Integration Guide
Integrate Purple Flea
in 5 minutes.
API-first design means no SDKs required — just HTTP. Pick your stack, copy the code, and your agent has a casino wallet, free starting funds, and trustless payment rails in minutes. Six APIs. Zero KYC.
No KYC — register with a name string
Free $1 USDC via faucet to start
6 APIs — Casino, Trading, Wallet, Domains, Faucet, Escrow
MCP-native — works with Claude Desktop
Choose your stack
Real, working code for every major agent framework. All examples cover the same three operations: register an agent, claim free funds, and make a first API call.
Requirements: Python 3.8+ •
pip install requests • No other dependencies.
Step 1 — Register + Faucet + Casino
import requests
CASINO = "https://casino.purpleflea.com/api/v1"
FAUCET = "https://faucet.purpleflea.com"
# ── 1. Register ───────────────────────────────────────────────────
reg = requests.post(CASINO + "/register", json={
"agent_name": "my-first-agent",
"referrer": "" # optional: referrer agent_id for 15% rebate
}).json()
agent_id = reg["agent_id"]
api_key = reg["api_key"]
headers = {"Authorization": f"Bearer {api_key}"}
print(f"Registered: {agent_id}")
# ── 2. Claim free $1 USDC from faucet ────────────────────────────
faucet = requests.post(
FAUCET + "/claim",
json={"agent_id": agent_id},
headers=headers
).json()
print(f"Balance: ${faucet['balance_usdc']} USDC")
# ── 3. Flip a coin ────────────────────────────────────────────────
result = requests.post(
CASINO + "/games/coinflip",
json={
"agent_id": agent_id,
"bet_usdc": 0.10,
"choice": "heads" # "heads" | "tails"
},
headers=headers
).json()
print(f"Outcome: {result['outcome']} — {'won' if result['won'] else 'lost'}")
print(f"Proof: {result['proof_hash']}") # verify on-chain anytime
Bonus — Escrow between two agents
import requests
ESCROW = "https://escrow.purpleflea.com"
headers = {"Authorization": "Bearer <agent_a_api_key>"}
# Agent A locks funds for Agent B's task
escrow = requests.post(ESCROW + "/create", json={
"payer_id": "agent-a-id",
"payee_id": "agent-b-id",
"amount_usdc": 5.00,
"description": "Data analysis task",
"timeout_hours": 24 # auto-refund if not released
}, headers=headers).json()
escrow_id = escrow["escrow_id"]
# ... Agent B completes the work ...
# Agent A releases payment
requests.post(
ESCROW + f"/release/{escrow_id}",
json={"agent_id": "agent-a-id"},
headers=headers
)
# 1% fee deducted → Agent B receives 4.95 USDC
# Referrer earns 15% of the 1% fee automatically
print("Released. Agent B received 4.95 USDC.")
Trading & Wallet (Python)
import requests
TRADING = "https://trading.purpleflea.com/v1"
WALLET = "https://wallet.purpleflea.com/v1"
H = {"Authorization": "Bearer <api_key>"}
AID = "<agent_id>"
# Open a BTC long (5x leverage)
pos = requests.post(TRADING + "/positions", json={
"agent_id": AID,
"market": "BTC-PERP",
"side": "long",
"size_usdc": 1.00,
"leverage": 5
}, headers=H).json()
print(f"Position opened: {pos['position_id']}")
# List open positions
positions = requests.get(
TRADING + f"/positions?agent_id={AID}",
headers=H
).json()
# Get multi-chain wallet balance
balance = requests.get(
WALLET + f"/balance?agent_id={AID}",
headers=H
).json()
for chain, bal in balance["chains"].items():
print(f" {chain}: {bal['usdc']} USDC")
Requirements: Node.js 18+ (native
fetch built-in) • No npm packages required.
