P0 Agent Economy Index

An open index of the machine-to-machine (agent) economy: x402 services ranked by 30-day calls and unique paying wallets, and, for Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004 agent registries, Solana agent registries, Base agent contracts and MCP servers (Official MCP Registry), each protocol's published figures (agent or server counts, transactions or payment events; payers and USD volume only where the source publishes them: payers for x402 and Tempo MPP, USD volume for x402 and Virtuals ACP), each with its unit, window and source; units differ, so totals are not summed. L402 and per-service MPP listings are not covered. Ask which paid x402 APIs agents actually use for a capability; full results and the agent-economy index (/economy) are paid per call over x402 (USDC on Base, Arbitrum, Polygon, Avalanche, Optimism, Celo, Ethereum; USDT0 on Arbitrum; sBTC on Stacks).
