Seller Templates v1.1.0: One Config, Two Storefronts — Sell to AI Agents AND Humans

Most x402 tooling assumes you are a developer standing up a server. Most storefront tooling assumes your buyer is a human with a credit card. The agent economy has both buyers now — so Script Master Labs built the template that sells to both from a single config.

SML Seller Templates v1.1.0 are live: $149, one time. Product page: https://scriptmasterlabs.com/seller-templates

What you get

You fill in one config:

• payTo — your own wallet address. Payments go to you. There is no custody and no SML account holding your money.
• What you sell — one of three business types (below).
• Your price — in USDC.
• Optional human checkout link — if you also take cards somewhere, the human page can carry it.

From that one config, the template generates both:

1. An agent-facing x402 storefront — machines discover your offer, get a 402 quote, pay, and receive the goods, settled through OMNIGATE (SML's own x402 facilitator on Base/Arc).
2. A human storefront page — a normal page a person can read, with the same offer and price.

The pack includes a 13-page NEWBIE-GUIDE.pdf with real screenshots and a walkthrough video, because a template only a protocol engineer can run is not a product.

The full pack is open: https://gitlab.com/script-master-labs-llc-group/scriptmasterlabs-seller-templates

The three business types

1. Sell a file — a checklist, a dataset, a PDF, a zip. The buyer pays, the file is delivered.
2. Sell a pay-per-call API — your endpoint sits behind the x402 paywall; agents pay per call.
3. Sell paid MCP tools — your MCP server's tools are priced per invocation, so agent clients pay as they call.

How the 5% residual works — the honest mechanics

SML takes a 5% residual of the sale price, and the mechanics matter, so here they are without varnish:

• The 5% is charged on top of your price and disclosed in the 402 quote before the buyer signs. The seller always receives the full price.
• It is collected only when the payment travels through an SML-aware payer — a payer built to attach the fee leg (the kit's own payer does this).
• A stock x402 client cannot attach that non-standard leg. Those payments settle on OMNIGATE's standard terms instead: a flat 0.005 USDC facilitator leg when one is attached, and fee-less (waived) inside a budget of 500 settlements/day total and 100/day per seller (UTC); past the budget, the standard fee requirement resumes.
• There is no custody at any point. A guaranteed percentage skim from arbitrary stock clients is impossible without custody, and custody is a line we do not cross — so the copy says exactly what the code does.

Settlement proof — labeled SELF-PROOF

These are SELF-PROOF settlements: SML's own proof wallet paying SML's own proof store, run to prove the path end-to-end before asking anyone else to trust it. They are not outside-buyer revenue and are not presented as such.

• $1.00 sale — merchant received the full $1.00: tx 0x72636711…aeb85c. The 5% fee leg collected exactly $0.05: tx 0x72ba36e2…6549e7.
• $0.01 sale — merchant tx: 0x84c4cc6c…7054d0. The 5% leg collected exactly $0.0005 (500 atomic units): tx 0x4a675634…2c1f.

The live proof store is still up, selling a real $0.01 checklist file, with its receipts page public: https://seller-template-proof-seller.onrender.com
