What is CurlShot?
CurlShot gives your app, your scripts and your AI agents a clear look at any web page.
ONE REQUEST
Send a page address, HTML or Markdown to one endpoint and get back an image (PNG, JPEG, WebP), a PDF, or a scrolling video (MP4, WebM, GIF). No SDK: anything that can fetch a URL already works, and the docs have examples for cURL, Node.js, Python, PHP, Go and Ruby.

WHO IT IS FOR
Developers adding previews or PDFs to a product, teams automating reports and checks in n8n or their own scripts, and builders giving AI agents a way to look at web pages.
PRICES
A free plan with 100 screenshots a month and no card. Paid plans have a fixed monthly price: $19, $79 or $249. Yearly billing gets 2 months free. 14-day money-back guarantee.

What problem it solves
Running headless browsers in production is fragile: cookie banners, lazy images, timeouts, memory and queues. Developers who need screenshots, PDFs or page videos in their apps, pipelines or AI agents get them from one HTTP request instead.
Alternatives & competitors
An alternative to running Puppeteer or Playwright yourself, and to other screenshot APIs.
What is Optio?
Optio is a developer API that returns decisions you can build on. Send a question and a set of options and get back a choice, a score, or a yes/no answer together with calibrated probabilities, so your application knows not just what the model picked but how confident it is. The API is a drop-in /v1/systemone endpoint that you can call from any language with a simple HTTP request. A free playground on the website lets you try the decision model in the browser before writing any code. There is no waitlist: sign up, get credits and start calling the API right away, then pay as you go with credits when you scale. Optio is built for developers, startups and product teams who want to add decision-making, ranking, triage or approval logic to their apps without training and hosting their own models.
What problem it solves
Developers who need reliable yes/no, choice and scoring decisions with probabilities they can trust, without building their own model.
