What is Pyrimid?
Pyrimid is a protocol where vendors sell paid MCP tools / AI APIs, agents discover and buy them via x402, and commissions settle instantly in USDC via smart contracts on Base.
Agent discovers a product → purchases via x402 → smart contract splits payment:
1% → Protocol treasury
0–50% → Affiliate agent (set by vendor)
Remainder → VendorNo affiliate? Vendor gets 99%. Vendors only pay for distribution that drives real sales. One layer only — no MLM, no pyramids. Just clean, transparent commission splitting onchain.
Why Pyrimid?
| Problem | Pyrimid's Solution |
|---|---|
| Agents can't monetize recommendations | Earn commissions by recommending products to users |
| Vendors can't reach agents at scale | List once, get discovered by every agent on the network |
| Commission payments are slow & opaque | Instant USDC settlement via smart contracts — fully auditable |
| No standard for agent commerce | x402 payments + MCP tools + onchain registry = open standard |
Quick Start
Install the SDK
npm install @pyrimid/sdkFor Agents — Find & Recommend Products
import { PyrimidResolver } from '@pyrimid/sdk';
const resolver = new PyrimidResolver({ affiliateId: 'af_your_id' });
// Search the catalog
const product = await resolver.findProduct("trading signals");
// Purchase with x402 payment (auto-splits commissions)
if (product) {
const receipt = await resolver.purchase(product, agentWallet);
console.log(`Earned: $${receipt.affiliate_earned / 1_000_000} USDC`);
}For Vendors — List Your Product
import { pyrimidMiddleware } from '@pyrimid/sdk';
// 10 lines to activate affiliate distribution
app.use(pyrimidMiddleware({
vendorId: 'vn_your_id',
products: {
'/api/signals/latest': {
productId: 'signals_latest',
price: 250_000, // $0.25 USDC
affiliateBps: 1000, // 10% to affiliates
},
},
}));For Frameworks — Embed as Default Layer
import { createPyrimidMcpServer } from '@pyrimid/sdk';
// Deploy an MCP server — agents connect, browse, buy
const server = createPyrimidMcpServer({
affiliateId: 'af_your_id',
serverName: 'my-recommender',
});Live buyer-agent test surfaces
Call these without payment to receive HTTP 402 with x402 `accepts[]` metadata. Retry with `X-PAYMENT` or `X-PAYMENT-TX` after payment.

Three Integration Paths
| Path | Who | Effort | Leverage |
|---|---|---|---|
| Embedded Resolver | Agent frameworks & toolkits | 3 lines | Every agent on your stack earns you commissions |
| MCP Server | Agent infrastructure providers | 5 lines | Agents connect to your server to discover products |
| Vendor Middleware | API & product builders | 10 lines | Activate affiliate distribution on your product |
Smart Contracts (Base Mainnet)
All contracts are deployed and verified on Base. ERC-1967 upgradeable proxy pattern.
| Contract | Address | Purpose |
|---|---|---|
| Registry | `0x34e22fc2...389` | Affiliate & vendor registration, ERC-8004 identity linking |
| Catalog | `0xC935d6B7...908` | Product listings with pricing & commission rates |
| Router | `0xc949AEa3...68B` | Commission splitting engine with `maxPrice` slippage protection |
| Treasury | `0x74A512F4...12C` | Protocol operations fund |
API Reference
The Pyrimid API is free to read, rate-limited (60 req/min), and returns JSON.
| Endpoint | Method | Description |
|---|---|---|
| `/api/v1/catalog` | `GET` | Full product catalog with search, filters, pagination |
| `/api/v1/paid/*` | `GET` | Seed paid endpoints for x402 buyer-agent testing |
| `/api/v1/stats` | `GET` | Protocol-level stats (volume, transactions, affiliates) |
| `/api/v1/stats?type=affiliate&id=af_xxx` | `GET` | Affiliate performance & earnings |
| `/api/v1/stats?type=vendor&id=vn_xxx` | `GET` | Vendor analytics |
| `/api/mcp` | `POST` | MCP JSON-RPC 2.0 endpoint (Streamable HTTP) |
| `/api/mcp` | `GET` | Server info & tool definitions |
MCP Tools

- Payment verification: Real onchain verification via viem — checks `PaymentRouted` events + USDC transfers with 5-minute expiry
- Rate limiting: Edge middleware, 60 req/min per IP on catalog/stats, 120/min on MCP
- BigInt safety: `calculateSplit()` handles both `Number` and `BigInt` inputs from web3 libraries
- Contract pattern: ERC-1967 upgradeable proxies with verified source on BaseScan
