API

One Sogni API key reaches every model on the Supernet — call Openjourney with the exact model id for the variant you want.

import { SogniClient } from '@sogni-ai/sogni-client';

const client = await SogniClient.createInstance({
  appId: crypto.randomUUID(),
  apiKey: process.env.SOGNI_API_KEY,
  network: 'fast',
});

const project = await client.projects.create({
  type: 'image',
  modelId: 'coreml-openjourney-v4-palettized',
  positivePrompt: 'a slothicorn surfing a wave of liquid paint, studio lighting',
  numberOfMedia: 1,
});

const [url] = await project.waitForCompletion();
console.log(url); // result link — download within 24h
# coreml-openjourney-v4-palettized is addressable by id via the JavaScript SDK (see the JavaScript tab).
# The REST workflow API routes this family through its flagship alias instead:

curl https://api.sogni.ai/v1/creative-agent/workflows \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $SOGNI_API_KEY" \
  -d '{
    "input": {
      "title": "First render",
      "steps": [{
        "id": "step1",
        "toolName": "generate_image",
        "arguments": { "prompt": "a slothicorn surfing a wave of liquid paint, studio lighting" }
      }]
    },
    "confirm_cost": true
  }'

Example uses coreml-openjourney-v4-palettized. Use any exact model id from the Variants table above. Full reference at docs.sogni.ai.
