How to buy

This endpoint takes pay-per-call payments over x402. Call it once without paying to see its live price; any x402 client then pays and retries automatically.

curl -i -X POST "https://ask.singitai.app/v1/responses"
# HTTP/1.1 402 Payment Required: price, asset and payTo are in the response

Estimated 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 18 of 40 tracked endpoints, 52 paid calls in the last 30 days. Last updated 1 hour ago. Unknown usage is left out, not counted as zero.

Compared with other providers

ask.singitai.app ranks 44th of 112 in LLM inference by its latest reported 30-day paid calls. Coverage matters: a provider whose endpoints report more of their usage can rank higher.
