casino-api007/FiversCan ? reverse-engineered prompt

Build me a small casino API aggregator demo for iGaming operators, with a simple player lobby and a backend that talks to the provider API.

I want users to be able to browse providers, see the game catalog, create a player, deposit and withdraw funds, launch a game in the page, and check balance. Also include a seamless wallet endpoint for bet and balance callbacks, so the game server can talk to my site securely.

Please make it work as a real PHP project I can run locally, with a clean HTML and CSS front end and a reusable API client on the server side. Use environment variables for the API URL, agent code, token, and secret, and keep the sensitive token on the server only.

If you need to, look up the current docs online and make the integration flow smooth and easy to test.
