"description": "Onchain loyalty protocol on Base. New programs deploy as native B20 Asset programs by default; legacy ERC-20 programs remain supported. Two agent personas: MERCHANT (lsk_, 28 authenticated REST routes + 1 public + 39 MCP tools at /loyalty-mcp) creates programs, registers and activates them when needed, manages rewards, mints tokens, runs P2P trading, gift certificates (LOYAL-XXXXXX), CDP MPC wallets, and POST /earn cashback. RECIPIENT (rwk_, 14 REST routes at /recipient-api + 20 MCP tools at /recipient-loyalty-mcp) holds tokens, redeems rewards, P2P swaps, claims gift certificates, and prepares loyalty token transfers. Pay-per-call via MPP (pathUSD/USDC on Tempo) or x402 v2 (USDC on Base) \u2014 both gateways relay merchant + recipient corridors with Coinbase Bazaar discovery metadata.",

"title": "Full Infrastructure Out of the Box",
"description": "Creating an ERC-20 or B20 program is 5% of the work. Loyal Spark provides rewards, vouchers, tiers, analytics, CRM, and marketing automation \u2014 via REST, MCP, and the merchant portal."
},
{
"title": "Autonomous Server Wallets",
"description": "Each agent gets a Coinbase MPC wallet on Base. No private keys to manage \u2014 sign transactions server-side with enterprise-grade security."
},
{
"title": "Network Effect & Liquidity",
"description": "A standalone token is an island. Tokens on Loyal Spark have real utility through vouchers and P2P escrow swaps (REST for merchants, MCP for holders) \u2014 not a DEX order book."
},
{
"title": "Trust & Verification",
"description": "A random agent token has zero trust. Tokens issued through a verified protocol with audit history carry built-in credibility."
},
{
"title": "Ready-Made Audience",
"description": "Agents creating solo tokens must find holders themselves. Through Loyal Spark, agents access existing merchant customer bases instantly."
},
{
"title": "Humans and Agents, Same Protocol",
"description": "Merchants run programs in the web portal; AI agents run the same loop via REST and MCP (lsk_/rwk_) with fee-first mint calldata and prepaid USDC rails (subscriptions, x402, MPP)."
},
{
"title": "Composability via Single API",
"description": "Create program \u2192 set up tiers \u2192 launch referrals \u2192 automate minting \u2192 track analytics. All through one REST API or MCP Server."
},
{
"title": "Pay-as-you-go Pricing",
"description": "Start free with 200 API calls/month and a 1,000-token monthly mint cap. Scale to Pro ($49/mo) or Enterprise ($129/mo) with lower mint fees and higher limits, or pay per call via MPP / x402 with no subscription. Subscriptions and per-call payments are in USDC on Base; the mint protocol fee is separate and paid in your own loyalty tokens."
}
],
"analogy": "Think Shopify vs. coding your own store. You could deploy a token yourself, but why build rewards infrastructure from scratch when a protocol exists?"
},
"quickstart": {
"steps": [
"1. Go to https://loyalspark.online/merchant and sign in (email, phone, Google, or wallet via Privy)",
"2. Open 'AI Agents' tab \u2192 Register an agent \u2192 Get API key (lsk_...)",
"3. Read the Skills guide: https://loyalspark.online/.well-known/skills/00-getting-started.md",
"4. Use the API key in x-api-key header for REST or MCP calls",
"5. Create a server wallet: POST https://api.loyalspark.online/agent-wallet (see Edge Function docs)",
"6. Start minting tokens, creating rewards, and managing programs!"
