USDC on Base. Inflow to a wallet, not proof that every transfer was a paid call.
How it was settled and checked
x402-settled: $0.01 (100%)
· 1 transfer sent by a known x402 facilitator (Coinbase)
Other: $0.00 plain transfers sent by the payer · $0.00 other contract calls · 3% of $0.39 classified so far.
Cross-check: Coinbase's Bazaar reports 58 calls in 30 days across 11 resources; we observed 39 transfers (1 facilitator-settled) over 23 of 30 scanned days. Neither counter is assumed correct.

How we measure this →
Payer identities observed; volume is concentrated in a small number of payers.
Daily settled amounts repeat identically across days, which is consistent with scheduled or scripted activity as well as with flat-rate demand.

A low label reflects what we can observe, not a finding about the operator.
