Quick Decision Guide

"I need data from a URL"

Need	Endpoint
Meta tags / link preview data	GET /site/{url}
Raw HTML content	GET /scrape/{url} (add use_proxy=true if geo-blocked)
Specific elements (h1, h2, p)	GET /extract/{url}?html_elements=h1,h2,p
AI answer about the page	POST /query/{url} ⚠️ paid
Visual screenshot	GET /screenshot/{url}

"I need to generate an image"

Need	Settings
Technical diagram	kind: "diagram" — use diagramCode + diagramFormat for control
App icon/logo	kind: "icon" — set transparent: true
Social card (OG/Twitter)	kind: "social-card" — use aspectRatio: "og-image"
Basic QR code	kind: "qr-code"
Premium QR marketing card	kind: "illustration" — describe full design in prompt
General illustration	kind: "illustration"

QR Code: Basic vs Premium

Basic (kind: "qr-code"): Just the functional QR code.

Premium (kind: "illustration"): Full marketing asset with QR embedded in designed composition (gradients, 3D elements, CTAs, device mockups). Example prompt:

"Premium marketing card with QR code for https://myapp.com, cosmic purple gradient 
with floating 3D spheres, glowing accents, 'SCAN TO DOWNLOAD' call-to-action"

Diagram Tips

• Use diagramCode + diagramFormat for reliable syntax (bypasses AI generation)
• Use outputStyle: "standard" for structure-critical diagrams (premium may alter layout)
• ❌ Don't mix syntax with description: "graph LR A-->B make it pretty" will fail

# Or configure manually:
{
  "mcpServers": {
    "opengraph": {
      "command": "npx",
      "args": ["-y", "opengraph-io-mcp"],
      "env": {
        "OPENGRAPH_APP_ID": "YOUR_APP_ID"
      }
    }
  }
}

See references/mcp-clients.md for client-specific setup.
