x402 and MPP agentic payment protocols enable micropayments for any web resource using Stellar's infrastructure, unlocking new revenue models for AI agents and humans across APIs, data feeds, content, and services without subscription friction.
x402 and MPP are HTTP-based payment protocols backed by Coinbase and Stripe that enable micropayments for web resources, designed primarily for AI agents but also applicable to humans. Built on established infrastructure like Stellar, they solve the problem of agents needing runtime payment capability without pre-configured billing. Use cases span AI inference, financial data, security scanning, web scraping, real-time data feeds, blockchain indexing, compute rental, and agent-to-agent transactions. For humans, micropayments enable new models for news, premium search, financial analysis, gaming, and IoT services. Stellar's relayer eliminates transaction fees while MPP batching improves latency, making the economics viable for high-frequency use cases and creating a third payment model beyond free-with-ads or subscription.
