The essay discusses the resurgence of the previously neglected HTTP 402 code, initially intended for micro-payments, in the modern context of AI applications. It highlights how the demand for rapid, low-cost transactions driven by AI makes HTTP 402 relevant, paving the way for a revamped digital economy with seamless, automated exchanges.

Abstract generation in progress

Artificial intelligence awakens a forgotten Internet protocol from decades ago. The HTTP 402 code, created in 1996 to facilitate low-value transactions, is making a comeback in the current context of AI-powered applications, according to MetaEra’s analysis.

Why HTTP 402 Failed in the Past

Although initially designed for micro-payments, HTTP 402 never took off in the 1990s. The obstacles were significant: prohibitive transaction fees and insufficient network infrastructure to handle large-scale, high-frequency value exchanges. The technological and economic context of the time simply made fine-grained monetization impractical.

The Turning Point: AI Creates New Demand

The game changes dramatically with the rise of artificial intelligence. AI models generate fundamentally different needs: constant API calls, instant machine-to-machine transactions, and continuous settlements at minimal cost. These high-frequency, low-value transactional flows suddenly make HTTP 402 relevant and necessary.

Initiatives like AIsa focus on developing the essential ecosystem to operate HTTP 402 at scale. This includes specialized wallet solutions and ultra-fast settlement layers capable of processing millions of micropayments in parallel.

A Transformation of the Digital Economy in Sight

This dynamic sketches a future where HTTP 402 becomes the standard for automated exchanges in the AI economy. Transactions would occur seamlessly, in real-time, without human intervention. A complete overhaul of how value circulates within decentralized and autonomous digital systems.
