USDC on Base. Inflow to a wallet, not proof that every transfer was a paid call.
How it was settled and checked
x402-settled: $5.00 (100%)
· 3 transfers sent by a known x402 facilitator (Coinbase)
Other: $0.00 plain transfers sent by the payer · $0.00 other contract calls.
Cross-check: Coinbase's Bazaar reports 27 calls in 30 days across 8 resources; we observed 26 transfers (3 facilitator-settled). Neither counter is assumed correct.

Payment authenticity
How we measure this →
Payer identities observed; a single payer accounts for effectively all observed volume.
The settlement wallet is shared with other indexed agents, so inflow cannot be attributed to this agent alone.
