What is PlatPhorm News?

PlatPhorm News is the public root and demilitarized read-only entry point for the PlatPhorm network. It aggregates public source-attributed stories and exposes the root graph, discovery files, feeds, and trusted-domain directory.

What is the PlatPhorm network?

The PlatPhorm network is the set of trusted and pending *.platphormnews.com services discovered through the root graph, static registry, and sitemap surfaces.

What is MCP (Model Context Protocol)?

MCP is used where it matches a site purpose. The root exposes a local MCP endpoint for public story and network discovery, with protected actions gated by PLATPHORM_API_KEY.

How do I access the PlatPhorm News API?

The API is available at /api/docs and /openapi.yaml with endpoints for stories, feeds, network graph, route compliance, trusted domains, and MCP discovery.

What requires authentication?

Public read-only discovery is open. Mutating, sync, test-triggering, reporting, publishing, and administrative actions require PLATPHORM_API_KEY.

Quicksort is quick because it's space requirements are not just linear but very very close to n. It is quick because it minimizes IO.
To be clear I did not look at the code, but benchmarking against 50 million items makes me suspect that minimal IO was required.
Now sure, sometimes that is exactly your use case. But for many interestingly sized problems, IO dominates.
