USDC inflows on Base. Reproducible via eth_getLogs on USDC Transfer events to the wallet. Inflow to a wallet, not proof that every transfer was a paid call.
How the last 30 days were settled
x402-settled: $2.00 (45%)
· 1 transfer sent by a known x402 facilitator (Coinbase)
Other: $0.00 plain transfers sent by the payer · $2.45 other contract calls · 94% of $4.72 classified so far.
How we classify
Cross-check: Coinbase's Bazaar reports 10 calls in 30 days to this wallet across 4 listed resources;
our ledger observed 20 transfers (1 facilitator-settled).
Different counters; neither is assumed correct.

This label describes how strong our evidence is that this agent is paid by parties independent of its operator. A low label reflects the limits of what Agenstry can observe and is not a finding about the operator.
Full metric breakdown — payer concentration, wallet exclusivity, cadence and the
7 / 30 / 90-day trailing windows — is available through the paid
