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 tags, playlist decorations) and matched by similarity. A matchup ("NFL: Chiefs vs Bills", "Lakers @ Celtics", "Rangers at Celtic 19:45") is answered by the fixture whose two teams those are, kicking

get_item

One item with its full adapter payload.

population

Population and demography, drilled down from the world to the ZIP code. Give a `key` (us, us-ca, us-ca-los-angeles, gb, gb-england-london), a US `zip`, or a place name in `q`; no argument is the world. Answers with the area (population, year, measures: age, income, home value, rent, poverty, education, unemployment, race and Hispanic origin for the US; growth, age structure, births, deaths, fertil

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.

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 source here.

search_profiles

People: one entry per person assembled from every app that serves their OpenProfile.md (podcasters from p0dcasters, public profiles from OutreachGraph). Search by name, headline or anything in the document; newest change first. Each answer carries the page, the openprofile.md URL, accounts, topics, Broadcast shows, the Guest section, and the job title, company and seniority the person published (f

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.

get_profile

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

claim_profile

Claim a profile as the key owner (needs a key). Proven when the key owner’s email is one the profile lists, or when the person’s site or show page links back to the profile’s nichedb page. An admin may claim on behalf of an email.

update_profile

Edit a profile you own (needs a key). Send `markdown`, a whole OpenProfile.md that replaces what you wrote before, or any of `name`, `headline`, `emoji`, `pronouns`, `web`, `identity` (key: value, null removes), `sections` (name: body, `none` removes), `handle`, `public`. What you write wins over every source and survives every re-read.

add_source

Add a source: an adapter with a config, fetched on a schedule (needs a key; admins and Pro). Call list_adapters first for the fields.

run_source

Fetch a source now instead of waiting for its schedule (needs a key; owner or admin).

search_tlds

Top-level domains: every label in IANA's root, with type, registry, RDAP server and each registrar's one-year register/renew/transfer price (Porkbun, Dynadot, Cloudflare, OVHcloud). Sorted by renewal by default, because the first year is a promotion. `best` is the cheapest USD price across registrars; with `registrar` it is that registrar's own price in its currency. Answers carry facet counts. `t

get_tld

One top-level domain: type, registry, RDAP server, when it entered or left the root, every registrar price (register, renew, transfer, restore, promotions, privacy, restrictions) and its change history.

tld_changes

Top-level domains added to or removed from IANA's root, newest first, with the IANA list version each happened in. Nobody else publishes this diff.

check_domain

Is a domain name registered? Asks each registry over RDAP. Give `name` as a full name (foo.watches), or a bare word with `tlds` (foo + com,dev,io), or several names comma separated. Each answer is registered (with registrar and expiry), not_registered, or unknown. not_registered means the registry holds no registration; the name may still be reserved or premium, so it is not a promise that it is f
