Why choose Sivi design API integration

Why choose Sivi design API integration

Why choose Sivi design API integration

Real vector designs vs raster images

Sivi API delivers editable vector outputs, unlike raster images that pixelate and limit scaling flexibility.

Any dimension vs limited aspect ratios

Sivi API generates designs in custom sizes, avoiding the restrictions of fixed aspect ratio templates.

Automated design generation vs drag-and-drop editing

Sivi API automates design generation programmatically, avoiding manual drag-and-drop steps that slow development workflows.

Brand consistency across designs vs repeated asset setup

Sivi applies brand rules automatically in just a one-time setup, unlike templated tools requiring asset re-uploads for every new design.

Multi-language support vs manual conversion

Sivi API supports 72+ languages, eliminating the need for tedious manual translation and design adaptation.

Template APIs fill in blanks. Image generation APIs produce pixels. The Sivi design API generates structured, layered designs with real text you can actually click and edit.

What makes this different

Layered, editable output

The API returns a structured design file, not a raster image. Every element (text blocks, images, vectors, backgrounds) exists on its own layer with independent coordinates, styles, and properties. You can programmatically access, modify, or remove any element after generation.

Text rendering

The API returns a structured design file, not a raster image. Every element (text blocks, images, vectors, backgrounds) exists on its own layer with independent coordinates, styles, and properties. You can programmatically access, modify, or remove any element after generation.

Layout composition engine

The LDM does not stretch, crop, or scale. It re-composes the entire layout for each target dimension. A 728x90 leaderboard and a 1080x1080 social post get different visual hierarchies, not different zoom levels of the same layout.

Brand system

Attach a brand kit to your API key: hex codes, font families, logo files, spacing rules. The model enforces these as hard constraints on every generation. No per-request configuration needed. No drift across thousands of outputs.

Async generation

POST your request and get a designId back immediately. Poll for completion or register a webhook. The API handles queuing, processing, and delivery. Concurrent requests supported on all plans.

Export pipeline

Each generated design can be exported as JPG, PNG, HTML, or PDF. The export endpoint accepts the designId and returns rendered output in your specified format.

The output is not a screenshot. It is a layered design file where every text block, image, and vector is a separate, editable component.

Sivi API request lifecycle

Phase 1: Request

POST a JSON payload to designs-from-prompt with a natural language prompt, or to designs-from-content with structured data (headline, body, CTA, product URL). Include your brand kit ID, target dimension, language, and numOfVariants.

Phase 2: Generation

The API queues your request and returns a designId immediately. The LDM resolves brand assets, selects layout patterns, and composes a multi-layered design. Typical generation time: under 60 seconds. Use polling or webhook callbacks to detect completion.

Phase 3: Retrieval

Call get-design-variants with your designId. Each variant includes a variantImageUrl (rendered preview), a variantEditLink (anonymous design studio for editing), and layer metadata. Export endpoints return JPG, PNG, HTML, or PDF.

    prompt: "Summer sale banner for urban clothing brand",
    language: "english",
    numOfVariants: 2
  })
});

const result = await response.json();
const designId = result.body.designId;

// Retrieve the generated variants
const variantsRes = await fetch("https://connect.sivi.ai/api/prod/v2/general/get-design-variants", {

    "sivi-api-key": "YOUR_API_KEY",

variants.body.variations.forEach(v => {
  console.log(`Image: ${v.variantImageUrl}`);
  console.log(`Edit: ${v.variantEditLink}`);

Integration options

Platform teams integrate the Sivi API to give their users design superpowers without building design infrastructure from scratch. Here is how different product categories use it.

REST API (headless)

Call designs-from-prompt or designs-from-content, poll get-design-variants for results, and serve the output however you want. No frontend dependency. Best for automated pipelines, batch generation, and server-side processing.

SDK (full design studio)

Import the React component or embed via iframe. The SDK handles generation, editing, and export in your frontend. You control theming, permissions, and user routing.

MCP server (AI agents)

Install the MCP server. Any MCP-compatible client such as Claude, ChatGPT, Cursor, Windsurf calls Sivi as a tool within conversations or automated workflows. No custom integration code.

Hybrid

Use the API for automated, high-volume generation, the SDK for interactive user-facing design, and the MCP server for AI agent workflows. Many integrators use more than one.

Common questions about the design API

How does authentication work?

Every request requires a sivi-api-key header. Create your key at instant.sivi.ai and make your first call. The quickstart guide walks you through generating your first design in under 5 minutes.

Is the Sivi API a template-based system?

No. The API uses the Large Design Model (LDM) and generates original layouts on every call. Send the same prompt twice and get two different, well-composed designs. No template library to build or maintain. Your content and brand kit are the only inputs the model needs.

How is this different from image generation APIs like Nano Banana or Midjourney?

Image generation APIs produce flat raster images with no editable layers and often hallucinate text. The Sivi design API generates structured, multi-layered designs where every text block is real editable text and every element is a separate layer. You get a graphic design API output you can work with, not a frozen image.

How do I handle async generation?

POST your request and receive a designId immediately. Poll the get-design-variants endpoint or register a webhook to be notified on completion. Concurrent requests are supported on all plans.

What user management models does the API support?

The API supports three user management models:

  • User redirection: End-users are redirected to create Sivi accounts directly.

  • API-managed users: Create and manage end-user accounts programmatically with your API key.

  • Fully embedded: Users access design generation without leaving your platform. No Sivi-branded touchpoints.

How is data secured during API interactions?

API keys authenticate every request. All data is encrypted in transit and at rest. Brand assets and generated designs are isolated per account and not used for model training. Enterprise plans include custom data residency options.

How is Sivi API different from Canva API?

Sivi API auto-generates designs from prompts, no templates involved. Canva API provides access to a template-based editor for manual, collaborative design. Sivi is generative infrastructure. Canva is a collaborative editing tool. Full comparison

What enterprise API integration features are available?

Enterprise integration includes:

  • Custom themes and white-labeling options for SDK

  • Flexible deployment options and staging environments

  • Dedicated support and custom feature development

  • Influence on product roadmap

Is there a sandbox for testing?

Yes. The sandbox costs $1 one-time and gives you 20 credits with 7-day validity. Test output quality, integration patterns, and response formats before committing to a paid plan.

Do I own the designs generated through the API?

Yes. All designs generated with your API key are your intellectual property. Sivi does not claim any rights over your generated output or brand assets.

What business owners, marketers, AI enthusiasts, and designers say about Sivi

  • Sivi AI - 5 star rating

    I like how the prompt wizard is created. Generate process is cool. I like the approach when you actually see what is going on, instead of looking at some spinner for X minutes and be not sure if it is still processing or it is freezing. Simple and easy to use Edit mode. This is really cool product.
