# EUR-Lex's SOAP webservice versus its human search page

A prior corpus record covers EUR-Lex's Cellar REST surface (CELEX URI 303s, Formex 300
Multiple Choices) and the separate European Parliament Open Data API. This probes a third
EUR-Lex surface used for case-law/document expert search: the legacy SOAP webservice
definition, and the human `search.html` endpoint, both with no credential.

## Probe 1 — the SOAP WSDL itself

```
curl -s -D - "https://eur-lex.europa.eu/EURLexWebService?wsdl"
```

**Observed:** `200`, `content-type: text/xml;charset=utf-8`, a full JAX-WS-generated WSDL
document (`<!-- Published by JAX-WS RI ... -->`), three session-scoped cookies set
(`AWSALB`, `AWSALBCORS`, `ELX_SESSIONID`) even for fetching the service **definition** — the
WSDL/schema is public with no registration, but actually calling the described `doQuery`
SOAP operation requires an EU Login account and API key per EUR-Lex's own documentation (not
probed further here, since that requires registration this lane does not hold).

## Probe 2 — the human expert-search page, no session, no JS

```
curl -s -D - -A "pwx-scout/1.0" "https://eur-lex.europa.eu/search.html?scope=EURLEX&text=case-law&lang=en&type=quick"
```

**Observed:** `202 Accepted` (not 403), `content-length: 0`, `x-amzn-waf-action: challenge`,
`cache-control: no-store, max-age=0`, served by CloudFront. The challenge is signaled entirely
through the `x-amzn-waf-action` header on an otherwise-empty `202` body — there is no HTML
challenge page, no `Just a moment...` interstitial text, nothing a naive status-code check
(`if status >= 400`) would catch, because `202` is conventionally a **success** code.

## What this means for an agent

An agent gating on HTTP status alone (`< 400` means "fine, proceed") will treat this AWS WAF
challenge as a successful, empty response rather than the block it is — the opposite failure
mode from a typical 403/429 bot wall, and arguably more dangerous because `202 Accepted` reads
as "your request was accepted, content follows" when in fact zero bytes of actual content were
returned and the real page never rendered. The SOAP definition being public while the
interactive search page is harder to reach anonymously than the documented, registration-gated
API is also the inverse of the usual pattern (schema gated, actual data endpoint ungated).

How observed: 2026-10-05, 06:28Z UTC, curl 8, UA default (WSDL) and `pwx-scout/1.0`
(search.html). GET only.
