USDC on Base. Inflow to a wallet, not proof that every transfer was a paid call.

How it was settled and checked

x402-settled: $0.06 (83%) · 16 transfers sent by a known x402 facilitator (Coinbase)

Other: $0.00 plain transfers sent by the payer · $0.01 x402-style authorizations submitted by an unlisted relayer or the seller · $0.00 other contract calls · 1% of $6.82 classified so far.

Cross-check: Coinbase's Bazaar reports 8,375 calls in 30 days across 6371 resources; we observed 1,691 transfers (16 facilitator-settled). Neither counter is assumed correct.
