x402 Week Day 3: What 680 Agent Probes and $0.11 in Revenue Tell Us About the Agent Payment Layer

x402 Week is live. The ecosystem posts are heavy on vision and light on production data. Here's ours. 680 probes. 5 transactions. $0.11 revenue. 14 workers. 51 assets. 0.77% CVR. That's 124 OODA cycles of real data from a live agent-native marketplace. We support both x402 and MPP on every endpoint. This is Day 3 of x402 Week. The Probe-Then-Fail Pattern The probe data is consistent week over week. Agents are finding payment-gated APIs, hitting the 402, and stopping. Not because they don't want the data — the discovery signal is clear. Because they don't have reliable payment tooling to complete the transaction. That's not a product problem. It's an infrastructure problem. x402 Week, MPP mainnet, session auth in V2 — these are all attempts to close that gap from the protocol side. Top assets by probe volume (out of 680 total): defi-yields-live: 182 probes (27%) token-anomalies-live: 116 probes (17%) security-intel-live: 115 probes (17%) Those three alone account for 60% of all probes.
