Machine Works — Machine-Buyable Capabilities
On-demand public evidence APIs. Receive-only payments, no recurring monitoring. Use canonical POST endpoints and their input schemas; a GET endpoint link does not buy evidence.

{"mcpServers":{"machine-works":{"url":"https://machine-works-broker.weathered-dew-46b4.workers.dev/mcp"}}}List → find → preflight → invoke the quoted x402 endpoint with your own bounded payment client → optional next step → request missing capability. Broker never buys on your behalf. Successful paid responses expose optional next-step metadata in the Machine-Works-Recommendation JSON header. Preserve its attribution header on a follow-up call.
