x402 is a payment layer for the web: software pays for what it uses, request by request. It lets an AI agent buy data or compute on its own. Dev Office Hours with Thomas Kammerlocher (Thomas Kammerlocher):

@kammerlo91 AI agents paying per request is where low, predictable fees really matter. Thousands of tiny payments a day only work if each one costs next to nothing. Curious how close x402 on Cardano is to production.

@kammerlo91 This will work really well. Anyone builds on Cardano should definitely put some efforts into agentic payment

@kammerlo91 AI paying its own way

@kammerlo91 Robots paying robots, one request at a time 🤖💸 No subscription, no card on file. And on Cardano the fee is known before you send, which is exactly what a bot needs.

@kammerlo91 when software pays per request, value follows usage
