API Reference Open Graph image template

An API reference card: an 'API Reference' eyebrow, a METHOD badge with a mono endpoint path, a title and description, and a rounded code panel showing a faux JSON response.

It's built for the standard 1200×630 (1.91:1) share card and exports at 2× (2400×1260) for high-DPI screens. Customize the text, colors, fonts, and logo in your browser, then download a PNG — free, no signup, nothing uploaded.

3 ready-made presets

Each preset is a one-click starting look for the API Reference template — a different color and type combination you can still fully edit.

What you can edit

The API Reference template has 6 editable content fields. Recommended lengths keep your copy inside the safe area so nothing clips when the card is cropped.

Field	Type	Max length	Example
Eyebrow	Single line	18 chars	API Reference
HTTP method	Single line	8 chars	GET
Endpoint path	Single line	40 chars	/v1/images/generate
Title*	Multi-line	40 chars	Generate an Image
Description	Single line	80 chars	Create a new render from a template id and slot values.
Response (JSON)	Multi-line	160 chars	{ "id": "img_8f2a", "status": "ready" }

* required field. Tip: keep your “Title” short and punchy — the shorter the copy, the larger and more legible it renders in the feed.

Styling you control

Beyond the words, the API Reference template lets you tune:

Background color & style
Gradient fills
Grid & pattern overlays
Fonts, size & alignment
Logo placement
Platform size switching
Film-grain / noise
Vignette

When to use it

The API Reference template lives in the developer collection — developer-native cards that speak to engineers. Reach for it specifically when one of these fits:

A CLI tool or library
An API or docs page
A changelog or release
A repo, PR, or build-status card
