stats

What this deployment holds: collections, sources, items, items added today, feeds.

list_collections

The collections (niches) with their source, feed and item counts.

list_adapters

Every adapter this deployment can run, with the config fields each takes. Use before add_source.

list_enrichers

Every enricher (YouTube videos, Wikipedia, repo stats, downloads, company profiles, TL;DRs) and which collections turn it on by default. Items carry their results under `enrichment`.

list_sources

Sources with status, last run and item counts. Optionally one collection.

list_feeds

Public feeds, most followed first. Optionally one collection.

feed_items

What a feed selects, newest first. Page with before_id.

recent_items

Newest items, optionally narrowed to a collection, source or kind.

upcoming

Items dated in the future (releases, launches, deadlines), soonest first.

search_items

Full-text search over titles, summaries and tags. Use this first when you know a name.

match_items

Which title, channel or fixture is this name? Give a file name, a release name or a playlist entry ("Top.Gun.Maverick.2022.1080p.mkv", "US: ESPN2 HD"); it is cleaned (year, season and episode, quality…

where_to_buy_book

Where to buy a book. Give an `isbn` (10 or 13 digits, hyphens fine), or a `title` and `author`, or `item` (a books-collection item id). Answers with the edition from Open Library (title, authors, publ…

create_feed

Save a query as a feed (needs a key). Sources, kinds and tags narrow; q is a text match; upcoming keeps only future-dated items.

follow_feed

Follow a feed as the key owner (needs a key). Channels: webpush, email, webhook.

list_webhooks

The key owner's account webhook endpoints (never their secrets) and the event types this site emits. Needs a key.

Add an account webhook: signed POSTs (Standard Webhooks + CloudEvents) to an https URL for events such as feed.item.published (new items in feeds you follow), feed.followed, feed.created, submission.a…

update_webhook

Change an account webhook: url, events, description, or enabled (true turns it back on and clears its failure count). Needs a key.

delete_webhook

Remove an account webhook and its delivery log. Needs a key.

Recent webhook deliveries with status, attempts, last error and payload: for one endpoint, or all of yours. Needs a key.

submit_feed

Suggest an RSS or Atom feed for the index. No key needed. An admin reviews every suggestion before anything is fetched; approved podcast feeds are handed to rssamplifier, everything else becomes a sou…

find_profile_by_linkedin

The public profile a LinkedIn profile or company URL belongs to (linkedin.com/in/… or /company/…), or null. LinkedIn only: profiles are never looked up by email.

One person by id, `<slug>-<id>` or handle: the parsed view and the OpenProfile.md as served.

The key owner's invites: how many are left of the quota, and each invite with its status (open, used, expired, revoked). Needs a key.
