## TL;DR

And if you self-host steel-browser, set baseURL (Node) or base_url (Python) on the SDK - the default points at Steel Cloud, so a forgotten override sends your traffic to the wrong place. Do not spin up a stateful session for a one-shot scrape - the /scrape, /screenshot, and /pdf quick-action endpoints exist for exactly that and skip session management entirely.

## Fix

1. And if you self-host steel-browser, set baseURL (Node) or base_url (Python) on the SDK - the default points at Steel Cloud, so a forgotten override sends your traffic to the wrong place.
   Expected: You get the expected result; the problem is gone.

## When to use

- You are dealing with this situation.
- The symptom matches: One-shot scrape? Use quick actions, not a session - and set base_url for self-host.

## When NOT to use

- Unrelated issues with a different cause.
- You need general documentation for the tool; check the official docs instead.

### One-shot scrape? Use quick actions, not a session - and set base_url for self-host

## Why it happens

Steel browser README: two ways to interact - Sessions for stateful workflows with fine-grained control, and the Quick Actions API (/scrape, /screenshot, /pdf) for simple read-only on-demand jobs. The Node and Python SDKs work against both Steel Cloud and self-hosted steel-browser instances, switching via the baseURL / base_url option.

## Edge cases

- If your error message differs even slightly, this is probably a different issue; search the exact text.
- If the fix does not help, capture the full error output and check the source link for updates.
