      <!-- Story -->
      <div class="mb-2" style="max-width: 46rem;">
        <p class="mb-3">Discovery finds what you have. An inventory is where that knowledge becomes durable &mdash; a centralized registry that serves as the single source of truth for every API across its whole lifecycle. For too long these lived in spreadsheets that were out of date the day they were written. A real inventory is a living surface people actually use to find and consume APIs, not a document that rots in a shared drive.</p>
        <p class="mb-3">I help you build one that captures what matters for each API: its name, identifier, version, and &mdash; critically &mdash; its owner; a description of what it does; base URL and endpoints; protocol and style; authentication; a link to the spec; lifecycle and status; known consumers and dependencies, and who is even allowed to consume it; governance and compliance tags like GDPR or HIPAA; and operational details like rate limits and uptime expectations. Clear ownership on every entry is how APIs stop getting left to rot into zombies.</p>
        <p class="mb-3">And I build it machine-readable, because that is the whole point. A spreadsheet cannot fail a CI/CD gate; an <a href="https://apisjson.org/">APIs.json</a> index built on your <a href="https://apievangelist.com/">OpenAPI</a> contracts can. When your inventory is structured data, every downstream practice &mdash; the registration gate, the traffic audit, the deprecation policy, the ownership check &mdash; can be automated against it. That is the difference between an inventory you have and an inventory that works.</p>

        <h2 class="fs-6 fw-semibold mt-4 mb-2">What you walk away with</h2>
        <ul class="text-muted">
          <li>A machine-readable APIs.json registry as the single source of truth for your APIs</li>
          <li>Every API carrying an owner, a lifecycle status, consumers, and compliance tags</li>
          <li>An inventory your pipelines and portals can query, diff, and enforce against</li>
        </ul>
