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.

# 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 2 hours ago. Unknown usage is left out, not counted as zero.
Compared with other providers
x402.agentindex.world ranks 27th of 95 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.
