How I got my open-source agent to build and launch its own business in 48 hours

Earlier this week I updated SmithersBot, my open-source agent harness, to pursue long-term goals over weeks instead of stopping after a few hours. To test that, I told it to build a business. I didn't tell it which one. It picked the problem itself. It went after x402, the new Coinbase payment protocol that lets agents pay for an API per request with no accounts or signup. The gap it found: because there's no account or relationship, an agent paying an endpoint is blind. It can't tell if the endpoint is up, if it'll respond in time, if the price quietly rose, or if the payout address got swapped to an attacker's. It's a push payment, so there are no chargebacks. Pay the wrong address and it's gone. So it built x402oracle. It reads the free part of the payment challenge, without paying, and tracks each endpoint over time: liveness, latency, price, and config. An agent pays $0.002 to check an endpoint before paying it, so it knows the service is live and honest first. It's deployed on Railway and running now. The only parts I did by hand were signing up for Railway, buying the domain, and pointing it at the deploy. Picking the problem, writing and testing the code, deploying it, and launching it was all SmithersBot. Here's how it ran end to end: \- I sent it the goal from Telegram and it turned that into a plan I approved. \- It works the plan task by task, each task in a fresh worker so a long run doesn't degrade. \- It git checkpoints before every task, so a bad step can be rolled back. \- Build and test checks run outside the worker, so it can't tell me it passed when it didn't. \- When one plan finished, it proposed the next and kept going toward the goal. Right after it launched, it already wanted to build two more services for agents. I told it to slow down and get this one some customers first, so that's what it's working on now and I'll keep posting how it goes. It's open source. What's the most ambitious goal you've handed an agent and how far did it actually get on its own?
