For a skill, the `SKILL.md` URL is enough; the rest is checked. **Validates before charging:** a refused body (400) and an exhausted quota (429) come BEFORE the 402, so no payment settles for a listing already known not to get in.

 ⟨16 unchanged words⟩  question a reader or an agent actually asks. Find feeds by text, format, language and availability. Filter and text search run in the SAME full-text query: values inside one parameter are OR'd, different parameters are AND'd. Without `q` the order is by newest in the index (`recentes`) and `next_cursor` is a keyset — follow `next` to walk everything. With `q` the order is relevance and paging is by `offset`. We index and link; the feeds belong to whoever publishes them.

 ⟨23 unchanged words⟩  `ord` comes from feed_posts; 0 is the newest. Two bodies for the same post, both produced when we READ the feed, never at request time: `conteudo_html` keeps the author's formatting through an allowlist (only known tags and attributes survive; script, style, iframe and event handlers are dropped with their content), and `conteudo` is the same text as Markdown — the shape an agent usually wants. Neither can carry script. 404 when the feed or the position is unknown.

 ⟨36 unchanged words⟩ an id from this index, never a URL. Up to 40 posts, in the order the feed publishes them, WITHOUT the body — the body of one post comes from `/items/:ord`.

Empty list when the feed has not been read yet.

One listing's page. The owner sees their own even when pending or hidden.

Same visibility as the listing page. Call it only when the listing page carries `readme_api`: a page without it has no README collected, and this route answers 404.

Comments on a live listing. With a credential on the call, each comment of yours comes with `mine: true`.

 ⟨5 unchanged words⟩  servers, skills, plugins and OKF knowledge bundles. `live` listings first and the `low` tail (few stars or no clear license) after them in every order — `low=0` leaves the tail out. To walk everything, follow `next`: without `q` it is a cursor (`next_cursor`, keyset on the order's index) and has no ceiling; every listing also has an HTML page at `/l/:id` and the shards of `/sitemap-listings.xml` list them all. `q` runs on a full-text index (FTS5, bm25) kept in the same transaction as every text write. With `q` and `low=0`, `low_count` says how many `low` listings the filter left out — LIKE with a cap of 200. The query is mapped onto kind/topic/transport filters unless `interpret=0`.

MCP subregistry (GET /v0.1/servers). Only live kind=mcp. Only `kind=mcp` and only `live`. It is the route a generic MCP client knows how to read without knowing this product. `GET /v0/servers` is an alias of the same resource, kept for whoever already pointed there — this is the canonical URL.

An empty list means no change since the series began — the listing still exists. Stale means no push for 12 months. Reading this endpoint does not refresh the record.

 ⟨18 unchanged words⟩  create_listing. No credential; only the decision comes back. Every submission is born `pending` and a person approves it by hand; this is the receipt you poll after `POST /api/listings` (its response carries this URL as `status_api`). Only the decision comes back, never the unreviewed content: the id (`lst_…`, unguessable) is all it takes, and the page itself keeps its rule — owner only until it is public. Answers are cached for 60 s per point of presence: poll every few minutes, not every second.

 ⟨8 unchanged words⟩ this catalog does not list yet (casou=0). Newest change first. `casou=0` is what the indexes know and the catalog does not — the list to look at before submitting a server. Filters are AND'd.

 ⟨27 unchanged words⟩  with its license. Take the id from list_listings. A signal belongs to a listing only when it is the SAME object: the name in the official MCP registry, the exact remote endpoint URL or the GitHub `owner/repo`, in that order. A shared domain never matches — two servers on one host are different products. Up to 20 signals, one per index and record.

 ⟨26 unchanged words⟩  count; search root concept text. Paginate with limit/offset. Only `live` bundles. Free text matches the name, the tagline, the description and the origin identifier (`owner/repo:path` or the bundle URL). No `total` on purpose: `GET /api/okf/stats` has it.

 ⟨25 unchanged words⟩  checked by the collector before anything is read. No account, no payment: ownership is proved by a key file on the host, exactly as IndexNow does it. Host `https://<host>/<key>.txt` containing the key (or point `keyLocation` at another path on the SAME host), then send the bundle URLs. We answer **202**: the key has not been checked yet. Verification and reading happen on our collector, never at the edge — so nothing is published, and no URL of yours is fetched, before the key matches. Re-sending a URL is how you say the bundle changed; it goes back in line to be re-read. At most 100 URLs per request and 200 per host per UTC day. The same queue is served by `POST https://okfindex.com/api/ping`, the index's own home — search, bundle cards and statistics live there.
