## GET /api/v2/products/domains/{tld}

**Get TLD pricing and registry requirements**

Return current pricing, orderable periods, configurable options, and server-derived registry requirements for one TLD. Start with `GET /api/v2/products/domains`, then call this endpoint for the selected `tlds[].tld` value. Call this before `POST /api/v2/orders` when building a registration or transfer payload. Use `registryRequirements.registration[]` for `action: register`, `registryRequirements.transfer[]` for `action: transfer`, and copy any `acceptedTermsKey` values into the domain item `acceptedTerms[]` array. Only the `domainPricing[].years` entries returned here are supported for multi-year orders or renewal cost displays; unsupported periods are omitted, not represented by a generated range.

### Related Endpoints

- `GET /api/v2/domains/availability`: Check domain availability
- `POST /api/v2/domains/availability`: Check bulk domain availability
- `POST /api/v2/orders/preview`: Preview an order

### Headers

- `Accept`: application/json
- No authorization header required.

### Parameters

- `tld` (path, string, required): TLD suffix from `GET /api/v2/products/domains` `tlds[].tld`. The route accepts `se` or `.se`; examples use `se` because path segments normally omit the dot. Example: `fi`
- `locale` (query, string): Optional locale for configurable-option labels when the upstream catalog provides localized labels. Example: `en`

### Request Example

```bash
curl -X GET "https://cloud.hostup.se/api/v2/products/domains/fi" \
  -H "Accept: application/json"
```

### Response Schema

- `tld` (string, optional): Canonical TLD suffix with a leading dot. Example: `.se`
- `register` (null, optional): One-year new-registration price. `null` means this action is not currently priced for the TLD.
- `transfer` (null, optional): One-year inbound transfer price. `0` means free; `null` means not configured.
- `renew` (null, optional): One-year renewal price for existing domains using this TLD.
- `redemption` (null, optional): One-year redemption or restore-from-expired price when configured.
- `billing` (object, optional): Canonical billing summary for the one-year registration price. Use `domainPricing[]` for multi-year pricing.
- `billing.amount` (number, required) Example: `199`
- `billing.currencyCode` (string, required) Example: `SEK`
- `billing.billingCycle` (string,null, required): Canonical billing cycle. VPS services with `isPayg: true` still report `monthly` for summary display; use `isPayg` to distinguish PAYG Cloud VPS from fixed-cycle VPS. Example: `annually`
  Allowed values: monthly, quarterly, semiannually, annually, biennially, triennially, free, 
- `billing.isPayg` (boolean, required): For VPS service/order billing, true means pay-as-you-go Cloud VPS and false means fixed-cycle/prepaid VPS. Non-VPS resources normally return false. Example: `false`
- `billing.periodYears` (integer,null, optional) Example: `1`

- `domainPricing[].transfer` (null, optional)
- `domainPricing[].renew` (null, optional)
- `domainPricing[].redemption` (null, optional)
- `configurableOptions` (array<object>, optional): Low-level configurable option metadata for registry-required domain fields. Prefer `registryRequirements` for order-building decisions.
- `registryRequirements` (object, optional): Server-derived, human-readable requirements for registration and transfer payloads. Consumers should not infer TLD rules client-side.
- `registryRequirements.registration` (array<object>, optional): Fields and terms required when `items[].action` is `register`.
- `registryRequirements.registration[].key` (string, required) Example: `eppCode`
  Allowed values: eppCode, phoneNumber, registrationIdentifier, companyRegistrationNumber, birthDate, registrantCountry, registrantType, useDomicile, acceptedTerms, nameservers
- `registryRequirements.registration[].label` (string, required) Example: `Authorization code`

  Allowed values: register, transfer, both
- `registryRequirements.registration[].registrantType` (string, required) Example: `any`

- `registryRequirements.transfer[].label` (string, required) Example: `Authorization code`

- `registryRequirements.transfer[].appliesTo` (string, required) Example: `transfer`
  Allowed values: register, transfer, both
- `registryRequirements.transfer[].registrantType` (string, required) Example: `any`
  Allowed values: any, private, organisation
- `registryRequirements.transfer[].allowedCountryCodes` (array,null, optional) Example: `null`
- `registryRequirements.transfer[].allowedRegistrantTypes` (array,null, optional) Example: `null`
- `registryRequirements.transfer[].alternativeRequirementKey` (string,null, optional) Example: `null`
- `registryRequirements.transfer[].acceptedTermsKey` (string,null, optional) Example: `se_registration_terms`
- `registryRequirements.transfer[].reason` (string, required) Example: `An authorization code is required to transfer this domain.`
- `registryRequirements.countryEligibility` (object, optional): Registrant-country restrictions for this TLD, when any.
