Frequently asked questions
How many screenshots can I take for free?
Every free key gets 20 renders per day, plus a 50 renders per day limit per IP. No credit card is required while the probe runs.
What image formats does Shot support?
PNG, JPEG and WebP. JPEG and WebP take a quality setting from 10 to 100. You can capture the full page or a single element with a CSS selector.
Are repeat screenshots cached?
Yes. The same URL and parameters are served from a 1-hour cache, and cached renders do not consume your daily quota.
Is there a rate limit?
Yes: 5 requests per minute per key, 20 renders per day per key, and 50 renders per day per IP. Over the limit you get a 429 or 402 response with a Retry-After header.
Can Shot screenshot private or internal URLs?
No. Private IPs, localhost, cloud metadata endpoints and redirect tricks are blocked. Only public http/https URLs are rendered.
