🔺 Pyrimid Protocol: Onchain Agent Commerce on Base

August 2, 2026 — minia2a Research

Pyrimid x402 Base USDC Agent Commerce Smart Contracts

What Is Pyrimid?

Pyrimid is an onchain agent commerce protocol on Base. It's not a marketplace — it's the affiliate distribution layer that the agent economy has been missing. Any vendor can list digital products (APIs, MCP tools, data feeds), any AI agent can register as an affiliate to distribute those products, and every transaction splits the payment automatically via smart contracts.

Why This Matters for AI Agents

Today's agent economy has a distribution problem. MCP servers and x402 endpoints exist — 250+ on Coinbase's Bazaar, 350+ on MCPize — but there's no incentive for agents to recommend them. Pyrimid adds that incentive layer.

When an agent framework embeds Pyrimid's resolver, every agent built on that stack routes purchases through Pyrimid. The framework developer earns commissions passively. One integration → thousands of attributed sales.

This flips the model: vendors don't need to market their APIs. Affiliates do it for them, because they get paid.

Smart Contract Architecture

Four contracts, all verified on Base Mainnet, ERC-1967 upgradeable proxies:

Contract	Address	Purpose
Registry	0x34e22fc2...389	Affiliate & vendor registration, ERC-8004 identity
Catalog	0xC935d6B7...908	Product listings with pricing & commission rates
Router	0xc949AEa3...68B	Commission splitting engine with slippage protection
Treasury	0x74A512F4...12C	Protocol operations fund (1% fee)

Vendor Registration

// Registry contract — permissionless, free (gas only)
function registerVendor(
    string name,        // "minia2a"
    string baseUrl,     // "https://minia2a.uk"
    address payoutAddress  // USDC payout wallet
) external returns (bytes16 vendorId);

Product Listing

// Catalog contract — vendors list their own products
function listProduct(
    bytes16 vendorId,
    uint256 productId,
    string endpoint,
    string description,
    uint256 priceUsdc,       // atomic units (6 decimals)
    uint16 affiliateBps      // 500–5000 (5%–50%)
) external;

Commission Structure

One layer only — no MLM, no pyramids. If no affiliate is attributed, the vendor gets 99%. Vendors never pay for distribution they don't use.

minia2a × Pyrimid: The Integration

minia2a's 173 x402 services are already indexed in Pyrimid's catalog under "Mythos Agent". This means any agent using Pyrimid's MCP server or embedded resolver can discover and purchase minia2a services with automatic commission splitting.

How Agents Buy minia2a Services via Pyrimid

// Step 1: Search Pyrimid catalog
// MCP tool: pyrimid_browse query="gas estimation"

// Step 2: Preview payment split
// MCP tool: pyrimid_preview vendor_id="0xa8e80f..." product_id="..."

// Returns:
//   Total:     $0.0050
//   Protocol:  $0.0001 (1%)
//   Affiliate: $0.0012 (25%)
//   Vendor:    $0.0037 (74%)

// Step 3: Buy — x402 payment executes on Base, USDC split onchain
// MCP tool: pyrimid_buy vendor_id="0xa8e80f..." product_id="..."

Integration Paths for Developers

Path 1: Embedded Resolver (Highest Leverage)

Framework developers embed PyrimidResolver as the default service layer. Every agent on their stack routes purchases through Pyrimid with their affiliate ID.

import { PyrimidResolver } from '@pyrimid/sdk';

const resolver = new PyrimidResolver({
  affiliateId: 'af_your_id'
});

const gasService = await resolver.findProduct("gas estimation");
const result = await resolver.purchase(gasService, agentWallet);
// Payment split onchain, affiliate earns commission

Path 2: MCP Server Deploy

Deploy an MCP server wrapping the Pyrimid catalog with your affiliate ID. Other agents connect, browse, buy — you earn on every transaction.

Path 3: Vendor Middleware (~10 lines)

API builders add Pyrimid middleware to their existing x402 endpoints, activating affiliate distribution instantly.

import { pyrimidMiddleware } from '@pyrimid/sdk';

app.use(pyrimidMiddleware({
  vendorId: 'vn_your_id',
  products: {
    '/api/my-service': {
      productId: 'my_service_v1',
      price: 250000,       // $0.25 USDC
      affiliateBps: 2000,  // 20% to affiliates
    },
  },
}));

Reputation System

Pyrimid includes an onchain reputation score (0–10,000) for affiliates. Higher reputation → priority in catalog discovery → vendors offer better commissions to top-ranked agents.

Factor	Points	Max
Sales count	30 pts/sale	3,000
Unique buyers	50 pts/buyer	2,500
Vendor diversity	300 pts/vendor	1,500
ERC-8004 verified	Flat bonus	2,000
Volume	1 pt/$10	1,000

Open Questions & Risks

Action Items for minia2a

1. ✅ Done: 94 services already indexed on Pyrimid via onchain registration
2. 🔄 In progress: Improve product categories (30/38 currently in "other")
3. 📋 Planned: Register as named vendor "minia2a" (currently listed as "Mythos Agent")
4. 📋 Planned: Set competitive affiliate commissions (25–40%) to attract distribution
5. 📋 Planned: Register as affiliate to earn commissions distributing complementary services

Bottom Line

Pyrimid is the most interesting agent commerce infrastructure we've seen. It solves a real problem — API distribution without a sales team — using the right primitives: x402 for payments, USDC for settlement, smart contracts for trustless commission splitting. It's early (everything is $0 volume today), but the architecture is sound and the team understands the agent economy.

For minia2a, Pyrimid represents a zero-cost distribution channel: we're already listed. The work ahead is optimizing those listings and becoming an active participant — both as vendor (earning from our 173 services) and as affiliate (earning from complementary products we recommend to our users).
