OG Image Design

Design compelling Open Graph images for link previews using each::sense — the intelligent AI agent that automatically selects the best model for your request.

Quick Start

Requires an each::labs API key. Get one at eachlabs.ai.

Using curl

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": "Create an OG image for a blog post about machine learning. Dark gradient background from deep navy to dark teal, a stylized neural network visualization glowing in the center, clean and techy, 1200x630 proportions with a large dark area on the left side for article title text overlay."
      }
    ],
    "stream": false
  }'

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 an OG image for a blog post about machine learning. Dark gradient background from deep navy to dark teal, a stylized neural network visualization glowing in the center, clean and techy, 1200x630 proportions with a large dark area on the left side for article title text overlay."
    }]
)

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

With Reference Image

Use brand assets to create consistent OG images:

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 an OG image background that matches this brand style. Same color palette and visual language, 1200x630 proportions, leave generous space for a large title on the left and a small logo area in the bottom right corner."},
              {"type": "image_url", "image_url": {"url": "https://example.com/brand-style.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.

Where OG Images Appear

Platform	Display	Notes
Twitter/X	Summary large image card	Crops to 2:1 on feed
Facebook	Link preview	Full 1200x630 display
LinkedIn	Article/link share	Prominent in feed
Slack	URL unfurl	Inline preview
Discord	Embed card	Sidebar preview
iMessage	Link preview bubble	Compact view

Prompt Engineering Tips

Keywords That Work

OG image, link preview graphic, 1200x630 proportions, bold visual,
high contrast, clear focal point, dark background with text area,
branded and professional, eye-catching at small sizes, social share image

Keywords to Avoid

detailed small elements — OG images are often viewed at 300px wide
centered text — different platforms crop differently
important content at edges — safe zone is the inner 80%
light gray backgrounds — low contrast on white platform UIs

Prompt Structure

OG image for [content type], [visual elements], [background], [color palette], 1200x630 proportions, [text area placement]

Examples

Developer Blog Post

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": "Design an OG image for a developer blog about API design. Dark charcoal background, stylized code brackets and curly braces floating in teal and green, subtle grid pattern, developer tool aesthetic, 1200x630, left half reserved for title text."
      }
    ],
    "stream": false
  }'

Product Launch Page

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": "Create an OG image for a SaaS product launch. Gradient from deep indigo to violet, abstract dashboard mockup fading in from the right edge, glowing accent highlights, premium tech feel, 1200x630, center-left area clear for product name."
      }
    ],
    "stream": false
  }'

Podcast Episode Share

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": "Design an OG image for a podcast episode share. Warm dark background with a vintage microphone illustration on the right side, abstract sound waves radiating outward in gold and amber tones, cozy and professional podcast aesthetic, 1200x630, left side for episode title."
      }
    ],
    "stream": false
  }'

OG Image Best Practices

• 1200 x 630 pixels is the universal recommended size
• Keep critical content in the center 80% — platforms crop edges differently
• Dark backgrounds with light text areas perform best on most platforms
• Bold and simple — the image is often displayed at thumbnail size
• Consistent template — use the same layout across all pages for brand recognition
• Test across platforms — check how your image looks on Twitter, Facebook, and Slack

Automated OG Image Pipeline

For blogs and content sites, batch-generate OG images:

from openai import OpenAI

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

topics = [
    "API authentication best practices",
    "Database scaling strategies",
    "CI/CD pipeline optimization"
]

for topic in topics:
    response = client.chat.completions.create(
        model="eachsense/beta",
        messages=[{
            "role": "user",
            "content": f"Create an OG image background for a technical blog post about {topic}. Dark navy gradient, subtle tech-themed visual element on the right, clean left side for title overlay, professional developer aesthetic, 1200x630 proportions."
        }]
    )
    print(f"OG image for '{topic}': {response.choices[0].message.content}")

Workflow

# Step 1: Create the base OG template
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \

      }
    ],
    "stream": false
  }'

# Step 2: Create a variation for a specific post
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
