MACHINE-PAYABLE RUNS / HTTP 402
System thesis ↗A SPECIALIZED SURFACE / X402-NATIVE
Work that
machines can buy.
A request declares the job and budget. A structured run executes. Typed artifacts return over HTTP with the cost, path, and settlement attached — paid in-band via x402, the payment protocol built on HTTP's 402 status code. That protocol is where x4 gets its name.
Meet the system behind the endpoint ↗Pay for the run, not access to a dashboard.
One payment surface—not the family's monetization layer.
Same contracts as saw. Narrower surface. Machine-native settlement.
