How this service works
Render a X / Twitter card (1200x675) 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 1200x675 PNG bytes, not JSON.
Output
Raw PNG image bytes (1200x675 pixels) representing the rendered Twitter/X card. The response is not JSON — it is the binary PNG file directly, ready to save or upload. Text is rendered with exact, lossless typography matching the input strings, with no AI-induced character distortion.
Example use cases
Blog post Twitter link preview
“Create a 1200x675 Twitter card PNG for my new blog post — headline 'The Future of Async APIs\nIs Already Here', kicker 'Dev Blog', bullets 'x402 protocol', 'Pay-per-call pricing', 'Zero setup', CTA 'Read now', dark gray background, white text, blue accent.”
Product launch announcement card
“Render a Twitter card for our product launch: headline 'Introducing Orbit 2.0\nYour AI Copilot', background color #0f172a, ink #f8fafc, accent #6366f1, kicker 'Product News', bullets 'Faster than ever', 'Multimodal support', 'Free tier available', and CTA 'Try it free'.”

Technical details
Endpoint
POSThttps://x402render-u5vwpxpyua-uc.a.run.app/twitter-card?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pixel-perfect, guaranteed-legible text on a 1200x675 social card — especially when diffusion-model image generators would garble or hallucinate the lettering. It is the right choice for programmatic generation of Twitter/X link preview cards, OG images, or announcement graphics where exact headline and bullet text must be reproduced faithfully. Prefer it over general-purpose AI image generators any time typographic accuracy is non-negotiable.
Side effects
- Missing or empty headline may produce a blank or malformed card
- Invalid hex color strings for bg, ink, or accent may cause rendering errors or fallback to defaults
- Extremely long headline text may overflow the card boundaries
- Network timeout on the cloud run endpoint if under cold-start latency
- Non-UTF-8 characters in text fields may not render as expected
- Bullets array with too many items may clip off the card edge
