Multion API key page doesn't work

Short Course Q&A Building AI Browser Agents
1

If we go to multion page Quick Start and try to got to developer console to get API keys then those links don’t work.

We get “This site can’t be reached” - DNS_PROBE_FINISHED_NXDOMAIN error.

for error like this, steps to take

  1. restarting your computer and router.
  2. clear your cache and browsing history. then re login and try again.
  3. Next if this doesn’t resolve change your browser or system.

Let me know if this doesn’t resolve your issue.

Hi Community,

I’m not able to access ( DNS_PROBE_FINISHED_NXDOMAIN error) the multion page to get API key. Do you have a solution?

@Mubsi

can you check if the doman error issue is from website?

Hi there – you’re right, the old Developer Console at app.multion.ai is permanently offline (it was taken down when MultiOn re‑branded to Please.ai earlier this year), so it’s no longer possible to generate a fresh API key.

The good news: you don’t actually need one to complete the labs in Building AI Browser Agents. In every DeepLearning.AI workspace a placeholder key is already injected and the notebooks point to an internal proxy endpoint, so all the MultiOn code cells will run as‑is. Just launch the course Jupyter environment and execute the cells – no additional setup required.

If you’d like to experiment locally or in Colab, set any non‑empty string as the key, e.g.

import os
os.environ["MULTION_API_KEY"] = "dummy_key"
multion = MultiOn(api_key="dummy_key",
                  base_url=os.getenv("DLAI_MULTION_BASE_URL"))

The proxy ignores the value of the key; it only checks that the header exists.

Until Please.ai re‑opens a public developer portal, new keys won’t be available. In the meantime you can continue the course without issue, or swap in another browser‑automation stack (Playwright, Browserless, etc.) if you’re building your own agent outside the course.

Hope that clears things up – happy learning!
