For example `sfw-only` indicates that only\n * \"Safe For Work\" content is encouraged on this relay. This\n * relies on assumptions of what the \"work\" \"community\"\n * feels \"safe\" talking about. In time, a common set of tags\n * may emerge that allow users to find relays that suit\n * their needs, and client software will be able to parse\n * these tags easily. The `bitcoin-only` tag indicates that\n * any _altcoin_, _\"crypto\"_ or _blockchain_ comments will\n * be ridiculed without mercy.\n * @param posting_policy is a link to a human-readable page\n * which specifies the community policies for the relay. In\n * cases where `sfw-only` is True, it's important to link to\n * a page which gets into the specifics of your posting\n * policy.\n\n * The `description` field should be used to describe your\n * community goals and values, in brief. The\n * `posting_policy` is for additional detail and legal\n * terms. Use the `tags` field to signify limitations on\n * content, or topics to be discussed, which could be\n * machine processed by appropriate client software.\n */\nexport interface CommunityPreferences {\n language_tags: string[]\n tags: string[]\n posting_policy: string\n}\n\nexport interface Amount {\n amount: number\n unit: 'msat'\n}\nexport interface PublicationAmount extends Amount {\n kinds: number[]\n}\nexport interface Subscription extends Amount {\n period: number\n}\nexport interface Fees {\n admission: Amount[]\n subscription: Subscription[]\n publication: PublicationAmount[]\n}\n/**\n * Relays that require payments may want to expose their fee\n * schedules.\n */\nexport interface PayToRelay {\n payments_url: string\n fees: Fees\n}\n\n/**\n * A URL pointing to an image to be used as an icon for the\n * relay.

For example `sfw-only` indicates that only\n * \"Safe For Work\" content is encouraged on this relay. This\n * relies on assumptions of what the \"work\" \"community\"\n * feels \"safe\" talking about. In time, a common set of tags\n * may emerge that allow users to find relays that suit\n * their needs, and client software will be able to parse\n * these tags easily. The `bitcoin-only` tag indicates that\n * any _altcoin_, _\"crypto\"_ or _blockchain_ comments will\n * be ridiculed without mercy.\n * @param posting_policy is a link to a human-readable page\n * which specifies the community policies for the relay. In\n * cases where `sfw-only` is True, it's important to link to\n * a page which gets into the specifics of your posting\n * policy.\n\n * The `description` field should be used to describe your\n * community goals and values, in brief. The\n * `posting_policy` is for additional detail and legal\n * terms. Use the `tags` field to signify limitations on\n * content, or topics to be discussed, which could be\n * machine processed by appropriate client software.\n */\nexport interface CommunityPreferences {\n language_tags: string[]\n tags: string[]\n posting_policy: string\n}\n\nexport interface Amount {\n amount: number\n unit: 'msat'\n}\nexport interface PublicationAmount extends Amount {\n kinds: number[]\n}\nexport interface Subscription extends Amount {\n period: number\n}\nexport interface Fees {\n admission: Amount[]\n subscription: Subscription[]\n publication: PublicationAmount[]\n}\n/**\n * Relays that require payments may want to expose their fee\n * schedules.\n */\nexport interface PayToRelay {\n payments_url: string\n fees: Fees\n}\n\n/**\n * A URL pointing to an image to be used as an icon for the\n * relay.
