Console

Capture the JavaScript console output a page produces as it loads — errors, warnings and uncaught exceptions. Useful for monitoring third-party scripts, catching regressions and health-checking your own pages.

It uses no AI, and costs 1 credit per call. See Credits.

curl -X POST https://urlpipe.dev/console \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com"}'

const res = await fetch("https://urlpipe.dev/console", {

  headers: {
    "Authorization": "Bearer YOUR_API_KEY",

  },

Message types

How it works

URLpipe loads the page in a headless browser, listens for console errors, warnings and uncaught exceptions, then waits briefly after the page's network activity settles so asynchronous scripts have time to run and report. All captured messages are returned together.

Messages come from the page itself. Scripts inside embedded frames — ads, widgets, third-party players — log to their own console, so what you get back is your page's output rather than everyone else's.

Responses

Whatever the status, the response carries metadata headers: the result token, whether it was served from cache and how old that result is, how long we took, what it cost in credits, and the allowance you have left.
