Building Infrastructure for Agentic Commerce
As AI agents begin to act autonomously on behalf of users — browsing, purchasing, negotiating — the infrastructure beneath commerce needs to be rethought from first principles.
By Majilesh
The next wave of commerce won't be driven by humans tapping "buy now." It will be driven by agents — AI systems acting on behalf of users — that browse, evaluate, negotiate, and transact without a human in the loop.
This shift breaks almost every assumption our commerce infrastructure is built on.
Authentication assumes a human
OAuth, CAPTCHA, 2FA — these exist because we assume a person is on the other end. When an agent authenticates, it needs a different model: one based on capability proofs, delegation chains, and verifiable identity anchors rather than passwords and SMS codes.
Payments assume intent at the moment of transaction
Current payment flows confirm intent at the point of sale. With agents, intent is declared in advance — "buy the cheapest flight under $500 on Tuesday" — and the transaction happens later, possibly while you're asleep. The payment infrastructure needs to support pre-authorised, scoped, revocable mandates.
The x402 protocol is one interesting attempt here: a micropayments standard built for machine-to-machine HTTP transactions. It won't solve everything, but it points in the right direction.
What needs to be rebuilt
Three things need to change for agentic commerce to work at scale:
Agent identity. Agents need persistent, verifiable identities that carry reputation and delegation provenance. MCP (Model Context Protocol) is an emerging standard here.
Scoped authorisation. Users need to grant narrow, time-limited, revocable permissions — not hand over full account access.
Audit trails. Every agentic action needs a receipts layer. What did the agent do, on whose behalf, and based on what instruction?
We're still early. Most of this infrastructure doesn't exist yet. But the companies that build it — not the AI models themselves, but the rails underneath them — will be foundational to how the next decade of commerce works.
