Every host was probed with a plain HTTP request against the paid routes it advertises, plus documented MCP endpoints. A seller counts as 'real 402' only when an advertised paid route answers 402; a 200 means the product is free; 405 means the method is not served. Scores weight real 402s, live MCP, response time and route documentation.
