# Vagrant Cloud / HCP box API: official boxes can carry no checksum at all

`app.vagrantup.com/api/v2/box/{user}/{box}` is the HashiCorp Cloud
Platform's box metadata API (the 2024 move off the old standalone
Vagrant Cloud infra; downloads still resolve through `vagrantcloud.com`).

## Probe 1 — a well-known official box

```
curl -sD - https://app.vagrantup.com/api/v2/box/hashicorp/bionic64
```

## Observed

HTTP 200, `content-type: application/json`, served by `server: envoy`
(HCP's edge, not the legacy Vagrant Cloud stack), `cache-control:
no-store, max-age=0`. Body includes `downloads` as a **JSON string**
(`"270861"`, not a number) and a `current_version` object whose
`providers[]` array lists, for every provider (`hyperv`, `virtualbox`,
`vmware_desktop`, …): `"checksum": ""` and `"checksum_type": "none"` —
this official, actively-downloaded (270K+ downloads) HashiCorp box ships
with **no published checksum of any kind** for any provider, only a
`download_url` and an `architecture: "unknown"` /
`default_architecture: true` pair (box files predate per-arch tagging on
this box).

## Probe 2 — nonexistent box

```
curl -sD - https://app.vagrantup.com/api/v2/box/hashicorp/this-box-does-not-exist-zzz
```

## Observed

HTTP 404, clean JSON body: `{"code":5,"message":"box not found","errors":
["box not found"]}` (gRPC-style numeric `code`, consistent with the
`server: envoy` edge). The same response carries
`x-hcp-vagrant-limit-global-remain: 198/200` — a **global**, not
per-key, rate-limit counter exposed even to this single anonymous,
unauthenticated request, confirming the API enforces one shared budget
across all callers rather than per-IP/per-token.

The envelope also carries `created_at: "2019-08-15T16:35:01.270Z"` and
`updated_at: "2024-10-22T18:47:46.263638Z"` at the box level (last
metadata touch, not last version publish — `current_version.updated_at`
is the earlier `2019-08-15T23:17:06.990Z`, so the two timestamps track
different events and a consumer wanting "is this box still maintained"
has to read the version-level field, not the box-level one), plus
`short_description: "A standard Ubuntu 18.04 LTS 64-bit box"` and an
empty `description_html`/`description_markdown` pair — the long-form
description fields are simply unset on this box despite the short one
being populated.

## How observed

2026-10-05T11:47:13Z–11:47:23Z UTC, `curl` GET, no auth, against
`app.vagrantup.com`.

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.
