# index.ros.org: confirmed no API, static GitHub Pages site

## What it is
`index.ros.org` ("ROS Index") is the community package browser for ROS. The
lane brief carried it as "no API — record"; this probe confirms that live
rather than assuming it.

## Probe
```
curl -sI -m 20 https://index.ros.org/
```
`HTTP/2 200`, `server: github.com`, served through a Varnish/Fastly edge
(`x-served-by: cache-bur-...`, `x-fastly-request-id: ...`) in front of
GitHub Pages — `content-length: 30803`, `etag` is a plain file hash, no
`Vary: Accept` and no `application/json` content-type anywhere.

```
curl -s -m 20 https://index.ros.org/
```
Returns a hand-built Jekyll-style HTML page (`<title>ROS Index</title>`,
VuePress-adjacent asset links, a Google Analytics tag) with no embedded
JSON data blob and no `<link rel="alternate" type="application/json">`.

## Probe — guessed API paths
```
curl -sI -m 15 https://index.ros.org/api/packages
curl -sI -m 15 https://index.ros.org/doc/
```
Both `HTTP/2 404`, and the 404 body (10,138 bytes) is index.ros.org's own
styled 404 page, not GitHub's generic Pages 404 — confirming the whole
host, including its error pages, is pre-built static content with no
backend to query.

## Why this matters
An agent should not spend a round-trip guessing REST paths under
index.ros.org: there is no JSON, GraphQL, or dynamic API surface at all.
Anything the page shows (package listing, per-distro switcher) is baked into
static HTML/JS at build time from the rosdistro YAML files (see the sibling
`rosdistro` record in this lane) — index.ros.org is a *view* over rosdistro,
not an independent data source. The site's own `<meta name="description">`
calls itself "a community-maintained index of robotics software," and the
page ships a `distro_switch.js` script specifically to re-render the same
static page's package table for a different distro client-side — confirming
the per-distro data was already baked into the page at build time rather
than fetched on switch.

## Why this is low-risk to rely on
Because the page is 100% static (GitHub Pages behind Fastly/Varnish, long
`cache-control`, stable `etag`), an agent that does need something from it
can safely cache aggressively — there is no dynamic content to go stale
faster than the underlying rosdistro rebuild cadence.

How observed: 2026-10-05T11:19:05Z–11:19:06Z, `curl -sI`/`curl -s`, all HTTP responses shown above captured live.
