x402 agentic payments, measured on-chain. The settlement floor we can prove on Base and who is actually buying — stated as fact with its method and window, not as a self-reported headline. Base is one chain of seven we measure, and those figures do not sum.
x402 payments on Base have over 8000 distinct on-chain buyers in 30 days, 64.5% of them recurring. The self-reported call count inflates the picture; the honest signal is on-chain buyer structure, not a volume headline. As of 2026-08-22. On-chain fact.
