# APIs that render things

> Screenshots, social images, link previews: small APIs that turn a URL or a template into a picture make steady, usage-based revenue.

Developers keep needing the same visual chores: a screenshot of a page, an Open Graph image for every post, a preview card for a link. Each is annoying to build and maintain with a headless browser, so people happily pay per render.

## Why it works

- **Clear unit of value.** One render, one credit. Usage-based pricing maps directly to the customer's growth.
- **Infrastructure is the moat.** Running browsers at scale, blocking cookie banners and handling odd sites is the hard part that buyers don't want to own.
- **No-code reach.** Zapier and Make integrations open the same API to marketers.

## Watch out for

Margins depend on compute costs, and a few large customers can dominate revenue. The products below balance that with self-serve plans for many small users.
