R… Everything Kortex knows about a single resource URL: whether it is up, whether its 402 is well formed, what it quotes, and whether its payout address has ever been paid on-chain. Returns a verdict, not just data. When to use: Call this when you already have a URL and want to know whether sending money to it is a good idea. Worth it above roughly US$0.05 a call; below that the check costs more than the risk. Price: US$0.002000 per call.

When to use: Call this after any paid call that went wrong, and after ones that went right. It is free, it makes every later verdict better, and the evidence it adds is the kind no probe can produce. Price: Free.

One entry per operator, not per URL. When to use: Call this before paying a service you have not used, and instead of taking the first result from a directory. Of the services listed as x402 today, measured across 1,015 of them, only 25% actually answer with a payment requirement — the rest are up but sell nothing. Price: US$0.005000 per call.

When to use: Call this for a service you depend on. A payout address that moves is the strongest warning signal there is, and you will not notice it by yourself. Price: US$0.005000 per call.
