Agentic Commerce

What Is Agentic Commerce?

Agentic commerce is the economy of AI agents transacting autonomously — holding their own wallets, paying per request, operating without human approval at each step.

It's being built on open protocols like x402 and MPP, settled in USDC on Solana, and projected by McKinsey to reach $3–5 trillion in transaction volume by 2030. This primer covers what's happening, why it's happening now, and what it means for anyone building services for machines.

x402 vs MPP: Comparing Agentic Payment Protocols

Two open standards dominate agent payment rails: x402, created by Coinbase and governed under the Linux Foundation, and MPP, co-developed by Stripe and Tempo.

Both solve the same problem — enabling agents to pay for services autonomously — but take different approaches. This guide compares them across payment model, settlement, fiat support, and compatibility, and explains why DocketLayer runs x402 natively while remaining compatible with MPP.

The Headless Merchant: Building for Agents, Not Humans

In March 2026, a16z crypto partner Noah Levine coined "headless merchant" to describe businesses built specifically for AI agents as customers.

A headless merchant has no storefront, no checkout page, no user accounts, no sales team — just a server, a set of endpoints, a price per call, and documentation.

This article explains why this category exists, how agents evaluate services differently from humans, and what it means for everything from distribution to customer relationships. DocketLayer is a headless merchant.

The History of HTTP 402

HTTP status code 402 — "Payment Required" — was defined in the original HTTP/1.1 specification in 1996 and reserved for future use.

It sat unused for nearly three decades because the payment infrastructure required to implement it simply didn't exist at web scale.

This article traces how 402 was defined, why it was never used, how blockchain settlement changed the economics, and how x402 finally implements what the 1996 RFC anticipated.

The Intention Economy

Fintech analyst Simon Taylor coined "the intention economy" to describe the emerging agent commerce model.

An agent doesn't browse, discover, or get persuaded — it arrives with intent already formed and needs only to transact.

This article explains the shift from attention to intention, what it means for how services are built and distributed, and why persuasion, discovery, and upsell become irrelevant when the buyer is a machine.

Legal Data as an Agentic Vertical

Not every data service fits the agent-native, pay-per-query model. The verticals that work best share a set of characteristics: the query is precisely defined, the value per call is clear, the data is structured, freshness matters, the source is fragmented, and the workflow is automatable end-to-end.

Federal court docket monitoring meets all six criteria.

This article explains why legal data is one of the clearest natural fits for agentic commerce, and why it's defensible in ways most data verticals are not.

How to Build a Walleted Docket Monitoring Agent

A walleted agent is an AI program that holds its own funds and pays for services autonomously.

This guide walks through building one end-to-end: a docket monitoring agent built with LangChain, a Solana wallet funded with USDC, x402 integration for automatic payment, and an alerting layer that emails you when something changes.

By the end, you have an always-on agent checking federal cases at $0.99 per query and surfacing only the exceptions.

How to Fund an Agent Wallet with USDC

Before an agent can make its first paid request, its wallet needs a USDC balance.

This guide covers every practical way to fund a Solana agent wallet — buying on Coinbase or Kraken, swapping via Jupiter, bridging from other chains — plus how much to fund for a given query volume, how to monitor the balance, and the most common failure mode: sending USDC on the wrong network.

x402 and Solana Wallet Setup

DocketLayer uses the x402 payment protocol. When your agent calls an endpoint, it includes a payment header containing $0.99 in USDC on Solana — no API keys, no accounts, no subscriptions.

The payment is the authentication.

This guide covers the three steps to get there: creating a Solana wallet (programmatic or Phantom), funding it with USDC, and configuring x402 in your agent code so it handles the 402 challenge, the payment, and the retry automatically.
