Quick Start

Get your first image generated in under 5 minutes.

1. Get an API Key

Sign up at the Weyl platform and create an API key.

Terminal window
export WEYL_API_KEY=wyl_sk_prod_1234567890abcdef

2. Generate Your First Image

Terminal window
curl -X POST "https://sync.render.weyl.ai/image/flux/schnell/t2i?format=1024" \
  -H "Authorization: Bearer $WEYL_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt":"cyberpunk street at night, neon rain"}' \
  -o output.webp

The response body contains the image bytes. The Content-Location header points to the permanent CDN URL.

3. Try Different Models

FLUX.2 Dev (32B, highest quality)

Terminal window
curl -X POST "https://sync.render.weyl.ai/image/flux/dev2/t2i?format=1024" \
  -H "Authorization: Bearer $WEYL_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt":"portrait of a woman, rembrandt lighting"}' \
  -o portrait.webp

Z-Image Turbo (sub-second generation)

Terminal window
curl -X POST "https://sync.render.weyl.ai/image/zimage/turbo/t2i?format=1024" \
  -H "Authorization: Bearer $WEYL_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt":"mountain landscape, golden hour"}' \
  -o landscape.webp

4. Use with Python

import requests
import os


def generate_image(prompt: str) -> bytes:
    url = "https://sync.render.weyl.ai/image/flux/schnell/t2i?format=1024"


    headers = {
        "Authorization": f"Bearer {os.environ['WEYL_API_KEY']}",
        "Content-Type": "application/json"
    }


    payload = {"prompt": prompt}


    resp = requests.post(url, headers=headers, json=payload)
    resp.raise_for_status()


    # Get permanent CDN URL
    cdn_url = resp.headers.get('Content-Location')
    print(f"Permanent URL: {cdn_url}")


    return resp.content


# Generate
image_bytes = generate_image("neon city at night")


with open("output.webp", "wb") as f:
    f.write(image_bytes)
