Browser automation

Some data lives behind interaction — a button click, a form, a multi-step flow. The String Web Access API gives you two ways to handle it.

Lightweight: browser actions

For short, scripted sequences (and optional screenshots), pass an actions array to /fetch. The API runs them in a managed browser and returns the final HTML and any screenshot.

{
  "url": "https://example.com",
  "actions": [
    { "type": "click", "selector": "#accept-cookies" },
    { "type": "write", "text": "hello" },
    { "type": "press", "key": "Enter" },
    { "type": "screenshot" }
  ]
}

Full control: CDP browser

For open-ended automation — logins, long flows, anything dynamic — connect Puppeteer or Playwright to the CDP browser and drive the page directly.

Choosing between them

Both apply access control to every navigation.
