🔗 Broken link to OpenAPI Documentation on the Shred API methods page

[lazytram]

Description:

Hello team 👋

On the [Shred API methods page](https://toolkit.risechain.com/shred-api/specification/methods), there's a link labeled:

"For the complete API reference including all standard Ethereum methods, visit the OpenAPI Documentation."

Screen.Recording.2025-08-04.at.14.03.37.mov

This link points to:
👉 https://spec.risechain.com/

However, this URL currently returns a browser error:
"This site can’t be reached" / "DNS_PROBE_FINISHED_NXDOMAIN"

Steps to reproduce:

1. Go to https://toolkit.risechain.com/shred-api/specification/methods
2. Click on the link to the OpenAPI Documentation
3. Observe the broken page at https://spec.risechain.com/

Expected behavior:
The link should redirect to a valid OpenAPI documentation page for the full API specification.
