The corpus is rebuilt once a night; anything shorter is load without freshness.

Endpoints

6 calls, all GET
Every one is read-only, unauthenticated and cross-origin readable. The link on each row runs it.
EndpointWhat it answersTry it
/api/searchGETItem-level search across every indexed registry, ranked in Postgres and counted in the same pass. Omit q to browse the whole corpus. Nothing is re-sorted on the client — the order that comes back is the order to render.Run it
/api/items/{registry}/{name}GETOne component, with everything its page needs in a single call: install command, dependencies, files it writes, the access verdict, whether its registry permits framing, and its siblings.Run it
/api/registriesGETEvery registry the crawl reaches, one row each, with its inventory counts and its GitHub facts.Run it
/api/registries/{slug}GETOne registry plus its whole inventory, grouped by kind, with anything that has since been removed from its manifest.Run it
/api/statsGETThe corpus counts and when the index was last rebuilt. This is where every figure on this site comes from.Run it
/api/healthGETLiveness, for anything polling it.Run it

What the data is, and is not

Everything here is derived from what a registry actually served. The access verdict is a measurement — an item endpoint was fetched and either answered or returned 401 — and unknown means the registry serves no item endpoint we could ask, which is deliberately neither free nor paid.

There is no quality score, no rating and no ranking of registries against each other, because a crawler cannot establish any of those. Ordering by stars orders by GitHub stars and means nothing more than that. Licence fields are the string the repository published; they are not a licence interpretation and are not advice.

Errors are JSON too — { "error": "…" } — so a consumer never has to parse an HTML error page. If a call times out it is the database waking up rather than a result; the same call a moment later will answer.
