let your agent access more that 100 endpoints autonomously

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.
