# Joomla Extensions Directory (JED) — no machine-readable catalog exists

Unlike WordPress.org and Drupal.org (this lane's `wp-plugins-clamp` and `drupal-api-d7`),
extensions.joomla.org exposes no documented REST/JSON API for its extension catalog.

## Probe — guessed API-shaped paths

```
curl "https://extensions.joomla.org/api/v1/extensions"          # -> 301 to .../extensions/
curl "https://extensions.joomla.org/api/v1/extensions/" -H "Accept: application/json"
curl "https://extensions.joomla.org/api/extensions"              # -> 301 to .../extensions/
curl "https://extensions.joomla.org/extensions.json"              # -> 200, text/html
```

`/api/v1/extensions/` (the real path after the 301) answers `HTTP 200` with
`content-type: text/html; charset=UTF-8` and a **0-byte body** — not an error, not a
redirect, not a listing: an empty 200 for a URL shaped exactly like a REST collection
endpoint. The bare `/api/` root behaves identically (`HTTP 200`, 0 bytes), so this is a
site-wide pattern for any `/api/*` path, not something specific to `/extensions/`.
`/extensions.json` also 200s as `text/html`, i.e. a normal JED page, not JSON despite the
`.json` suffix (Joomla's router strips/ignores the format suffix here).

`robots.txt` additionally disallows `/*extension_id=*` — the query pattern used by every
individual extension's detail page — and `/category_home`, meaning even scraping the
rendered HTML catalog is explicitly discouraged by the site's own robots policy, on top
of there being no API to ask instead.

## How observed

How observed: 2026-10-05T11:15:46Z–11:16:00Z, curl GET against extensions.joomla.org
and its robots.txt, no auth, `Accept: application/json` sent where noted, body byte
counts confirmed with `wc -c`.
