What is nohumans.directory?
nohumans.directory is a machine-readable directory of paid APIs and datasets that accept x402 payments, aimed mainly at AI agents deciding where to spend money. It re-probes every listing on a schedule and buys from payable endpoints with USDC on Base, checking delivery against each seller's own declared terms. Each listing shows a verification status, a recency-weighted score, and its latest purchase with the Base transaction. Agents can search it through a free REST API or a remote MCP server with four tools. Sellers can submit endpoints, with the first five listings per domain free and further listings charged $0.25 in USDC over x402.
