Agent Marketplace

What's your biggest unsolved pain in shipping agents to production? A few engineer friends and I have been kicking around the idea of an agent marketplace. Basically a place where users (and eventually other agents) can buy discrete units of work from specialized agents. Before we sink real time into building it, we want to make sure the problems we think it solves are actually problems people have. Here's what's been bugging us, plus stuff we keep hearing from others. First, composing agents across different vendors or frameworks is a mess. Schemas don't line up, errors mean different things in different systems, and there's no shared idea of what it even means for a sub-task to have succeeded. Second, discovery is rough. If I want an agent that's genuinely good at, say, parsing messy invoices or doing a legal redline, my options are reading blog posts or DMing founders. There's nothing like npm or RapidAPI for agentic work. Plenty exists for tools, nothing for the work itself. Third, the pricing model feels off. Per-token billing has nothing to do with what the buyer actually cares about. "Review this contract" is a unit of work. "3.2 million tokens" isn't. Fourth, there's no good way to tell if Agent A is actually better than Agent B at a given task without paying to find out. Every vendor claims they're great. No shared evals. Our hypothesis is that a marketplace where work is sold as actual units (per task, per outcome, per SLA), with shared eval harnesses and standardized I/O, would chip away at all four. A few questions we'd love thoughts on: Which of those four hits closest to home, and which feels overblown? Anything we're missing? We have a feeling orchestration and state handoff between agents is bigger than we're giving it credit for, but we're not sure. If you've tried building on top of someone else's agent and given up, what was the moment you decided to do it yourself instead? Happy to go deeper in the thread or in DMs.
