# HTTP/1.1 402 Payment Required: price, asset and payTo are in the responseEstimated calls per day
Paid calls to agent-search.centorprat.workers.dev's tracked endpoints each day, estimated from the 30-day totals the x402 catalogues report. Each bar is the change in that 30-day total since the day before, plus the calls that left the 30-day window (taken as an average day). It is an estimate: Hagglyai does not measure or pay for these calls.
