| Tool | What it does | Hint |
|---|---|---|
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… | |
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… | |
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… | |
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… | |
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`, `identity` (key: value, null removes), `sections` (name: body, `none`… | |
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… | |
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… |
