# EU Financial Sanctions Files (webgate.ec.europa.eu/fsd/fsf)

The EU's consolidated financial-sanctions list is served behind `webgate.ec.europa.eu`, the
same ECAS-session-gated infrastructure used across European Commission systems.

```
curl -sS -D - -o /dev/null https://webgate.ec.europa.eu/fsd/fsf
```
→ `HTTP/1.1 401 Unauthorized`, `Proxy-support: Session-based-authentication`, no body — the
SPA root requires an authenticated ECAS session just to load.

The actual file download is a separate, nominally public, endpoint:
`/fsd/fsf/public/files/xmlFullSanctionsList_1_1/content?token=<value>`. Three distinct
request shapes, three distinct results:

```
curl -sS https://webgate.ec.europa.eu/fsd/fsf/public/files/xmlFullSanctionsList_1_1/content
```
→ `403 Forbidden`, clean JSON body:
```json
{"timestamp":"2026-10-05T08:44:50.969+00:00","status":403,"error":"Forbidden","message":"","path":"/fsd/fsf/public/files/xmlFullSanctionsList_1_1/content"}
```
Identical response with `?token=` (present but empty) — the server treats absent and
empty-string identically.

```
curl -sS -D - https://webgate.ec.europa.eu/fsd/fsf/public/files/xmlFullSanctionsList_1_1/content?token=<placeholder>
```
(a short, obviously-non-UUID placeholder string, not a leaked or guessed real token) →
`HTTP/1.1 500 Internal Server Error`, **empty body**, `Content-Length: 0`. A present-but-wrong
`token` crashes the handler into a bare 500 instead of the clean 403 the no-token path returns
— an unhandled exception path, not a deliberate refusal. Both the 403 and the 500 paths set
fresh `FSD_SESSIONID` and `XSRF-TOKEN` cookies per request (no session reuse observed across
calls).

No bulk download was completed in this observation — characterizing the refusal/crash shape
was the goal, not pulling the dataset, and no real token was constructed or tried.

How observed: 2026-10-05T08:44Z, curl GET against three request shapes (root SPA, no-token
content endpoint, garbage-token content endpoint).
