A command-line way to work with Shopify stores through their Admin and Storefront GraphQL APIs. Shopify is an e-commerce platform; the Admin API manages store data, while the Storefront API reads customer-facing shop data.

It is for listing products, managing inventory, retrieving orders, updating customers, reading custom fields, and querying products, collections, and carts.

It lets developers query and update store data directly without adding a software development kit or building a full app framework. This is useful for automating store operations from scripts.

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	$0.00015	$0.03915
Opus 5	$0.00008	$0.01958
Sonnet 5	$0.00003	$0.00783
Haiku 4.5	$0.00002	$0.00392

Security

Grade A, and why

shopify 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.

Shopify — Admin & Storefront GraphQL APIs

Work with Shopify stores directly through curl: list products, manage inventory, pull orders, update customers, read metafields. No SDK, no app framework — just the GraphQL endpoint and a custom-app access token.

The REST Admin API is legacy since 2024-04 and only receives security fixes. Use GraphQL Admin for all admin work. Use Storefront GraphQL for read-only customer-facing queries (products, collections, cart).

Prerequisites

In Shopify admin: Settings → Apps and sales channels → Develop apps → Create an app.
Click Configure Admin API scopes, select what you need (examples below), save.
Install app → the Admin API access token appears ONCE. Copy it immediately — Shopify will never show it again. Tokens start with shpat_.

Save to ${HERMES_HOME:-~/.hermes}/.env:

SHOPIFY_ACCESS_TOKEN=shpat_xxxxxxxxxxxxxxxxxxxx
SHOPIFY_STORE_DOMAIN=my-store.myshopify.com
SHOPIFY_API_VERSION=2026-01

Heads up: As of January 1, 2026, new "legacy custom apps" created in the Shopify admin are gone. New setups should use the Dev Dashboard (shopify.dev/docs/apps/build/dev-dashboard). Existing admin-created apps keep working. If the user's shop has no existing custom app and it's after 2026-01-01, direct them to Dev Dashboard instead of the admin flow.

Common scopes by task:

Products / collections: read_products, write_products
Inventory: read_inventory, write_inventory, read_locations
Orders: read_orders, write_orders (30 most recent without read_all_orders)
Customers: read_customers, write_customers
Draft orders: read_draft_orders, write_draft_orders
Fulfillments: read_fulfillments, write_fulfillments
Metafields / metaobjects: covered by the matching resource scopes

API Basics

Endpoint: https://$SHOPIFY_STORE_DOMAIN/admin/api/$SHOPIFY_API_VERSION/graphql.json
Auth header: X-Shopify-Access-Token: $SHOPIFY_ACCESS_TOKEN (NOT Authorization: Bearer)
Method: always POST, always Content-Type: application/json, body is {"query": "...", "variables": {...}}
HTTP 200 does not mean success. GraphQL returns errors in a top-level errors array and per-field userErrors. Always check both.
IDs are GID strings: gid://shopify/Product/10079467700516, gid://shopify/Variant/..., gid://shopify/Order/.... Pass these verbatim — don't strip the prefix.
Rate limit: calculated via query cost (leaky bucket). Each response has extensions.cost with requestedQueryCost, actualQueryCost, throttleStatus.{currentlyAvailable, maximumAvailable, restoreRate}. Back off when currentlyAvailable drops below your next query's cost. Standard shops = 100 points bucket, 50/s restore; Plus = 1000/100.

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.

Use this when the user asks whether a local listing is a scam, "too good to be true," worth looking at, or a good deal. Also use this when he asks you to find options — search/discover candidates, then vet the best ones. The goal is not a generic buying guide; it is a practical risk read with clear next steps.
