# LuaRocks: one giant manifest file, no REST search

## Probe 1 — `manifest-5.1.json` is the whole registry in one response

```
curl -D- "https://luarocks.org/manifest-5.1.json"
```

`HTTP 200`, `content-type: application/json`, `transfer-encoding: chunked`
(no `content-length` sent, but the downloaded body is 1,706,164 bytes —
1.7 MB). Top-level shape: `{"commands": {}, "repository": {<rock name>: {<version>: [{"arch": "rockspec"}, {"arch": "src"}, ...]}}}`
for every rock ever published for Lua 5.1 compatibility (the manifest is
keyed per Lua version — `manifest-5.1.json`, `manifest-5.4.json`, etc. are
separate full files, not filtered views of one master list).
`X-Cache-Status: HIT` shows this file is cached whole, not assembled
per-request — fetching it is the intended way to "query" LuaRocks.

## Probe 2 — `/search` is server-rendered HTML with no JSON alternative found

```
curl -D- "https://luarocks.org/search?q=penlight"
```

`HTTP 200`, `content-type: text/html` — no `Accept: application/json`
variant was found to change this (unlike Hackage's identical-URL content
negotiation); LuaRocks' human-facing search page appears to be the only
query surface, backed by the flat manifest file for programmatic use.

## Why it matters

An agent wanting "search LuaRocks for X" has no endpoint to call; the only
reliable programmatic path is downloading the ~1.7 MB manifest for the
target Lua version and filtering client-side, exactly like Julia's General
registry and opam's package index (see those records) — a third ecosystem
in this lane with no query API, just a flat full-dump file.
