End-to-end slide generation from a topic or document. This is the recommended tool for most use cases. When you call this tool, Poesius automatically performs three steps:
  1. Generates the presentation narrative - Creates a McKinsey-style story, summarizing key findings and revealing insights from your content
  2. Retrieves layout details - Gets template specifications including colors, layout zones, and design elements (defined visually in the web app at https://app.poesius.com)
  3. Creates slides - Combines the narrative with template specs to produce professional PPTX files

Template Required Response

If template_id is not provided and there’s no default template, you’ll receive:

Python Example

import requests
import base64

API_KEY = "pk_your_api_key_here"
BASE_URL = "https://poe.poesius.com/api/v1/mcp"

def read_document(file_path):
    with open(file_path, 'rb') as f:
        return base64.b64encode(f.read()).decode('utf-8')

def generate_slides(topic=None, instructions, template_id, num_slides, document_path=None):
    arguments = {
        "instructions": instructions,
        "template_id": template_id,
        "num_slides": num_slides
    }
    
    if topic:
        arguments["topic"] = topic
    
    if document_path:
        arguments["document_base64"] = read_document(document_path)
    
    response = requests.post(
        f"{BASE_URL}/messages",
        headers={
            "X-API-Key": API_KEY,
            "Content-Type": "application/json"
        },
        json={
            "method": "tools/call",
            "params": {
                "name": "generate_slides",
                "arguments": arguments
            }
        }
    )
    return response.json()

# Generate from topic
result = generate_slides(
    topic="Quarterly Business Review",
    instructions="Create a comprehensive presentation with 15 slides",
    template_id="123e4567-e89b-12d3-a456-426614174000",
    num_slides=15
)

print(f"Generated {result['result']['total_slides']} slides")
print(f"Download URL: {result['result']['download_url']}")

​
Best Practices

  • Use Templates: Always specify a template_id for consistent branding
  • Clear Instructions: Be specific about what you want in the presentation
  • Slide Count: Specify a target number based on your needs
  • Document Encoding: Ensure documents are properly base64-encoded
