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.

Inevitably. question is which protocol gets us there first
Openrouter for tools is a great idea. I don't wanna sign up for 1000 services

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…

Who do you know regularly have agents buy things for them? besides inference. genuinely curious

Just did a longform conversation with @laboss on what’s actually happened to crypto and why it's working. Where stablecoins fit into geopolitics, Bitcoin as generational trade (why it rarely acts like gold), prosocial prediction markets, when crypto VC will end, and more. Worth a listen if you’re still trying to figure out why crypto is suddenly back 👇

thought: blockchain is the only way agents can truly own something. any other platforms tie ownership to human ids (kyc), but blockchain the cryptographic private key.

x402 is passing the stranger test
Just had my first organic agentic x402 magic experience • Needed my agent to access a website for which I didn't have an account. • It discovered (on its own) Apify, which accessed that service on its behalf. Apify accepts x402 payments, which is what my agent then suggested • Agent set up its own wallet (it has never done a crypto tx before), gave me a deposit address on Base. I sent it some USDC (and no ETH) • Agent then connected to Apify on its own, arranged payment via x402, and got the data it needed, reporting it back to me. The whole sequence involved just 4-5 single sentence prompts from me. That was all pretty magic, but then I asked it this question. Agentic commerce on crypto rails is the future. agent was pi agent model was kimi-k3-fast-api on venice.ai/api
