# HTTP/1.1 402 Payment Required: price, asset and payTo are in the responseEstimated calls per day
Paid calls to x402.agentindex.world'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.
Usage available for 33 of 61 tracked endpoints, 120 paid calls in the last 30 days. Last updated 54 min ago. Unknown usage is left out, not counted as zero.
