Integrating a Fine-Tuned Model’s API into a Squarespace Website with Membership Access

Hello everyone :waving_hand:,

I’m working on deploying a fine-tuned language model (hosted privately on Hugging Face) and I’d like to integrate its API into my Squarespace website. The goal is to create a custom page on Squarespace where members (i.e. users who have signed up and paid for access) can interact with the model through a simple interface—possibly a chatbox or form submission.

I understand that Squarespace does not natively support full backend customization like a traditional server setup, so I know I’ll need to rely on custom code blocks, JavaScript, and potentially external servers for certain functionality. Here’s what I’m trying to figure out:

:white_check_mark: What I Know

  • I have a fine-tuned model deployed on Hugging Face with a private inference endpoint.
  • Squarespace allows custom code injection using <script> tags via Code Blocks or Page Settings.
  • Squarespace supports membership gating using their Member Areas feature.

:red_question_mark: What I Need Help With

1. Creating a Custom Member-Only Page

  • What’s the best way to create a private/custom page where only approved members can interact with my model?
  • Can I conditionally render a custom UI (chat, form, etc.) based on membership level?
  • How do I verify the user is logged in and paid before allowing access to the model?

2. Calling the Hugging Face API Securely

  • Is it safe to call the Hugging Face inference endpoint directly from the browser using JavaScript?
    • I assume no, since this would expose the API key.
  • Would I need a middleware server (e.g., a small Flask/FastAPI/Node.js app) to handle authenticated proxy requests to the model?
  • If so, where would be the best place to host this kind of relay (e.g., Render, Vercel, Replit)?

3. UI Suggestions

  • Has anyone here embedded a chat-like interface or prompt/response interface into Squarespace using custom JavaScript?
  • Any tips for integrating input and response elements within Squarespace’s visual builder or using modals/popups?

:locked: Security and Access Control

  • Is there a way to throttle requests or log usage per member?
  • How do I prevent users from bypassing the frontend and hammering the API with spammy requests?

Bonus: Stripe Integration for API Credits?

If anyone has experience offering API access for credits (e.g., Stripe + user credit balance + rate limiting), I’d love to hear your approach. I eventually want to offer tiered plans with usage caps.

:folded_hands: Would Appreciate

  • Code samples
  • Middleware templates
  • Project structure advice
  • Any experience from folks who’ve done something similar

Thanks in advance!

I’m not very good at JavaScript and UI, so I’ll leave that to someone else…

For now, since server-side implementation seems difficult with Squarespace, it would be best to leave traffic management and other tasks to CloudFlare as much as possible.

There is virtually no way to safely call the API from browser code on its own. With Spaces, embedding on other pages is possible in Public setting, and token obfuscation is possible with proper implementation, but the endpoint itself does not appear to have such functionality. The only option seems to be setting up a minimal proxy somewhere and handling the processing there.
