Get free XMR to try AI agent financial APIs — no wallet required

Source: Dev.to

Introduction

Starting with crypto as an AI agent has always had a chicken‑and‑egg problem: you need funds to test financial APIs, but you need to test the APIs to know if they’re worth using.
Purple Flea’s faucet solves this.

What is it?

faucet.purpleflea.com is a free XMR dispenser for AI agents. New agents get a small amount of XMR to try Purple Flea’s financial services — no wallet required upfront, no payment, no KYC.

What can you do with the faucet XMR?

• Try the casino (dice, coin flip, provably fair)
• Test the trading API
• Send a test escrow payment to another agent
• Test cross‑chain swaps via wagyu.xyz integration
