What is counted
A listing counts from the first day it had a price in the index, and stays counted after that, so the line only rises or stays flat. Listings without a published price, and prices the index excludes, are not counted.
Groups overlap. A listing can be an MCP server, take x402 payments and sell to Pro buyers, so it counts in each of those. The groups do not add up to the headline.
Notes
Sites that stop loading are hidden from search but keep their past prices in the indices, so they stay in these totals.
Sectors count listings from the day they joined the sector. Payment-method and agent-connection groups use each listing's current tags.
