Listed in Coinbase x402 Bazaar
Fusion Model. Independent internal reviewers assess the conversation and available tool results, a private deliberation step reconciles their guidance, and a final writer returns the next OpenAI-compatible response, including tool calls when tools are provided. Supports repeated multi-turn calls, client-executed tools, and JSON responses. Internal reviews and deliberation are not returned.

# HTTP/1.1 402 Payment Required: price, asset and payTo are in the responseEstimated calls per day
Paid calls to api.ai-open-models.com'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 7 of 16 tracked endpoints, 160 paid calls in the last 30 days. Last updated 3 hours ago. Unknown usage is left out, not counted as zero.
