A starting point for building a custom online game shop with Xsolla services. It connects player login, product and order management, and payment screens that can appear inside the site's own pages.

Use it to scope and build a complete game store covering player identity, catalogs, carts, orders, promotions, inventory, virtual currency, and checkout.

It organizes several separate commerce services into one planned storefront, so the shop can use the partner's frontend while Xsolla handles backend commerce and payments.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add xsolla/xsolla-ai-kit --skill shop-setup

Clone the repo

git clone --depth 1 https://github.com/xsolla/xsolla-ai-kit

Made for: Claude Code, Cursor.

Or install xsolla-ai-kit, the plugin that ships this one along with the rest of its 13 skills, 1 MCP server.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00099	$0.02975
Opus 5.5	$0.00040	$0.01190
Sonnet 5.5	$0.00020	$0.00595
Haiku 4.5	$0.00010	$0.00298

Security

Grade A, and why

shop-setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Xsolla Headless Shop — Architecture Overview

If the user does not want to write, review, and deploy the shop code, stop and open nocode-shop-setup. If the user has not said which they want, show Shop building paths in AGENTS.md and ask.

What is Headless Shop

A custom game store assembled from individual Xsolla products and integrated into the partner's own site with the help of AI. The partner writes the frontend; Xsolla provides backend services and SDKs.

Four components:

Component	Role
Login	Player identity — authentication, JWT, social login, game ID binding
Store API	Commerce backend — catalog, cart, orders, promos, inventory, virtual currency
Headless Checkout SDK ⭐	Embedded payment UI on the partner's site — recommended for Headless Store
Pay Station	Xsolla-hosted payment page — fallback when embedded UI is not needed

Headless Checkout SDK (github.com/xsolla/pay-station-sdk) is the recommended payment layer for this integration type. It renders the full payment UI directly on the partner's site without redirecting the player elsewhere — the natural fit when AI is already building the entire storefront. Pay Station redirect is a valid fallback but not the default choice here.

System Interaction (logical, not code)

Partner's site
│
├── Store API ──────────────────── catalog, cart, orders, promos, inventory
│       │
│       └── Login (JWT) ────────── authenticated cart, user balance, personal limits
│
└── Headless Checkout SDK ──────── embedded payment UI on partner's site
        │
        └── Webhook ────────────── partner's backend ← fulfillment trigger

Data flow for a purchase:

Player browses catalog → Store API (no auth required)
Player adds to cart → Store API (guest or JWT)
Player logs in → Login issues JWT → cart switches to Bearer mode
Checkout: Store API creates payment token → Headless Checkout SDK (or Pay Station) handles payment
Payment confirmed → Xsolla sends webhook to partner's backend → partner grants item in game

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
