A full pull of Coinbase's x402 Bazaar: 60,477 listings, 883K paid calls in 30 days, six in ten listings with exactly one payer, and the top ten endpoints taking 48.5% of all traffic. The catalog doubled in the last week of October. Demand didn't. What the marketplace's own numbers say about where payers actually land.

Block plugged Lightning into x402, Cardano and Algorand shipped rails the same week, Solana moved batch settlement to preview — and the audited agentic share still reads 0.6 to 7.5 percent. Rail supply is not demand.

TRM Labs measured the agentic share of x402 from the chain. One month on our own paid routes, read directionally: the meter hums, the rail settles everything, the cheap legible tier converts first. Conversion is the wall.

Coinbase's tokenized stocks landed on Base, the same chain carrying x402 agent payments. The paid data layer in between is the builder gap.

AWS took agent payments to GA while Bazaar grew to 15,100 resources. The scarce layer is deciding what deserves a payment.

Base MCP gives agents a wallet path. AgentToll packages x402 work products agents can inspect, cap, approve, and receipt.

Linux Foundation governance, Visa and Artemis usage data, and what the x402 Foundation launch means for builders shipping paid agent tools.
