Episode notes
Payments As A Native Internet Layer
- X402 is a simple open standard for transmitting payment intent between computers and agents.
- It enables agents to pay APIs, content, and services without bespoke integrations across vendors.
Standards That Work Together
- X402 complements other agent standards like MCP and A2A rather than replacing them.
- Use X402 for value transmission while other standards handle tool use and agent communication.
Instant Value Removes Human Bottlenecks
- Making value transfer instant removes human-in-the-loop bottlenecks for API access and composability.
- Agents can purchase small pieces of data or tool access on demand, enabling a fully composable machine economy.
