Types

type Admission

type Admission struct {
	Amount int    `json:"amount"`
	Unit   string `json:"unit"`

type Fees

type Fees struct {
	Admission    []Admission    `json:"admission,omitempty"`
	Subscription []Subscription `json:"subscription,omitempty"`
	Publication  []Publication  `json:"publication,omitempty"`
}

Fees defines the fee structure used for a paid relay.

type Limits

type Limits struct {
	// MaxMessageLength is the maximum number of bytes for incoming JSON
	// that the relay will attempt to decode and act upon. When you send large
	// subscriptions, you will be limited by this value. It also effectively
	// limits the maximum size of any event. Value is calculated from [ to ] and
	// is after UTF-8 serialization (so some unicode characters will cost 2-3
	// bytes). It is equal to the maximum size of the WebSocket message frame.
	MaxMessageLength int `json:"max_message_length,omitempty"`
	// MaxSubscriptions is total number of subscriptions that may be active on a
	// single websocket connection to this relay. It's possible that
	// authenticated clients with a (paid) relationship to the relay may have
	// higher limits.
	MaxSubscriptions int `json:"max_subscriptions,omitempty"`
	// MaxFilter is maximum number of filter values in each subscription. Must
	// be one or higher.
	MaxFilters int `json:"max_filters,omitempty"`
	// MaxLimit is the relay server will clamp each filter's limit value to this
	// number. This means the client won't be able to get more than this number
	// of events from a single subscription filter. This clamping is typically
	// done silently by the relay, but with this number, you can know that there
	// are additional results if you narrowed your filter's time range or other
	// parameters.
	MaxLimit int `json:"max_limit,omitempty"`
	// MaxSubidLength is the maximum length of subscription id as a string.
	MaxSubidLength int `json:"max_subid_length,omitempty"`
	// MaxEventTags in any event, this is the maximum number of elements in the
	// tags list.
	MaxEventTags int `json:"max_event_tags,omitempty"`
	// MaxContentLength maximum number of characters in the content field of any
	// event. This is a count of unicode characters. After serializing into JSON
	// it may be larger (in bytes), and is still subject to the
	// max_message_length, if defined.
	MaxContentLength int `json:"max_content_length,omitempty"`
	// MinPowDifficulty new events will require at least this difficulty of PoW,
	// based on NIP-13, or they will be rejected by this server.
	MinPowDifficulty int `json:"min_pow_difficulty,omitempty"`
	// AuthRequired means the relay requires NIP-42 authentication to happen
	// before a new connection may perform any other action. Even if set to
	// False, authentication may be required for specific actions.
	AuthRequired bool `json:"auth_required"`
	// PaymentRequired this relay requires payment before a new connection may
	// perform any action.
	PaymentRequired bool `json:"payment_required"`
	// RestrictedWrites this relay requires some kind of condition to be
	// fulfilled in order to accept events (not necessarily, but including
	// payment_required and min_pow_difficulty). This should only be set to true
	// when users are expected to know the relay policy before trying to write
	// to it -- like belonging to a special pubkey-based whitelist or writing
	// only events of a specific niche kind or content. Normal anti-spam
	// heuristics, for example, do not qualify.q
	RestrictedWrites bool        `json:"restricted_writes"`
	Oldest           timestamp.T `json:"created_at_lower_limit,omitempty"`
