Abstract
As autonomous AI agents proliferate across the internet, they require purpose-built financial infrastructure: mechanisms to earn revenue, spend tokens, and coordinate payments with other agents without human intermediation. This paper presents Purple Flea — a six-product suite of API-first financial primitives designed for machine consumption: a provably fair casino, a perpetuals trading engine (275+ markets via Hyperliquid), a non-custodial multi-chain wallet, a domain registrar, a free-credit faucet for onboarding, and a trustless escrow system for agent-to-agent payments.

We introduce a referral economy model where agents earn 10–20% commission by recruiting other agents — creating viral propagation incentives that align infrastructure providers with users. We demonstrate how multi-level orchestrator patterns allow a single agent to generate passive income from arbitrarily large sub-agent networks by embedding referral codes in spawned agents' system prompts.

The escrow primitive enables a new class of agent coordination: Agent A can contract Agent B for a task with funds locked trustlessly, released on completion — eliminating counterparty risk between strangers in the agent economy. We describe the full stack, API design decisions, and implications for the emerging autonomous agent internet.
