This probes a third\nEUR-Lex surface used for case-law/document expert search: the legacy SOAP webservice\ndefinition, and the human `search.html` endpoint, both with no credential.\n\n## Probe 1 — the SOAP WSDL itself\n\n```\ncurl -s -D - \"https://eur-lex.europa.eu/EURLexWebService?wsdl\"\n```\n\n**Observed:** `200`, `content-type: text/xml;charset=utf-8`, a full JAX-WS-generated WSDL\ndocument (`<!-- Published by JAX-WS RI ... -->`), three session-scoped cookies set\n(`AWSALB`, `AWSALBCORS`, `ELX_SESSIONID`) even for fetching the service **definition** — the\nWSDL/schema is public with no registration, but actually calling the described `doQuery`\nSOAP operation requires an EU Login account and API key per EUR-Lex's own documentation (not\nprobed further here, since that requires registration this lane does not hold).\n\n## Probe 2 — the human expert-search page, no session, no JS\n\n```\ncurl -s -D - -A \"pwx-scout/1.0\" \"https://eur-lex.europa.eu/search.html?scope=EURLEX&text=case-law&lang=en&type=quick\"\n```\n\n**Observed:** `202 Accepted` (not 403), `content-length: 0`, `x-amzn-waf-action: challenge`,\n`cache-control: no-store, max-age=0`, served by CloudFront. The challenge is signaled entirely\nthrough the `x-amzn-waf-action` header on an otherwise-empty `202` body — there is no HTML\nchallenge page, no `Just a moment...` interstitial text, nothing a naive status-code check\n(`if status >= 400`) would catch, because `202` is conventionally a **success** code.\n\n## What this means for an agent\n\nAn agent gating on HTTP status alone (`< 400` means \"fine, proceed\") will treat this AWS WAF\nchallenge as a successful, empty response rather than the block it is — the opposite failure\nmode from a typical 403/429 bot wall, and arguably more dangerous because `202 Accepted` reads\nas \"your request was accepted, content follows\" when in fact zero bytes of actual content were\nreturned and the real page never rendered. The SOAP definition being public while the\ninteractive search page is harder to reach anonymously than the documented, registration-gated\nAPI is also the inverse of the usual pattern (schema gated, actual data endpoint ungated).\n\nHow observed: 2026-10-05, 06:28Z UTC, curl 8, UA default (WSDL) and `pwx-scout/1.0`\n(search.html).
