Social images from one URL — 30 templates, edge-rendered

OpenGraphAPI is a developer API that turns one GET request into a ready-to-embed 1200×630 image: OG cards, certificates, product shots, podcast episode cards. 30 templates, 10 themes, WASM rendering on Cloudflare's edge. Free tier: 300 images/day with a small watermark, no credit card.
Hey PH! 👋 I'm Lei, a solo dev from China . I built OpenGraphAPI with AI pair-programming and shipped the whole thing in 3 days — this is my first launch here.
The pitch: one URL = one finished social image.
If your blog posts, products or course certificates never got their OG images because "someone has to design them" — now nobody has to:
``
Every page, every product, every issue gets its own 1200×630 PNG automatically. 30 templates (OG cards, certificates, product shots, podcast covers...), 10 themes.
Under the hood: no headless-browser farm, no GPU. satori + resvg compiled to WASM, rendered on Cloudflare's edge in ~50ms — that's why the free tier can exist: 300 images/day, no credit card.

I'd love brutal feedback:
• Which template looks worst? (I'll fix it this week)
• What would you automate with this first?
• What's the one feature that would make you pay?
This account ships fixes weekly. Roast the templates, break the API — I read and answer every comment. 🚀
