Opengraph Io

Data & APIs

Extract web data, capture screenshots, scrape content, and generate AI images via OpenGraph.io. Use when working with URLs (unfurling, previews, metadata), capturing webpage screenshots, scraping HTML content, asking questions about webpages, or generating images (diagrams, icons, social cards, QR codes). Triggers: 'get the OG tags', 'screenshot this page', 'scrape this URL', 'generate a diagram', 'create a social card', 'what does this page say about'.

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

Clawdbot Usage (REST API)

Use curl with the OPENGRAPH_APP_ID environment variable. Base URL: https://opengraph.io/api/1.1/

Extract OpenGraph Data (Site/Unfurl)

# Get OG tags from a URL
curl -s "https://opengraph.io/api/1.1/site/$(echo -n 'https://example.com' | jq -sRr @uri)?app_id=${OPENGRAPH_APP_ID}"

Response includes hybridGraph.title, hybridGraph.description, hybridGraph.image, etc.

Screenshot a Webpage

# Capture screenshot (dimensions: sm, md, lg, xl)
curl -s "https://opengraph.io/api/1.1/screenshot/$(echo -n 'https://example.com' | jq -sRr @uri)?app_id=${OPENGRAPH_APP_ID}&dimensions=lg"

Response: { "screenshotUrl": "https://..." }

Scrape HTML Content

# Fetch rendered HTML (with optional proxy)
curl -s "https://opengraph.io/api/1.1/scrape/$(echo -n 'https://example.com' | jq -sRr @uri)?app_id=${OPENGRAPH_APP_ID}&use_proxy=true"

Extract Specific Elements

# Pull h1, h2, p tags
curl -s "https://opengraph.io/api/1.1/extract/$(echo -n 'https://example.com' | jq -sRr @uri)?app_id=${OPENGRAPH_APP_ID}&html_elements=h1,h2,p"

Query (Ask AI About a Page)

  -H "Content-Type: application/json" \
  -d '{"name": "my-session"}')
SESSION_ID=$(echo $SESSION | jq -r '.sessionId')

Step 2: Generate an Image

curl -s -X POST "https://opengraph.io/image-agent/sessions/${SESSION_ID}/generate?app_id=${OPENGRAPH_APP_ID}" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A beautiful QR code linking to https://example.com with modern gradient design",

MCP Integration (for Claude Desktop, Cursor, etc.)

For AI clients that support MCP, use the MCP server:

# Interactive installer
npx opengraph-io-mcp --client cursor --app-id YOUR_APP_ID

# 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.
