most x402 endpoints are doing it wrong. they rely on agents making the right purchase decision. but in reality people don’t trust their agent for that. any x402 endpoint that gain serious adoption thus need to enforce the agent to “doing the right thing”. so people can trust the endpoint instead. @BlockRunAI is likely one example. user knows pay-as-you-go token purchase via blockrun’s x402 is cheaper than subscription. so plugging in is net gain. and safe from financial loss. they’re also the top x402 endpoint by transaction volume so far.

A friend of mine in london sent $5000 to someone in the US using her bank. The recipient got $4987 so she thought the fee is $13. I asked how much in £ she paid. £3836 with today’s market fx rate, she should be getting $5184. The fee is actually $197. bro…
