How this service works
Render a Open Graph link preview card (1200x630) as PNG with exact typography. The text in the output is exactly the text supplied — no garbled lettering, unlike diffusion models. Responds with the raw 1200x630 PNG bytes, not JSON.
Output
Raw PNG image bytes (not JSON) for a 1200x630 pixel Open Graph card with exactly the supplied headline, kicker, CTA, bullets, and color scheme rendered with crisp vector-quality typography — ready to serve as an og:image meta tag asset.
Example use cases
Blog post social sharing card
“Create an OG preview image for my new article with the headline 'How to Build Profitable AI Agents\nIn 30 Days', kicker 'Tutorial', CTA 'Start Now', bullets ['Step-by-step guide', 'No prior ML needed', 'Free starter template'], white background, black ink, and a blue accent (#2563eb).”
Product launch link preview
“Make a 1200x630 Open Graph card for our product launch — headline 'Introducing Spark\nThe AI Copilot for Finance', kicker 'Launch Day', CTA 'Try Free', background color #1e293b, white ink, and orange accent (#f97316), with bullets ['Real-time portfolio insights', 'One-click rebalancing', 'Bank-grade security'].”
Newsletter issue preview card
“Render an OG image for this week's newsletter issue: headline 'Weekly Roundup\n5 Things You Missed', kicker 'Issue #42', no CTA, bullets ['AI funding hits record', 'Open source wins', 'Remote work rebounds'], light gray background (#f8fafc), dark ink (#111827), teal accent (#0d9488).”
Technical details
Endpoint
POSThttps://x402render-u5vwpxpyua-uc.a.run.app/og-imageWhen to prefer
Choose this endpoint when you need programmatically generated Open Graph cards with guaranteed typographic accuracy — especially when diffusion-model image generators would garble text. Ideal for automating social preview images for blogs, newsletters, product pages, or any URL that needs a polished og:image without a design tool. Prefer this over AI image generators when exact text rendering is a hard requirement.
Side effects
- Missing or empty headline may produce a blank or malformed card
- Invalid hex color strings may cause a rendering error or fallback to defaults
- Very long headline text may overflow the card layout
- Network timeout on the Cloud Run cold-start if the container hasn't warmed up
- Payment failure (x402 protocol) if USDC balance is insufficient for the $0.03 fee
