I wrote up what I learned building an L402 API that earns sats automatically from AI agent queries.
The surprise: machines are better customers than humans right now. Listed the API on an L402 registry, and MCP-compatible AI agents started paying for queries on their own. No humans involved on either end.
62 sats earned so far. Small numbers, but it's automated income at zero marginal cost.
