x402 Readiness & Strategy
InvestmentBy Consultation
A structured review of whether machine-paid access fits your business, what you could realistically sell, and what becoming x402-ready would involve.
X402 · MACHINE-PAYABLE ACCESS
Sell to AI Agents with x402
x402 is an open payment standard that lets AI agents pay for access to your website, API, or service on the spot. Learn how it works with a self-serve guide, or have StorefrontSignal plan and build your x402 offer for you.
-
What it is
x402 lets AI agents and software pay for access to a website, API, or service automatically — no accounts, invoices, or manual checkout.
-
Why it matters
Agents are becoming buyers. Businesses that are x402-ready can earn from machine traffic instead of blocking it.
-
How to start
Learn the model with a guide, build it yourself or have StorefrontSignal implement it, then list it on x402Mall where humans and AI agents can find it.
