FAQ

Do I need to know how to code?

No. HPP Hub is built for builders — you describe what you want and it's generated for you.

Is HPP Hub free?

Signing up is free. Building and AI chat use Credits, which you top up as you go.

How do I pay for Credits?

With USDC.e on HPP Mainnet. See Wallets.

What can I build?

Web apps, 2D games, and 3D games. Web3 dApps are in internal testing and not yet available on the production Hub.

Which AI models can I use?

A wide range, including Claude, GPT, and Kimi models, plus free open models. The full list and pricing is on the API Keys page in the Hub — these models are served by HPP Router.

Can I use the AI models from my own code?

Yes. Create an API key on the API Keys page and call the models through HPP Router, HPP's OpenAI-compatible gateway.

Are my conversations private?

Yes. HPP Hub records only a fingerprint (hash) of each AI response on the HPP chain so you can verify it wasn't altered — your prompts and responses are not stored on-chain. See Verify a response on-chain.
