Sam Ragsdale argues in this essay that true agentic commerce will be open and permissionless, built on simple protocols, rather than closed platforms like ACP (OpenAI/Stripe) and UCP (Google), which he sees as the equivalent of AOL in the 90s — a walled garden with better UX, but a dead end for innovation.
The article builds its argument on a detailed historical parallel. In the 90s, two visions of the internet competed: AOL (curated content, flat pricing) versus open protocols (HTTP, DNS, HTML, Mosaic). AOL seemed to have won with its $350 billion Time Warner merger, but open protocols ultimately enabled the emergence of Facebook, Google, and Amazon — innovations that came from the edges, without permission from gatekeepers.
The internet's economic model was built on a hack: advertising. In 1997, Tim Berners-Lee created the HTTP 402 (Payment Required) code to enable micropayments, but fixed credit card fees made one-cent transactions impossible. Google worked around the problem by monetizing attention via advertisers. But AI agents fundamentally change this equation: they are not distractible. StackOverflow has lost 75% of its views since GPT-4, and tech site traffic has dropped 60%. Even walled gardens like Facebook and TikTok are now being breached by computer-use agents that perfectly mimic human behavior.
The solution lies in two emerging protocols: x402 (Coinbase) and mpp (Tempo + Stripe). Twenty-eight years after the invention of the 402 code, stablecoins on modern blockchains offer sub-cent transaction costs, finally solving the micropayments problem. These protocols allow agents to pay for any service — data, hosting, communication — without a prior commercial agreement, without a BD process, without a whitelist.
Ragsdale presents AgentCash as the missing discovery layer: a single balance giving access to all APIs, with merchant registries (x402scan.com, mppscan.com) where services register to be found by the 2,000+ agents already active. He sees skills as a transitional artifact, since modern agents (Claude 4.5+, Codex 5.2+) can discover an unfamiliar API, read its schema, and use it correctly without prior training.
The ultimate vision is one of hundreds of millions of agents accessing hundreds of thousands of services autonomously, recreating the permissionless innovation dynamic that made the open web great.
