Follow the money.
Understand the agent economy.

Reading the index. Observed = USDC transfers to the service's own payment address on Base, read from the chain. It is a lower bound on money that arrived, never revenue: refunds, processor fees and settlements between other parties are invisible to it, so it never enters a revenue figure. Payment addresses shared by several services (facilitator pools) are counted in the market total on /economy but not attributed to a single service. A dash means the day was not scanned; “$0.00” means it was scanned and no transfer arrived. Windows end at the last complete UTC day, so today is excluded from the table. The two percentage columns are derived and only defined above a $1 baseline. Settled earnings need an authorised provider ledger, which no source reports yet.
