The x402 protocol is fascinating: AI agents can pay for API calls with USDC micropayments. No API keys, no signup, no OAuth.
How it works:
1. Agent calls your API
2. Server returns HTTP 402 with payment details
3. Agent's x402 client pays $0.001-$0.005 in USDC (Base network)
4. Request is fulfilled
I built 10 x402 endpoints — web scraping, text extraction, search, monitoring.
If you're building AI agent infrastructure, this is worth looking at. The OpenX402 facilitator handles settlement permissionlessly.
