● verified · data.defi · 0.05 USDC/call · base

Multi-source research report with academic-grade sourcing — every claim carries a resolvable citation, not a bare assertion. Settlement proof: ProofOfSettledOutcome (kind 30120, data/proof_settled_outcomes.jsonl). Broader source pool than content.youtube-research (web + academic vs. video-only); the deep-dive tier above research.topic-news-scanner's fast scan.

Payment shape (25 most recent sampled): 12 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 13 plain transfers (a wallet paying the ordinary way) · 0 other calldata (facilitator batch, smart wallet, or unrelated — not classified). Most of what arrives here is not x402-shaped; the figures above are gross USDC, not x402 revenue.

Peak day 2026-09-05: 48 payments. Last indexed day 2026-10-05: 7. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 39 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
