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.

Security

Grade A, and why

bc-headless 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 1mo 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.

Headless Architecture

What Headless Means for BigCommerce

Decouple the frontend from BigCommerce:

  • BigCommerce serves as the commerce backend — catalog, orders, customers, payments
  • Your custom frontend handles presentation — React, Next.js, Vue, etc.
  • Communication via APIs — GraphQL Storefront API and REST API
  • Checkout via Embedded Checkout or Custom Checkout (Checkout API + Payments API)

Why Headless

  • Full frontend control (design, UX, performance)
  • Use modern frameworks (Next.js, Remix, Astro)
  • Composable architecture — mix BigCommerce with CMS, search, etc.
  • Better performance with SSR/SSG/ISR
  • Multi-channel frontend from single BigCommerce backend

Catalyst

What It Is

BigCommerce's official Next.js reference storefront:

  • Built on Next.js 14+ with App Router
  • Uses GraphQL Storefront API for data
  • Tailwind CSS for styling
  • Full-featured: PLP, PDP, cart, checkout, customer account, search
  • Designed as a starting point to fork and customize

Getting Started

npx create-catalyst-storefront@latest my-store

Prompts for:

  • BigCommerce store URL
  • Channel ID
  • Storefront API token

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.
