The real cost of an agent payment layer isn't the fee. It's the hours a developer loses when a payment fails and nobody can say why.

Kite is a good project to run that test on. Mainnet went live in April with Agent Passport and 90+ service providers already integrated, plus x402 and MCP support, a kpass CLI, and a testnet. For builders, the fully supported path today is MCP: agents like Cursor and Claude Desktop connect to Kite, and payments run inside a session with a spending limit.

What I like: the docs list real failure cases like expired sessions and insufficient budget, with fixes. What I'd watch: sessions expire, so "run it again tomorrow" means re-authenticating, and two of the three developer modes, the ones for programmatic setup, are still marked "coming soon." #KiteBBW

None of that is a red flag this early. It's just the gap between strong architecture and a smooth build.

So my test is simple: can an ordinary developer build an agent that pays for an API in one weekend, then run it again the next day without guessing?

If yes, developer experience becomes Kite's real edge. If not, great architecture stays a diagram.

Where do builders get stuck first?
