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://agent402.tools/v1/pro/messages"
# HTTP/1.1 402 Payment Required: price, asset and payTo are in the responseEstimated calls per day
Paid calls to agent402.tools'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 142 of 215 tracked endpoints, 2,981 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
agent402.tools ranks 3rd of 94 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.
