Agentic commerce is here. ACP & UCP promise checkout in ChatGPT & Gemini. Soon hundreds of millions of consumers around the globe will find better products, merchants will have improved conversion rates, and platforms will be able to take 5-10%. But checkout in ChatGPT is an incremental improvement. It will not reshape society as the internet did in the early 2000s. Open Agentic Commerce will.

We must go back to the '90s to understand why.

There were two different competing versions of 'the internet' at the time.

• AOL's: One price, mail, weather, additional approved content, and eventually the whole Time Warner content library.
• Open protocols: HTTP, DNS, HTML, and a browser called Mosaic

Mosaic looked completely ridiculous compared to the first. There were so few sites on Mosaic's internet that there was no need for search, an alphabetical index was sufficient.^[1] 8 years later, AOL merged with Time Warner in a $350B merger of equals. The market had decided. The curated content bundle was the path forward.

But it was not too long until Mosaic and the open protocols won, and human civilization stepped forward into the digital age.

Why? Consider if walled gardens had won.

Mark Zuckerberg wants to start The Facebook in 2004. He needs a distribution deal with AOL. Two kids at Stanford want to index the web, they need CompuServe's permission. A guy wants to sell books online from his garage, he needs to pitch MSN's content team.

“Go back to school little boys”, they say. None of it happens. The entire digital economy we take for granted simply doesn't exist.

Open protocols meant no gatekeepers. Anyone with a server and a domain name could reach the entire internet. The edges innovated, the center couldn't keep up, and the result was the largest wealth creation event in human history. It's a fundamental principle of capitalism: innovation comes from the edges.

Back to 1997: Tim Berners Lee, Marc Andreessen & co were working on the protocols and the browser. At the time, running a server cost hundreds of thousands of dollars. It was not obvious why a content server would respond to an unknown consumer. It would be expensive to do so, and there was no known financial incentive.^[2]

They created a message called '402' that a server could send to a consumer: this content is available, for a small fee. But there was no sensible way to pay digitally. Paypal did not yet exist, and credit cards had fixed fees in the tens-of-cents, far too high for 1-cent micro-transactions.

But the web took off anyway.

Google figured out an odd business model for the internet: ads.^[8] In historical media the primary economic relationship is between the content producer and the consumer. Building on the economics of broadcast, Google helped introduce a third party, the advertiser, to pay for the relationship between the producer and consumer.

Ingenious. Now producers could monetize the attention of the viewer. No need for any prior relationship with the consumer. Google sat in the money flow, between the advertiser and content producer, charging whatever take rates they wanted.^[3]

So the need for micropayments was averted. Open source software got off the ground, the cloud revolution happened, hosting costs plummeted 100x. Google became the biggest proponent of the free and open internet. The more consumers searched, the more money Google made. So they invested hundreds of billions to make the internet fast, cheap and ubiquitous.

And then in the 2010s, nothing happened.^[4]

Interest rates were low, technology changed slowly, the walled gardens fed their troops and gathered strength.

In 2022, ChatGPT launched, and the world was set to change again. LLMs could do more than deliver results, they could generate and compile many such results into a handy summary, often without touching the content itself.^[5]

By GPT-4, it was clear agents were the next step: LLMs adept at using computers like humans, only cheaper and more effective.

And just like that, the economics of the internet changed.

The business model from 1997 to 2024 was distraction. Humans reading a webpage can be distracted by an advert, monetizing their partial attention. LLMs / Agents do not get distracted.

StackOverflow views are down 75% since GPT-4, Tech news traffic down 60% etc. Tech consumers are early adopters, but it's coming for all information on the web.^[6]

Checkout in ChatGPT doesn't matter. The internet is civilization's town square and the economic contract is now obsolete.

There are small pockets of the internet that have defended themselves from Google's reach, the proverbial walled gardens with truly differentiated content: Facebook, TikTok, LinkedIn. Which are resistant to bot automated scraping thanks to thousands of highly paid engineers working around the clock.

But walled garden defenses just broke too. Computer-use agents perfectly mimic the traffic of real human users. Snake oil salesmen will prescribe cures for the next 10 years, and Sand Hill Road will invest. But there are no cures. The walls of the fortress have been obsoleted by the warplane.

What's Next?

Open Agentic Commerce.

Checkout in ChatGPT is the AOL of agentic commerce. It's a curated catalog, a walled garden with better UX. To sell through it, merchants need months of BD, stringent legal docs, concrete 5-year plans, revenue, a strong user-base, and a story that will make shareholders happy when it appears on the front page of the NYT.

Open Agentic Commerce is the HTTP of today. A simple set of protocols that let agents pay for anything they need. Data, cloud hosting, communication and plenty of things we haven't dreamed up yet.

The two front-runners are x402 from Coinbase and mpp from Tempo + Stripe. 28-years after the '402' status code was invented, we have a viable implementation. Stablecoins on modern blockchains have sub-cent fixed transaction costs, solving the exact fixed-fee problem that killed micropayments in 1997.

There's no BD, no whitelist, just simple permissionless standards.

These protocols focus on exactly two things:

• Agents: “how do I send money?”
• Merchants: “how can I be sure this agent paid?”

LLMs are good at calling tools they've never seen before. Starting with the Claude 4.5+ models and the Codex 5.2+ models, agents can discover an API, read its schema, and use it correctly, without any prior training.

The current discourse focuses on “skills”. Think of them as natural language programs, which can be composed as building blocks. A non-technical founder can write a Slack message and have it execute as software:

1. Buy pizza from the closest place with good reviews, track status every 10 minutes (PIZZA_SKILL.md)
2. When the driver is 5 minutes away, turn on the porch light (HUE_LIGHT_SKILL.md)
3. If delivered in under 30 minutes, send the driver a $5 tip (COURIER_SKILL.md)

No code, no computer science degree. The agent reads the intent, writes a computer-native program just in time, executes it, and throws it away. Programming as a discipline is optional, literacy in human native language is sufficient.

Skills work. But they're a transitional artifact, the first obvious thing to build once we discovered agents could call unfamiliar tools. They require someone to write, publish, security screen, and update them. And the agent needs them loaded in advance. It's messy.

The skill discourse hides a deeper unlock: agents can compose capabilities like never before.

Pizza is a toy example. Here's a real one: An agent managing a small business's supply chain notices a packaging supplier's prices have crept up 15% due to tariffs. It discovers three local alternatives, requests samples from each, negotiates volume pricing, and switches. All before the owner's morning workout.

No API partnership, procurement team, or RFP process. Just an agent with a balance and open protocols.

Discovery

Agents can pay, agents can compose, but they can't yet find what they need.

What remains is discovery. For an agent: “how do I find stuff to buy?”, for a merchant: “how do I tell agents about my services?”.

Enter AgentCash. It's a single balance, access to every API on the internet. When an agent gets blocked, it can reach for thousands of APIs, spend pennies, and proceed.

Critically, AgentCash bundles payment and merchant discovery. Merchants can register their servers on x402scan.com or mppscan.com and instantly be exposed to all 2,000+ AgentCash agents.^[7] In a few years hundreds of millions of agents will access hundreds of thousands of services, fully autonomously.

In 1997, the web had no business model and no one knew why a server would talk to a stranger. Open protocols and a clever hack called advertising figured it out, and civilization went digital. In 2026, that hack is dying. Open protocols and a 28-year-old status code are about to replace it.

Welcome to the age of Open Agentic Commerce.
