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.

LinkedIn Content Best Practices

Professional tone — LinkedIn users expect polished, business-appropriate visuals
Blue dominates — blues convey trust and professionalism; it is the most successful color family on LinkedIn
Light backgrounds perform better in LinkedIn's white feed than dark backgrounds
Single image posts get 2x more engagement than text-only posts
Carousel documents (uploaded as PDFs) get the highest engagement rate of all formats
Consistency builds authority — post with the same visual template regularly

LinkedIn Carousel Strategy

Generate a cohesive set of carousel slides:

from openai import OpenAI

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

slides = [
    "Title slide: bold topic statement area, abstract ascending arrows, navy background",
    "Content slide: clean layout with icon placeholder on left, text area on right, white background with navy accent",
    "Statistics slide: large number display area with subtle chart illustration, light gray background",
    "Summary slide: key takeaways layout with checkmark icons, gradient navy to teal",
    "CTA slide: follow/connect prompt area, matching navy background with subtle pattern"
]

for i, slide_desc in enumerate(slides, 1):
    response = client.chat.completions.create(
        model="eachsense/beta",
        messages=[{
            "role": "user",
            "content": f"LinkedIn carousel slide {i}/5 about leadership principles. {slide_desc}. Professional corporate style, 1080x1080 square format."
        }]
    )
    print(f"Slide {i}: {response.choices[0].message.content}")
