Introduction

PreviewAPI turns URLs into hosted screenshot images through a small JSON API. You submit a capture job, poll its status, and read the final image URL. There are no browsers to run, no queues to manage, and no image storage to provision.

Endpoints

Job lifecycle

Every job moves through a fixed set of states. Poll the status endpoint until it reaches a terminal state.

A completed job consumes one credit and returns a hosted image URL. A failed job is refunded automatically.
