New Features

Wish List and Pull List

The biggest addition this month is the launch of the Wish List and Pull List apps. Both lists are private to their owner, consistent with the existing User Collection, and are created automatically on first access — no setup required.

Pull List

The Pull List is the digital equivalent of a comic shop pull list: a collection of ongoing series you follow. It is accessible under /pull-list/ on the site and fully supported via the API at /api/pull_list/.

API endpoints:

Method	Endpoint	Description
GET	/api/pull_list/	Pull list metadata (series count, last modified)
GET	/api/pull_list/series/	Paginated list of series on the pull list
POST	/api/pull_list/series/add	Add a series ({"series_id": 123})
DELETE	/api/pull_list/series/{series_id}/remove	Remove a series
GET	/api/pull_list/issues/	Upcoming issues from pull list series

The /api/pull_list/issues/ endpoint is especially useful for building "what's coming out this week" views. It returns issues ordered by store date then series name, and accepts two optional date filters:

Parameter	Format	Description
store_date_after	YYYY-MM-DD	Issues on or after this store date
store_date_before	YYYY-MM-DD	Issues on or before this store date

Each issue in the response includes the series summary, issue number, cover date, store date, and cover image.

Adding a series is idempotent: posting a series_id that is already on the list returns 200 OK with the existing entry rather than an error.

Wish List

The Wish List tracks specific issues you want to acquire, with support for priority, condition goals, budget limits, and acquisition status. It lives at /wish-list/ on the site and is backed by the API at /api/wish_list/.

API endpoints:

Method	Endpoint	Description
GET	/api/wish_list/	Wish list metadata (item count, last modified)
GET	/api/wish_list/items/	Paginated list of items
POST	/api/wish_list/items/add	Add an issue to the wish list
POST	/api/wish_list/items/{item_id}/acquire	Mark an item as acquired
DELETE	/api/wish_list/items/{item_id}/remove	Remove an item

When adding an item, only issue_id is required. All other fields are optional:

{
  "issue_id": 5001,
  "priority": 1,
  "desired_grade": "6.0",
  "max_price": "500.00",
  "max_price_currency": "GBP",
  "notes": "First appearance of Spider-Man"
}

Priority defaults to 3 and max_price_currency defaults to USD if omitted. Like the pull list, adding an issue that is already on the wish list is idempotent — it returns 200 OK with the existing item.

Each item carries a status that moves through a simple lifecycle:

Status	Meaning
Wanted	Actively looking for this issue
Found	Located a copy, not yet purchased
Acquired	Purchased; a collection item has been created

The acquire endpoint is the key integration point between the Wish List and the User Collection. Posting to /api/wish_list/items/{item_id}/acquire with optional purchase details (date, price, currency, store, notes) marks the wish list item as Acquired and creates a corresponding CollectionItem. The response tells you whether the collection item was newly created or already existed:

{
  "wish_list_item_id": 42,
  "collection_item_id": 987,
  "created": true,
  "status": "Acquired"
}

The operation is idempotent: if the issue is already in the collection, the existing collection item is left untouched and created returns false.

A new version of Mokkari has been released that adds support for these new endpoints.

API Improvements

New Filter Parameters

Several new filter parameters have been added to the Issue and Series list endpoints, making it much easier to build targeted queries:

Filter	Issue endpoint	Series endpoint
creator_id	✓	✓
character_id	✓	✓
team_id	✓	✓
universe_id	✓	✓
imprint_id		✓
role_id	✓	✓

role_id supports multiple comma-separated values to filter by several roles at once.

year_end in Series List

The Series list endpoint now includes the year_end field, so clients can tell at a glance whether a series is ongoing or has concluded — without needing to fetch the full detail endpoint.

Dependency and Tooling Upgrades

• Python 3.14 — the project is now running on Python's latest release.
• Migrated from pipenv to uv — dependency management and the container build now use uv, with a multi-stage Containerfile that keeps the final image lean and CI caching keyed to the lockfile.
• Django 6.0.5 — upgraded from Django 5.x to the recently released Django 6 series.

Metron Software Wiki Page

We've added a dedicated Software page to the Metron wiki where developers can showcase projects built on the Metron API.

If you've built a tool, app, or library that uses Metron's data — whether it's a reading tracker, a pull list manager, a CLI tool, or anything else — this is the place to list it. The page is intended to help users discover what the community has built and to give developers a bit of visibility.

To get your project listed, simply edit the wiki page directly and add an entry for it.

OpenCollective

A huge thank you to everyone who has contributed to our Open Collective! Your support makes a real difference in keeping the Metron Project running and growing.

What Your Contributions Support

Funds from Open Collective go directly toward:

• Server hosting costs - Keeping the Metron website and API available
• Domain registration - Annual domain name renewals
• Future capacity increases - Scaling resources as the database and user base grows

All expenses are transparent and publicly viewable on our Open Collective page, so you can see exactly where every dollar goes.

Support the Project

Any donations to help maintain our current API rate limits and keep the service free are greatly appreciated. Contributions of any size help ensure Metron remains a free resource for the comic book community.

Anyway, that's everything for this month! Take care.
