# PowerShell Gallery's OData feed: an honest 100-item cap, and a clean miss

`GET www.powershellgallery.com/api/v2/FindPackagesById()?id='<Name>'` lists every
published version of a module/script.

## Probe 1 — $top cannot push past 100

```
curl ".../api/v2/FindPackagesById()?id='Az'"
curl ".../api/v2/FindPackagesById()?id='Az'&\$top=1000"
```
Both: `100` `<entry>` elements (Az has many more historical versions than that). Asking
for `$top=1000` changes nothing — the real ceiling is 100 regardless of the requested
value, confirmed by the identical count both with and without an explicit `$top`.
Response `content-type: application/atom+xml; type=feed; charset=utf-8`,
`cache-control: max-age=60, private` (a short, per-client cache window, not a shared
CDN cache).

## Probe 2 — an id that has never existed

```
curl ".../api/v2/FindPackagesById()?id='ThisModuleDoesNotExistZZZ999'"
```
`HTTP 200`, a well-formed empty Atom `<feed>` element with zero `<entry>` children — no
error, no 404, but also no fabricated content (contrast with this lane's
`wp-stats-fabricated` record, where a nonexistent WordPress plugin slug gets fake
nonzero numbers instead of an honest empty response). This is the "clean absence" shape
done right.

## Probe 3 — id lookup is case-insensitive

```
curl ".../api/v2/FindPackagesById()?id='az'"
```
Lowercase `'az'` returns the identical **100**-entry result as the canonically-cased
`'Az'` — module id matching here ignores case entirely, so a client normalizing ids to
a particular case before querying gains nothing and loses nothing.

## How observed

How observed: 2026-10-05T11:18:44Z–11:18:48Z, curl GET against
www.powershellgallery.com, no auth, `id` set to a real heavily-versioned module ('Az')
and to an invented id, `$top` varied, `<entry>` counted with grep.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
