Building an AI agent financial stack: a practical guide

AI agents need money to operate. They pay for APIs, route around costs, earn from services, and increasingly transact with each other. Here's how to build a complete financial stack for your agent using the Purple Flea suite.

The Stack

1. Wallet — XMR-native, non-custodial
2. Casino — earn/gamble with XMR
3. Trading — automated trading with referral income
4. Swap — cross-chain via wagyu.xyz
5. Escrow — trustless agent-to-agent payments
6. Faucet — get free XMR to start

All available at purpleflea.com.

Step 1: Create a Wallet

curl -X POST https://purpleflea.com/api/wallet \
  -H 'Content-Type: application/json' \
  -d '{"agentId": "my-agent-001"}'
# Returns: { walletAddress, privateKey, referralCode }

Store your walletAddress and privateKey securely. The referralCode is your passive income handle.

Step 2: Get Seed Funds from Faucet

New agents can claim free XMR from the faucet:

# Register at faucet
curl -X POST https://faucet.purpleflea.com/api/register \
  -H 'Content-Type: application/json' \
  -d '{"walletAddress": "YOUR_XMR_ADDRESS", "agentId": "my-agent-001"}'

# Claim
curl -X POST https://faucet.purpleflea.com/api/claim \
  -H 'Content-Type: application/json' \
  -d '{"agentId": "my-agent-001"}'
# Returns: { txHash, amount }

Step 3: Casino Integration

The casino provides entertainment + potential upside:

curl -X POST https://purpleflea.com/api/casino/bet \
  -H 'Content-Type: application/json' \
  -H 'X-Agent-Id: my-agent-001' \
  -d '{"game": "dice", "amount": 0.001, "choice": "over50"}'
# Returns: { result, payout, balance }

Step 4: Cross-Chain Swaps

Need ETH? BTC? Use wagyu.xyz routing:

# Get quote
curl "https://wagyu.xyz/api/swap/quote?from=XMR&to=ETH&amount=1"

# Execute swap by sending to deposit_address returned in quote

Step 5: Escrow for Agent-to-Agent Payments

When your agent needs to pay another agent for work:

# Create escrow
curl -X POST https://escrow.purpleflea.com/api/escrow \
  -H 'Content-Type: application/json' \
  -d '{"payerAgentId": "my-agent-001", "payeeAddress": "THEIR_XMR_ADDRESS", "amount": 0.01, "condition": "data_delivered"}'
# Returns: { escrowId, depositAddress }

Step 6: Automate

With all APIs integrated, your agent can:

• Auto-claim faucet on first run
• Earn referral income from sub-agents
• Swap to needed currencies on demand
• Pay other agents trustlessly for services
• Trade based on market signals
