ideogram-hello-world（表意文字你好世界）

Ideogram Hello World

Overview

Generate your first AI image with Ideogram. Demonstrates the legacy /generate endpoint (JSON body) and the V3 /v1/ideogram-v3/generate endpoint (multipart form). Both return temporary image URLs that must be downloaded promptly.

Prerequisites

• Completed ideogram-install-auth setup
• IDEOGRAM_API_KEY environment variable set
• Node.js 18+ or Python 3.10+

Instructions

Step 1: Quick Test with curl

set -euo pipefail
# Legacy endpoint (V_2 model, JSON body)
curl -s -X POST https://api.ideogram.ai/generate \
  -H "Api-Key: $IDEOGRAM_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image_request": {
      "prompt": "A cheerful golden retriever wearing sunglasses on a beach, with text saying \"Hello Ideogram!\"",
      "model": "V_2",
      "style_type": "REALISTIC",
      "aspect_ratio": "ASPECT_16_9",
      "magic_prompt_option": "AUTO"
    }
  }' | jq '.data[0] | {url, seed, resolution, is_image_safe}'

Step 2: TypeScript -- Generate and Download

// hello-ideogram.ts
import { writeFileSync } from "fs";

async function helloIdeogram() {
  // Generate an image with embedded text (Ideogram's specialty)
  const response = await fetch("https://api.ideogram.ai/generate", {
    method: "POST",
    headers: {
      "Api-Key": process.env.IDEOGRAM_API_KEY!,
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      image_request: {
        prompt: 'Modern poster design with bold text "HELLO WORLD" in neon gradient, dark background, clean typography',
        model: "V_2",
        style_type: "DESIGN",
        aspect_ratio: "ASPECT_1_1",
        magic_prompt_option: "AUTO",
        num_images: 1,
      },
    }),
  });

  if (!response.ok) {
    throw new Error(`Generation failed: ${response.status} ${await response.text()}`);
  }

  const result = await response.json();
  const image = result.data[0];

  console.log("Generated image:");
  console.log("  URL:", image.url);
  console.log("  Seed:", image.seed);
  console.log("  Resolution:", image.resolution);
  console.log("  Style:", image.style_type);
  console.log("  Safe:", image.is_image_safe);

  // Download immediately -- URLs expire after ~1 hour
  const imgResponse = await fetch(image.url);
  const buffer = Buffer.from(await imgResponse.arrayBuffer());
  writeFileSync("hello-ideogram.png", buffer);
  console.log("Saved to hello-ideogram.png");
}

helloIdeogram().catch(console.error);

Step 3: Python -- Generate and Download

# hello_ideogram.py
import os, requests

response = requests.post(
    "https://api.ideogram.ai/generate",
    headers={
        "Api-Key": os.environ["IDEOGRAM_API_KEY"],
        "Content-Type": "application/json",
    },
    json={
        "image_request": {
            "prompt": 'Modern poster design with bold text "HELLO WORLD" in neon gradient, dark background',
            "model": "V_2",
            "style_type": "DESIGN",
            "aspect_ratio": "ASPECT_1_1",
            "magic_prompt_option": "AUTO",
        }
    },
)
response.raise_for_status()

image = response.json()["data"][0]
print(f"URL: {image['url']}")
print(f"Seed: {image['seed']}")

# Download the image (URLs expire)
img_data = requests.get(image["url"]).content
with open("hello-ideogram.png", "wb") as f:
    f.write(img_data)
print("Saved to hello-ideogram.png")
