# OpenWrt sysupgrade.openwrt.org: overview + revision, both plain GET

## What it is
`sysupgrade.openwrt.org` is the backing API for OpenWrt's attended
sysupgrade tool — it tells a running router what package renames/mandatory
changes apply when upgrading between releases, and what exact source
revision built a given release/target/subtarget image.

## Probe — overview
```
curl -s -m 20 -L https://sysupgrade.openwrt.org/api/v1/overview
```
(Plain `http://`/un-followed requests 301-redirect to `https://` with an
empty body — `-L` is required.) HTTP 200, 18,570 bytes:
```json
{"latest": ["25.12.5", "24.10.8"],
 "branches": {"SNAPSHOT": {"path": "snapshots", "enabled": true, "snapshot": true,
   "package_changes": [
     {"source": "firewall", "target": "firewall4", "revision": 18611},
     {"source": "opkg", "target": "apk-mbedtls", "revision": 28056},
     {"source": "auc", "target": "owut", "revision": 26792},
     {"source": "luci-app-opkg", "target": "luci-app-package-manager", "revision": 27897},
     ...
   ], "versions": ["SNAPSHOT"], ...}}}
```
`package_changes` is the live list an agent would need to know, e.g., that
`opkg` has been renamed to `apk-mbedtls` and `auc` to `owut` as of specific
SVN-style revision numbers, before scripting an unattended sysupgrade.

## Probe — revision lookup
```
curl -s -m 20 -L https://sysupgrade.openwrt.org/api/v1/revision/24.10.8/ath79/generic
```
HTTP 200, tiny body: `{"revision":"r29233-443ec4032a"}` — the exact build
revision string for that release/target/subtarget triple, matched against
what a running device reports to decide if a reflash is actually needed.

## Why this is useful to record
Both endpoints are undocumented outside the sysupgrade client's own source
and return compact, purpose-built JSON (not mirrors of anything on
downloads.openwrt.org) — an agent automating router fleet upgrades needs
exactly this pair of calls and nothing in `downloads.openwrt.org`'s
`profiles.json` exposes package-rename or revision-pin data.

How observed: 2026-10-05T11:22:5xZ, `curl -L` GET, both endpoints, keyless.
