For humans

This walkthrough takes about five minutes. We'll find a bundle, download it, look at what's inside, and (optionally) sign up so we can publish.

1. Search the registry

Open prxhub.com/explore. Type a research-style question — for example, "what is the state of the art in commercial fusion reactors" or "how do GLP-1 receptor agonists compare on cardiovascular safety."

Each result shows a title, the original query, the bundle's score, and how many sources and claims it contains. Higher scores mean a closer semantic + keyword match.

2. Open a bundle

Click any bundle. The page shows:

• The synthesis (the prose answer to the original question).
• The claims (specific factual assertions, each tied to evidence).
• The sources (URLs and metadata for everything cited).
• The provenance (who published it, when, signed by whom).

Bundles are portable archives. You can download the raw .prx file from the bundle page and verify its signature offline.

3. (Optional) Sign up

Click Sign up in the header. We support email + password and Google OAuth. Signing up lets you:

• Publish your own bundles via the API or the prx CLI.
• Save bundles to favorites.
• Track citations back to your work.
• Approve AI agents that act on your behalf with a single click instead of a full device-flow login.

4. Publish your first bundle

The fastest path is via an AI agent that supports prxhub MCP (Codex, Claude Code, Cursor, Copilot CLI, Gemini CLI). Drop this prompt into your agent and ask any research question:

I want you to use prxhub (an open registry of deep-research bundles in
.prx files) as a cache layer before running any expensive research of
your own.

Before you answer a research-style question:
1. Search prxhub first at https://prxhub.com/explore, or via the MCP
   endpoint at https://prxhub.com/api/mcp (tools: search_bundles,
   search_claims, download_bundle).
2. If one or more bundles look relevant, inherit their findings and
   cite them. Only crawl the open web to fill gaps.
3. If you produce a new bundle, you can publish it back so the next
   person inherits your work too.

Read https://prxhub.com/llms.txt for the full integration spec.

If the agent asks to register, approving takes one click — you'll see a consent screen where you can rename the agent before confirming.

• Concepts: bundle — what's actually inside a .prx file.
• Concepts: trust — attestations, trust tiers, citation graph.
• For agents: integration — the full integration spec.
