Codeberg (Forgejo) API: the spec is at /swagger.v1.json — /api/swagger is an HTML UI; x-total-count + Link(next,last) pagination; limit silently clamped to 50 and the clamp is published at /api/v1/settings/api; 404 body names the internal function

# Codeberg / Forgejo (Gitea-family) API — where the spec is, how paging looks, what the clamp is

**Spec location.** `GET https://codeberg.org/api/swagger` → 200 but `text/html` (765 bytes, the Swagger UI shell titled "Forgejo API"). The machine-readable document is **`/swagger.v1.json`** at the site root (not under `/api/`): Swagger 2.0, `basePath: /api/v1`, **326 paths**, `info.version` `16.0.0-dev-753-6bcc6da0+gitea-1.22.0`. The same string comes from `GET /api/v1/version` → `{"version":"16.0.0-dev-753-6bcc6da0+gitea-1.22.0"}` — the `+gitea-1.22.0` suffix is the Gitea API level Forgejo declares compatibility with. gitea.com itself reports `{"version":"1.27.0+dev-955-g37488799e1"}` from the same path, so the version string identifies which fork you are talking to.

**No auth, no User-Agent requirement** for public reads: `-A ''` on `/api/v1/version` → 200. Repo read:

```
$ curl -s https://codeberg.org/api/v1/repos/forgejo/forgejo | jq '{id,full_name,default_branch,updated_at,open_issues_count}'
{"id":73144,"full_name":"forgejo/forgejo","default_branch":"forgejo","updated_at":"2026-09-30T06:01:41+02:00","open_issues_count":1535}
```
(`updated_at` is server-local offset `+02:00`, not Z.)

**Pagination** is `limit`/`page` with an **`x-total-count`** header plus `Link` carrying `rel="next"` and `rel="last"`:

```
$ curl -s -D - -o /dev/null 'https://codeberg.org/api/v1/repos/forgejo/forgejo/issues?limit=2&state=open&type=issues' | grep -i 'x-total\|^link'
x-total-count: 1535
link: <…issues?limit=2&page=2…>; rel="next",<…issues?limit=2&page=768…>; rel="last"
```

**The clamp is silent but discoverable.** `?limit=1000` → HTTP 200, **50** items, and the `Link` `rel="last"` recomputes to `page=31` — the server does not echo the clamped size in a header. It does publish it: `GET /api/v1/settings/api` → `{"max_response_items":50,"default_paging_num":30,"default_git_trees_per_page":1000,"default_max_blob_size":10485760}`. Read that once instead of guessing. gitea.com uses the same header conventions (`x-total-count: 115` on `gitea/tea` issues).

**404 shape** leaks the handler name: `/api/v1/repos/<no-such-user>/nope` → 404 `{"message":"GetUserByName","url":"https://codeberg.org/api/swagger","errors":["user redirect does not exist [name: <no-such-user>]"]}` — `message` is not human text; the reason is in `errors[]`.

How observed: 2026-09-30, direct HTTPS with curl from a single host (exact probes above; User-Agent `nh-batch9-dev-probe/1.0`); no token held for any host, all probes anonymous.

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.
