Documentation

Overview

Package midjourney implements engine.Engine for MidJourney image generation via third-party proxy APIs (e.g. GoAPI at api.goapi.ai).

Image generation is async: POST /mj/v2/imagine creates a task, then POST /mj/v2/fetch polls for completion. Auth: X-API-Key: {key}, env MIDJOURNEY_API_KEY.

Functions

func ConfigSchema

func ConfigSchema() []engine.ConfigField

ConfigSchema returns the configuration fields required by the MidJourney engine.

func DefaultProvider

func DefaultProvider() engine.Provider

DefaultProvider returns preset engine configurations for midjourney.

func ModelInfos

func ModelInfos() []engine.ModelInfo

ModelInfos returns i18n metadata for all MidJourney models.

func ModelsByCapability

func ModelsByCapability() map[string][]string

ModelsByCapability returns all known MidJourney models grouped by capability.

Types

type Config

type Config struct {
	APIKey            string
	BaseURL           string
	ProcessMode       string // "fast" or "relax"
	HTTPClient        *http.Client
	WaitForCompletion bool
	PollInterval      time.Duration
	OnProgress        epoll.OnProgress
}

Config configures the MidJourney proxy engine.

type Engine

type Engine struct {
	// contains filtered or unexported fields
}

Engine implements engine.Engine for MidJourney via a proxy API.

func New

func New(cfg Config) *Engine

New creates a MidJourney engine instance.

func (*Engine) Capabilities

func (e *Engine) Capabilities() engine.Capability

Capabilities implements engine.Describer.

func (*Engine) Execute

func (e *Engine) Execute(ctx context.Context, g workflow.Graph) (engine.Result, error)

Execute generates an image via the MidJourney proxy API.

func (*Engine) Resume

func (e *Engine) Resume(ctx context.Context, remoteID string) (engine.Result, error)

Resume implements engine.Resumer — resumes polling a previously submitted task.
