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

bestbuy-checkout scanned grade A with 1 finding 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Best Buy Checkout

Buy, track, and return products from Best Buy (bestbuy.com) through the Zinc API (https://api.zinc.com). US orders.

Powered by Zinc Universal Checkout. The same API buys from Best Buy and almost any other US retailer. To order across multiple retailers from one skill, install the universal-checkout skill (npx skills add zincio/skills --skill universal-checkout). Live retailer list: GET https://api.zinc.com/retailers.

Getting started

Four steps, in order. Full walkthrough: Agent Sandbox Quickstart and Going Live.

  1. Get a test key. POST https://api.zinc.com/sandbox/keys — no auth, no signup. Returns api_key (zn_test_…) and a ready-made example_order. Send it as Authorization: Bearer <api_key> from here on.
  2. Place a test order. POST /orders with that example_order, then poll GET /orders/{id}. Free. status reaches order_placed — that is success, and it never becomes delivered; shipping shows up under tracking_numbers[0].status.
  3. Earn your live key. POST /device/code with your test key as Bearer — that is what carries your sandbox history over. Show your operator the link it returns, then poll POST /device/token (no Authorization header; 400 authorization_pending means keep waiting). On approval you get a zn_live_ key once, plus a $5 starter credit in their wallet.
  4. Buy something real. POST /orders with a bestbuy.com product URL. max_price is a ceiling, not a price — you are charged the retailer's actual total, so set it a little above the listed price to leave room for tax and shipping. Ask your operator for the shipping address (phone_number is required) and confirm the item and price with them first.

Watch the money: GET /wallet/me shows the balance and order_fee_cents (charged per order, on top of max_price). Each /search call costs 1¢ from the same wallet.

Changes

What this file has done since we first saw it

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.
