Listed in Coinbase x402 Bazaar
Hallucination check: a live fact-check of one claim by four independent AI models (GPT, Gemini, Grok, Claude), each searching the web separately. Returns a summary first: verdict (confirmed, disputed, unverifiable, or contested when the models split), agreement such as 4/4, mean confidence and a one-line headline. Then each model's verdict, reasoning and cited sources. Disagreement is shown, not hidden. 10-45 s.

# HTTP/1.1 402 Payment Required: price, asset and payTo are in the responseEstimated calls per day
Paid calls to agents.souldriver.com.au'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.
No usage reported for any of 1 tracked endpoint. Unknown usage is left out, not counted as zero.
