kronan-cli

CLI tool for shopping at Krónan.is, Iceland's grocery store chain. Uses the official Krónan Public API. Designed for both humans and AI agents.

Prerequisites

GitHub CLI (gh) — required for the install command
A Krónan account with Auðkenni (Icelandic e-ID) login
An Access Token from https://kronan.is/adgangur/adgangslyklar

Install

gh repo clone arnif/kronan-cli /tmp/kronan-cli && bash /tmp/kronan-cli/install.sh

What this does: clones the repo to /tmp/kronan-cli, then install.sh downloads a pre-built binary from the latest GitHub release and places it at ~/.local/bin/kronan (override with INSTALL_DIR).

To build from source instead:

gh repo clone arnif/kronan-cli && cd kronan-cli
bun install && bun build --compile src/index.ts --outfile kronan
mv kronan ~/.local/bin/

Security and privacy

Install script: install.sh executes on your machine and downloads a binary. Audit the repository and the script before running.
Token storage: Access tokens are stored at ~/.kronan/token. These are credentials for the Krónan Public API. Ensure the file is only readable by your user (chmod 600 ~/.kronan/token).
PII: kronan me outputs your identity information (name and type - user or customer group). Be careful when sharing this output.
API Access: Tokens are created in your Krónan account settings and can be revoked at any time at https://kronan.is/adgangur/adgangslyklar

Authentication

First, create an access token:

Go to https://kronan.is/adgangur/adgangslyklar
Log in with Auðkenni (Icelandic e-ID)
Create a new access token

Then save it with the CLI:

kronan token <your-access-token>

The token will be validated and saved locally.

kronan logout    # Clear stored token
kronan status    # Check authentication status

kronan stats --include-ignored                 # Include hidden products
kronan stats ignore <id>                       # Hide product from stats
kronan stats unignore <id>                     # Unhide product

User identity

kronan me              # Show current identity (user or customer group)
kronan me --json

AI Agent Usage

All commands support --json for structured output. This makes kronan-cli suitable as a tool for AI agents managing grocery shopping.

Important: Commands that change state can modify the user's real data. Agents must ask for explicit user confirmation before running any state-changing command.

State-changing commands:

cart add, cart clear
order delete-lines, order lower-quantity, order toggle-substitution
lists create, lists delete, lists add, lists remove, lists clear
notes add, notes update, notes remove, notes toggle, notes clear
stats ignore, stats unignore

Read-only commands are safe to run without confirmation:

search, product, categories, category
orders, order (view)
cart (view)
lists (view)
notes (view), notes archived
stats (view)
me, status

Example agent workflows

Build a weekly cart from frequently purchased items:

# 1. Get purchase statistics to find frequently bought items
kronan stats --limit 50 --json

# 2. Add top items to cart at their typical quantities
kronan cart add 100224198 6    # Nýmjólk x6
kronan cart add 02200946 1     # Heimilisbrauð

# 3. Review the cart
kronan cart --json

Create a shopping list for a recipe:

# 1. Create a new list
kronan lists create "Pizza Night" --description "Ingredients for homemade pizza"

# 2. Search for products and add to list
kronan search "mozzarella" --json
kronan lists add <list-token> 100246180 2

kronan search "pizzasósa" --json
kronan lists add <list-token> 100221958 1

# 3. View the completed list
kronan lists view <list-token>

Manage shopping with notes (Skundalisti):

# 1. Add items to shopping note
kronan notes add --text "Mjólk"
kronan notes add --sku 100224198 --quantity 2

# 2. Mark items as you shop
kronan notes toggle <line-token>

# 3. View remaining items
kronan notes

# 4. View completed items
kronan notes archived

Analyze and optimize purchases:

# View purchase frequency for all products
kronan stats --json

# Hide irrelevant products from stats
kronan stats ignore <id>
