Using Python (OpenAI SDK)

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_EACHLABS_API_KEY",
    base_url="https://eachsense-agent.core.eachlabs.run/v1"
)

response = client.chat.completions.create(
    model="eachsense/beta",
    messages=[{
        "role": "user",
        "content": "Create a square social media post graphic for a summer sale promotion. Vibrant gradient background in coral and gold, bold geometric shapes, clean modern layout with space for overlay text, fashion brand aesthetic."
    }]
)

print(response.choices[0].message.content)

With Reference Image

Use a brand reference or mood board to maintain visual consistency:

curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "messages": [
      {
        "role": "user",
        "content": [
              {"type": "text", "text": "Create a social media post in the same visual style as this brand reference. Announce a new product launch, keep the color palette and layout consistent, modern and clean."},
              {"type": "image_url", "image_url": {"url": "https://example.com/brand-reference.jpg"}}
            ]
          }
    ],
    "stream": false
  }'

Images are sent inside messages using the OpenAI multimodal content format. Maximum 4 images per request.

Streaming

Set "stream": true for real-time SSE responses, or "stream": false for complete result in a single response. Streaming is useful for showing progress in UIs; non-streaming is simpler for scripts and automation.

Content Strategy Tips

Consistency beats perfection — use the same color palette and style across posts
Leave text space — always reserve 30-40% of the image for text overlay
Mobile first — design for small screens, keep elements large and clear
Brand colors — mention specific hex codes or color names in your prompts for consistency
Batch creation — generate multiple variations in one session for A/B testing
