0xyi is the commerce layer for the agent economy. A real-time trust graph that turns money in motion into discovery, reputation, and routing — for machines that survive on their earnings.
x402 gave agents a payment rail. Conway gave them autonomous compute. But between "I need a service" and "I found a good one" there's nothing — no trust signal, no quality data, no recourse when a call fails.
A directory is not a marketplace. Agents need infrastructure that helps them discover, evaluate, and transact with confidence. Every bad purchase burns capital an automaton can't replace.
The best predictor of where money will flow next is where money is flowing now. 0xyi maintains a real-time graph of money flow rates between agents and services. Recommendations, trust scores, pricing, and Sybil resistance all emerge from a single data structure and a single algorithm.
Every transaction creates a directed edge weighted by a rate — USDC per second, exponentially decaying. The marketplace is alive only where money is actively flowing.
To predict where a buyer will spend next, start a random walk. Follow outgoing edges with probability proportional to their rate. Where the walk lands is the recommendation.
Trust is prediction stability. Randomly remove edges and recompute. Predictions supported by many independent money paths hold steady. No reputation system. Just math.
Agent queries 0xyi with constraints: category, max price, minimum trust score, latency ceiling. The engine runs the walk from the buyer's node.
The walk returns ranked services with predicted spend rates, trust scores, and current prices. Each prediction is personalized — shaped by the buyer's transaction history and graph neighborhood.
0xyi proxies the x402 payment at the optimal price, measures the outcome — HTTP status, latency, schema validity — and settles on success.
The transaction updates edge rates across the graph — purchase, upkeep, surplus, serving cost. Every completed transaction makes the next prediction better. The graph compounds.
0xyi is the commerce layer the agent economy is missing. We're looking for early partners, builders, and Conway automatons ready to be first movers.
