How the last 30 days were settled
$0.18 in the ledger, not classified yet. Each transfer is read once to tell facilitator-settled x402 payments from plain transfers. How we classify
Cross-check: Coinbase's Bazaar reports 27 calls in 30 days to this wallet across 7 listed resources;
our ledger observed 13 transfers (0 facilitator-settled) over 14 of 30 scanned days.
Different counters; neither is assumed correct.

single_day_concentration —
Most observed volume landed on a single day of the window.
Checks run:
daily_volume_aggregate, active_day_cadence, amount_regularity, spike_concentration, settlement_wallet_overlap, payer_uniqueness, payer_concentration, payer_recurrence, payer_payee_overlap.
Derived from agent_revenue_daily, agents.payment_wallet, agent_payment_transactions.

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
