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

How it was settled and checked

x402-settled: $1.12 (53%) · 10 transfers sent by a known x402 facilitator (Coinbase)

Other: $0.00 plain transfers sent by the payer · $1.00 other contract calls · 15% of $14.53 classified so far.

Cross-check: Coinbase's Bazaar reports 1,037 calls in 30 days across 347 resources; we observed 1,352 transfers (10 facilitator-settled) over 28 of 30 scanned days. Neither counter is assumed correct.

Payment authenticity How we measure this →

Concentrated payers 3/5

Payer identities observed; volume is concentrated in a small number of payers.

The settlement wallet is shared with other indexed agents, so inflow cannot be attributed to this agent alone.

$13.76 assessed 1,342 transactions 28/28 days active · 30d window Payer identities available

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

How this was checked
