Most screenshot APIs charge per screenshot. That math gets scary fast if you're generating previews for thousands of URLs. denkbot.dog has a free public endpoint and a generous authenticated tier. The dog takes photos. You don't watch the meter.
Startups building link preview features, indie developers adding visual URL cards, small teams that need screenshots without per-screenshot billing.
<!-- Free public endpoint — no auth needed -->
