Recraft V4 has become one of the most talked-about image generation models among designers and developers. Its ability to generate images with accurate text rendering, consistent brand styles, and professional-quality outputs sets it apart from other models.

In this tutorial, you'll learn how to access the Recraft V4 API through NexaAPI — the unified API platform that gives you access to 56+ AI models at the best prices.

What Makes Recraft V4 Special?

Recraft V4 stands out for:

  • Exceptional text rendering: Accurate text in images (logos, banners, signs)
  • Style consistency: Maintain brand identity across multiple generations
  • Vector-style outputs: Clean, professional graphics

It's particularly popular for:

  • Marketing materials and social media graphics
  • Logo and brand asset generation
  • Technical diagrams and infographics
  • Product mockups

Quick Start: Python 

# Install: pip install nexaapi
from nexaapi import NexaAPI

client = NexaAPI(api_key='YOUR_API_KEY')

# Generate with Recraft V4
result = client.images.generate(
    model='recraft-ai/recraft-v3',  # check nexa-api.com for latest Recraft V4 slug
    prompt='A minimalist tech company logo with the text "NOVA" in clean sans-serif font, blue gradient, white background',
    width=1024,
    height=1024
)

print(result.url)  # Direct URL to generated image
Enter fullscreen mode Exit fullscreen mode

Batch Generation Example 

from nexaapi import NexaAPI
import asyncio

client = NexaAPI(api_key='YOUR_API_KEY')

# Generate multiple social media assets
prompts = [
    'Instagram post: Product launch announcement for wireless headphones, modern design, purple gradient',
    'Twitter banner: Tech startup banner with circuit board pattern, dark theme, neon accents',
    'LinkedIn cover: Professional consulting firm, clean corporate design, navy blue'
]

for prompt in prompts:
    result = client.images.generate(
        model='recraft-ai/recraft-v3',
        prompt=prompt,
        width=1024,
        height=1024
    )
    print(f'Generated: {result.url}')
    # Cost: $0.003 per image
Enter fullscreen mode Exit fullscreen mode

Quick Start: JavaScript 

// Install: npm install nexaapi
import NexaAPI from 'nexaapi';

const client = new NexaAPI({ apiKey: 'YOUR_API_KEY' });

async function generateWithRecraft() {
  const result = await client.images.generate({
    model: 'recraft-ai/recraft-v3', // check nexa-api.com for latest Recraft V4 slug
    prompt: 'A minimalist tech company logo with the text "NOVA" in clean sans-serif font, blue gradient, white background',
    width: 1024,
    height: 1024
  });

  console.log('Image URL:', result.url);
}

generateWithRecraft();
Enter fullscreen mode Exit fullscreen mode

React Integration Example 

import NexaAPI from 'nexaapi';
import { useState } from 'react';

const client = new NexaAPI({ apiKey: process.env.NEXT_PUBLIC_NEXA_API_KEY });

export function ImageGenerator() {
  const [imageUrl, setImageUrl] = useState(null);
  const [loading, setLoading] = useState(false);

  async function generate(prompt) {
    setLoading(true);
    try {
      const result = await client.images.generate({
        model: 'recraft-ai/recraft-v3',
        prompt,
        width: 1024,
        height: 1024
      });
      setImageUrl(result.url);
    } finally {
      setLoading(false);
    }
  }

  return (
    <div>
      <button onClick={() => generate('Modern logo design')} disabled={loading}>
        {loading ? 'Generating...' : 'Generate'}
      </button>
      {imageUrl && <img src={imageUrl} alt="Generated" />}
    </div>
  );
}

Prompt Tips for Recraft V4

Recraft V4 responds especially well to:

  1. Text in images: Specify font style — "clean sans-serif", "bold serif", "handwritten"
  2. Style keywords: "minimalist", "flat design", "isometric", "photorealistic"
  3. Color specifications: Use specific colors — "#3B82F6 blue", "navy and gold", "monochrome"
  4. Use case context: Tell it what it's for — "for a mobile app icon", "for a LinkedIn banner"

High-performing prompts:

  • "App icon for a meditation app: zen circle, gradient from deep blue to purple, minimal, 1024x1024"
  • "Business card design: law firm 'Smith & Associates', gold on dark navy, classic serif font"
  • "Infographic header: 'AI Trends 2026', futuristic style, data visualization elements"
