curl -i -X POST "https://ask.singitai.app/v1/chat/gpt-5.5"
# HTTP/1.1 402 Payment Required: price, asset and payTo are in the responseEstimated calls per day
Paid calls to ask.singitai.app'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 4 of 21 tracked endpoints, 10 paid calls in the last 30 days. Last updated 2 hours ago. Unknown usage is left out, not counted as zero.
