cents`, `domains_per_year` (and so `domains_per_month` and `quota`), `trial_days` and `hard_cap` without a release, so read them from this response rather than hard coding them. `billing.trial_days` is the default plan's trial.
