Settlement Verdict API

x402 Settlement Verdict. One paid call rules on the state of the x402 USDC settlement market on Base, computed over TensorFeed's own on-chain settlement index. Returns the market momentum (expanding, steady, contracting, or nascent versus the prior window of equal length), the concentration by Herfindahl index (concentrated, moderate, or diversified), the leading publisher, the full per-publisher volume ranking, ecosystem totals with the window-over-window change, and an AFTA-signed receipt. Optional window (24h, 7d, 30d). The "is x402 settlement growing and who leads" call, over the Base settlements TensorFeed measures, not a market-wide claim.
