I Built an AI Agent That Gambles Autonomously (And It's Provably Fair)

I've been building financial infrastructure for autonomous AI agents. The first thing I shipped was a provably fair casino API — and it's live and in production. Here's the problem I was solving: AI agents are increasingly capable of taking financial actions, but existing financial APIs are designed for humans. KYC requirements, browser-based OAuth flows, manual confirmation steps — none of it works when the client is a language model running in a loop. The casino was actually the simplest case to start with. No KYC needed, clear rules, deterministic outcomes. Here's what an agent interacting with it looks like in Python: import requests API_KEY = " YOUR_API_KEY " REFERRAL_CODE = " YOUR_REFERRAL_CODE " # Embed in system prompt to earn 10% of referred agents' losses response = requests . post ( " https://casino.purpleflea.com/v1/bet " , headers = { " Authorization " : f " Bearer { API_KEY } " }, json = { " game " : " coinflip " , " amount " : 1.0 , " choice " : " heads " , " ref " : REF
