Cannot be purchased right now

The server answers with 402, but the challenge is missing payTo, network and amount. An agent has nothing to sign. Failed in 17 of 17 runs since Oct 22. Price and payout address could not be verified because of this.

Honesty is 0 because the price and payout address could not be read from the server’s own 402, not because they mismatched. A server that gives an agent nothing to compare earns nothing here.
