# Agent Payment Stats

> Cross-protocol agent-economy payment metrics from Barker's index. x402 (Base) volume is on-chain verifiable; ACP / AP2 / MPP / AP4M figures are self-reported claims. Separates real vs nominal volume by filtering wash/noise sellers. Use when users ask about x402 volume, agent payment stats, agent economy metrics, or the top x402 sellers. Also connects agent-payment flows to Barker's yield primitive — where autonomous agents park idle funds for yield (idle agent funds / agent 钱包生息). Powered by Barker (https://barker.money) — Yield Primitive for the Agent Economy.
