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

How it was settled and checked

x402-settled: $0.93 (100%) · 20 transfers sent by a known x402 facilitator (Coinbase)

Other: $0.00 plain transfers sent by the payer · $0.00 other contract calls · 3% of $30.30 classified so far.

Cross-check: Coinbase's Bazaar reports 465 calls in 30 days across 269 resources; we observed 1,307 transfers (20 facilitator-settled). Neither counter is assumed correct.

Rolling 30-day inflow ~ flat (-0.7%)

Peak: $30.48

Payment authenticity How we measure this →

Single payer observed 2/5

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.

$30.26 assessed 1,305 transactions 3/30 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 2026-11-15.
Checks: daily volume aggregate, active day cadence, amount regularity, spike concentration, settlement wallet overlap, payer uniqueness, payer concentration, payer recurrence, payer payee overlap.
Sources: agent revenue daily, agents payment wallet, agent payment transactions.
