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

How it was settled and checked

x402-settled: $0.00 (0%) · 0 transfers sent by a known x402 facilitator

Other: $137.56 plain transfers sent by the payer · $21.78 other contract calls · 91% of $176.02 classified so far.

Cross-check: Coinbase's Bazaar reports 7 calls in 30 days; we observed 10 transfers (0 facilitator-settled) over 21 of 30 scanned days. Neither counter is assumed correct.
