ApiFlash Screenshot API

About ApiFlash Screenshot API

ApiFlash is a website screenshot API that uses a headless Chrome browser running on AWS Lambda to capture pixel-perfect screenshots of any URL. It is designed for developers and businesses that need to automate screenshot generation at scale, such as for website monitoring, archiving, visual regression testing, or content previews. The API is accessed via a simple HTTPS endpoint (GET or POST to https://api.apiflash.com/v1/urltoimage). Requests are authenticated with an API access key passed as a query parameter. By default the response is the raw image binary with appropriate Content-Type headers; setting response_type=json returns a JSON document with a link to the captured image instead. ApiFlash includes automatic detection of fully loaded pages before capturing, which avoids blank or partially rendered screenshots. Developers can control viewport width and height, enable full-page capture (scrolling the entire document), emulate mobile devices, inject custom CSS or JavaScript, pass custom HTTP headers and cookies (enabling screenshots of authenticated pages), set the output image format, and specify an IP geolocation to simulate regional content. The service is built on AWS Lambda, which gives it horizontal scalability: it handles large bursts without queuing delays. ApiFlash claims average response times under one second for most requests. The free tier provides 100 screenshots per month with no credit card required. Paid plans start at roughly $7/month for 100 screenshots, $16/month for 1,000 screenshots, and $49/month for 10,000 screenshots, with higher-volume enterprise tiers available.
