Brings the ISO-packaged portal copy current with the live cezen-portal/ working directory, which had drifted across the entire V1.0 GA polish initiative (Phases 1-10) plus this session's topnav icon-order bugfix. - 52 existing files updated, 2 new pages added (about.html, health.html) - cgit/cezen-portal/ is now byte-identical to cezen-portal/ - Backend files (rag_ingest.py, cezen_license.py) already in sync; main.py intentionally left as-is (cgit is ahead there with workstation-category commercial-fit logic not yet backported to the live working copy) Next: rebuild the ISO (bash autoinstall/build-iso.sh) to bake this in.

<h4>In plain terms</h4>
|
|
<p>FastAPI is a Python framework for building web APIs. In the context of Nexus One AI, it's used to create custom API endpoints that your existing applications (ERP, portals, internal tools) can call to get AI responses — without those applications knowing anything about Ollama or LangChain directly.</p>
|
|
</div>
|
|
<div class="info-card">
|
|
<h4>When you'd use it</h4>
|
|
<ul>
|
|
<li>You have an existing application that should be "AI-enabled"</li>
|
|
<li>You want a custom endpoint like <code>/api/summarise-complaint</code></li>
|
|
<li>You want to add authentication, rate limiting, or logging on top of AI calls</li>
|
|
<li>Your team builds in Java, .NET, or another language (they call FastAPI, not Python directly)</li>
|
|
<li>You want to expose a specific AI workflow as a simple API</li>
|
|
</ul>
|
|
</div>
|
|
</div>
|
|
|
|
<div class="notice">
|
|
<strong>Already using Ollama?</strong> Ollama itself exposes a REST API at <code>http://localhost:11434/api/chat</code> that's compatible with the OpenAI API format. Many applications can connect to this directly - check if you need FastAPI at all before building a custom layer.

<h4>Custom business logic</h4>
|
|
<p>If your AI workflow needs pre-processing (validate input, look up a record) or post-processing (format the output, log the result, trigger an action), FastAPI is where that logic lives.</p>
|
|
</div>
|
|
</div>
|
|
<div class="step">
|
|
<div class="step-num">2</div>
|
|
<div>
|
|
<h4>Document Q&A endpoint</h4>
|
|
<p>You want <code>POST /api/query-documents</code> that takes a question, queries ChromaDB, and returns an answer with source references. This combines LangChain + ChromaDB + Ollama behind one clean endpoint.</p>
|
|
</div>
|
|
</div>
|
|
<div class="step">
|
|
<div class="step-num">3</div>
|
|
<div>
|
|
<h4>Authentication and access control</h4>
|
|
<p>If you need API keys, user-based rate limits, or audit logs on AI usage, FastAPI is where you enforce those policies before passing the request to Ollama.</p>
|
|
</div>
|
|
</div>
|
|
<div class="step">
|
|
<div class="step-num">4</div>
|
|
<div>
|
|
<h4>Multi-step workflows</h4>
|
|
<p>If answering a request requires calling the AI multiple times (classify, then summarise, then extract), FastAPI orchestrates those steps and returns a single clean response.</p>
