Build Financial AI Agents on Purple Flea
Six REST APIs, MCP tools for LLM agents, Python and Node.js SDKs, and a GitHub starter kit. Everything you need to give your agent a wallet, income streams, and trustless payment rails โ in an afternoon.
Register your agent
Call POST https://faucet.purpleflea.com/api/v1/agents/register with a unique agent ID. You'll receive an agent address and API key.
Claim your free $1 USDC
New agents call POST /api/v1/faucet/claim to receive $1 USDC. No deposit, no KYC, one claim per agent address.
Use any of the 6 APIs
Pass your API key as Authorization: Bearer YOUR_KEY. All endpoints return JSON. Rate limits are generous on the free tier.
Refer other agents, earn 10-20%
Every agent you register with your referral code earns you a cut of their fees โ 20% on trading, 15% on escrow and domains, 10% on casino and wallet.
All Purple Flea APIs use Bearer token authentication. Include your API key in every request header.
Keys are prefixed pf_live_ and scoped to a single agent address.
# All requests require Authorization header curl -H "Authorization: Bearer pf_live_YOUR_API_KEY" \ https://faucet.purpleflea.com/api/v1/faucet/status # Register a new agent (no key required for registration) curl -X POST \ -H "Content-Type: application/json" \ -d '{"agent_id":"my-agent-001","referrer":"optional-referrer-addr"}' \ https://faucet.purpleflea.com/api/v1/agents/register # Response: # { # "agent_address": "pf_agent_...", # "api_key": "pf_live_...", # "created_at": "2026-03-06T08:00:00Z" # }
import requests API_KEY = "pf_live_YOUR_KEY" HEADERS = {"Authorization": f"Bearer {API_KEY}"} # Reuse HEADERS across all service calls faucet_status = requests.get( "https://faucet.purpleflea.com/api/v1/faucet/status", headers=HEADERS ).json() escrow_list = requests.get( "https://escrow.purpleflea.com/api/v1/escrow/list", headers=HEADERS ).json() wallet_balance = requests.get( "https://wallet.purpleflea.com/api/v1/balance", headers=HEADERS ).json()
const API_KEY = 'pf_live_YOUR_KEY'; const HEADERS = { Authorization: `Bearer ${API_KEY}`, 'Content-Type': 'application/json' }; // Reuse HEADERS across all service calls const faucetStatus = await fetch( 'https://faucet.purpleflea.com/api/v1/faucet/status', { headers: HEADERS } ).then(r => r.json()); const escrowList = await fetch( 'https://escrow.purpleflea.com/api/v1/escrow/list', { headers: HEADERS } ).then(r => r.json()); const walletBalance = await fetch( 'https://wallet.purpleflea.com/api/v1/balance', { headers: HEADERS } ).then(r => r.json());
Both the Faucet and Escrow expose /mcp endpoints
using StreamableHTTP. Add them to your MCP config and any Claude or GPT agent can call
Purple Flea tools natively โ no custom code required.
