The internet has had a "pay" button since 1999. Almost nobody ever used it. It's HTTP 402 — Payment Required. Sat dormant for decades because there was no standard to make it work. x402 (built by coinbase, base_ ) finally turns it on: agents and apps pay in USDC straight over HTTP. No accounts, no cards, ~200ms settlement on Base. → 169M+ payments in year one → Stripe, Cloudflare, AWS already building on it → one line of code to add a paywall Swipe for the full breakdown 👉 Save this if you're building agents. #x402 #Base #BuildOnBase #onchain #AIagents #USDC #buildinpublic #web3 #stablecoins #coinbase #cryptobuilders
