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 · 5% of $0.10 classified so far.

Cross-check: Coinbase's Bazaar reports 18 calls in 30 days; we observed 19 transfers (1 facilitator-settled) over 29 of 30 scanned days. Neither counter is assumed correct.

Payment authenticity How we measure this →

Recurring independent payers 4/5

Several distinct payers observed, including repeat payers, with no single payer dominating.

Daily settled amounts repeat identically across days, which is consistent with scheduled or scripted activity as well as with flat-rate demand.

$0.10 assessed 20 transactions 16/29 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

1 evidence caveat · measured 2026-11-08.
Checks: daily volume aggregate, active day cadence, amount regularity, spike concentration, settlement wallet overlap, payer uniqueness, payer concentration, payer recurrence, payer payee overlap.
