# Images

> Images endpoints

## Overview

Images endpoints

### Available Operations

* [Generate](#generate) - Generate an image
* [ListModels](#listmodels) - List image generation models
* [ListModelEndpoints](#listmodelendpoints) - List endpoints for an image model

## Generate

Generates an image from a text prompt via the image generation router

### Example Usage

```go theme={null}
package main

import(
	"context"
	"os"
	openrouter "github.com/OpenRouterTeam/go-sdk"
	"github.com/OpenRouterTeam/go-sdk/models/components"
	"log"
)

func main() {
    ctx := context.Background()

    s := openrouter.New(
        openrouter.WithSecurity(os.Getenv("OPENROUTER_API_KEY")),
    )

    res, err := s.Images.Generate(ctx, components.ImageGenerationRequest{
        Model: "bytedance-seed/seedream-4.5",
        Prompt: "a red panda astronaut floating in space, studio lighting",
    })
    if err != nil {
        log.Fatal(err)
    }
    if res != nil {
        defer res.ImageStreamingResponse.Close()

        for res.ImageStreamingResponse.Next() {
            event := res.ImageStreamingResponse.Value()
            log.Print(event)
            // Handle the event
	      }
    }
}

## ListModels

Lists every image generation model with its top-level supported-parameter superset and a URL to its full per-endpoint records.

    ctx := context.Background()

    s := openrouter.New(
        openrouter.WithSecurity(os.Getenv("OPENROUTER_API_KEY")),
    )

    res, err := s.Images.ListModels(ctx)
    if err != nil {
