STELAR DIGITAL LLC · ROSEVILLE, CA

The agent-commerce company.Commerce is getting a second kind of customer. We build for it.

People now send AI agents to find things, compare things, and buy things. Every product this company ships answers the same question from a different side: when a machine tries to do business with you, does it work?

WHAT WE BUILD

Shopify apps

Four small tools that keep stores running — stock alerts, invoices, supplier orders, AI visibility.

4 LIVE

Machine payments

APIs that AI agents pay per call, in stablecoins — no account, no invoice, no human in the loop.

LIVE

The agent economy

Testing whether AI shoppers can actually buy from real stores — and showing owners the fix when they can't.

LAUNCHING
WHAT WE BUILD

Three product lines. Each has its own home — this page is the company behind them.

LAUNCHING

Can an AI buy from your store?

A real AI buying agent walks your store and reports exactly where it gets stuck — with the fix for each break. One store, one walk, one honest report.

Small tools that just run.

Boring problems, fixed for good — AI visibility, stock alerts, supplier orders, clean invoices. Flat prices that never scale against you.

LIVE

APIs machines pay per call.

Market-signal endpoints an agent can hit, pay in USDC over x402, and use — no account, no invoice. Plus x402 Doctor: the conformance report for anyone else selling this way.

HOW WE WORK

Built with AI,
signed by a human.

Flat means flat.

The price on the tin is the price. No per-order fees, no volume tiers, no surprise upgrade wall at your busiest month.

Graded against a versioned rubric.

Anything we grade is graded against a versioned rubric — the x402 Doctor rubric is published and dated; the store-audit rubric ships with its launch. Reports stay private to the store that ordered them — never pay-for-grade.

A real person answers.

Support goes to the person who signs off on the code. When something breaks, it gets fixed — not ticketed.

Sent when something actually ships.

A shipped app, a number that moved, a lesson that cost us. No cadence, no funnel, no spam.
