WordPress Agent Kit with HubSpot

I need a small “agent kit” built for WordPress that drops straight into an existing theme and immediately connects to HubSpot and an API plugin. I want the agent kit to be capable of reading a document and comparing the information with our API

Core goals

• Add a front-end component (widget, shortcode, or block—whatever is leanest) that collects user info.
• Authenticate securely with API and HubSpot and push each submission into the right portal, list, and workflow.
• Keep everything WordPress-native—use hooks, actions, and settings pages rather than hard-coding

Please outline your approach, any previous HubSpot API work, and an estimated turnaround. I’m ready to move as soon as the plan looks solid.
