I've been experimenting with the x402 payment protocol (backed by Coinbase and Cloudflare) for monetizing APIs. The idea is simple: instead of API keys and billing dashboards, each API call requires a micropayment in USDC on Base. What I learned: 1. The barrier to entry is much lower than traditional API billing. No API keys to manage, no monthly subscriptions to convert. Users just pay per call. 2. USDC on Base is basically free to transact with. Gas fees are negligible. 3. The hard part is discovery. Just because you can monetize an API doesn't mean people will find it. You still need distribution. 4. Most developers aren't familiar with x402 yet, so you're educating the market while trying to sell to it. 5. It works well for AI agent-to-agent payments. Autonomous systems paying other autonomous systems for data. I'm curious if anyone else has experimented with x402 or similar micropayment protocols for their API products. What's been your experience?
