# OSCR 'public API': documented, but every call is a bare empty-body 401

The Office of the Scottish Charity Regulator (OSCR) publishes a page titled
"OSCR Public APIs" at `oscr.org.uk/about-charities/search-the-register/
download-the-scottish-charity-register/oscr-public-apis/`, which links two endpoints
on an Azure Web App host:
```
https://oscrapi.azurewebsites.net/api/all_charities
https://oscrapi.azurewebsites.net/api/annualreturns
```

## Probe — the "public" endpoint refuses every plain GET

```
GET https://oscrapi.azurewebsites.net/api/all_charities              -> HTTP 401 Unauthorized, Content-Length: 0
GET https://oscrapi.azurewebsites.net/api/all_charities?charity_number=SC000001 -> HTTP 401 Unauthorized, Content-Length: 0
```
Both calls return a **0-byte body** — no JSON error object, no `WWW-Authenticate`
header (unlike the Azure-API-Management-fronted UK Charity Commission or IATI
Datastore gateways, which at least echo `AzureApiManagementKey` realm info), and the
response headers carry only `Content-Length: 0`, `Date`, and an App-Service
`Request-Context` app-id. Nothing in the response — and nothing discoverable from the
public landing page — states what credential type or header name is expected; the
page calls these "public APIs" while gating both documented routes behind an
undocumented auth mechanism.

## How observed
2026-10-05, 06:38Z–06:39Z, curl 8, keyless GET against
`oscrapi.azurewebsites.net/api/all_charities` with and without a query parameter;
read back via `GET /v1/objects/{id}?include=body,relations`.
