A free `securityToken` is required; nothing is readable without one. Responses, including refusals, are IEC 62325-351 market documents in XML.\n\n**Refusal shape (HTTP 401, `Content-Type: text/xml`, HTTP/1.1):**\n\n```\n<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<Acknowledgement_MarketDocument xmlns=\"urn:iec62325.351:tc57wg16:451-1:acknowledgementdocument:7:0\">\n  <mRID>2e04eefa-8f19-4</mRID>\n  <createdDateTime>2026-09-30T04:50:54Z</createdDateTime>\n  <sender_MarketParticipant.mRID codingScheme=\"A01\">10X1001A1001A450</sender_MarketParticipant.mRID>\n  <sender_MarketParticipant.marketRole.type>A32</sender_MarketParticipant.marketRole.type>\n  <receiver_MarketParticipant.mRID codingScheme=\"A01\">10X1001A1001A450</receiver_MarketParticipant.mRID>\n  <receiver_MarketParticipant.marketRole.type>A39</receiver_MarketParticipant.marketRole.type>\n  <received_MarketDocument.createdDateTime>2026-09-30T04:50:54Z</received_MarketDocument.createdDateTime>\n  <Reason><code>999</code><text>Authentication failed.</text></Reason>\n</Acknowledgement_MarketDocument>\n```\n\n- **No `securityToken` at all** → `Reason/text` = `Authentication failed.` (833 bytes).\n- **A non-UUID-shaped token** (`securityToken=<any-string>`) → `Reason/text` = **`Unauthorized. Missing or invalid security token.`** (859 bytes).\n- **A UUID-shaped but unknown token** (`00000000-0000-0000-0000-000000000000`) → `Authentication failed.` again — so the format check happens *before* the lookup, and only a well-formed token reaches the auth layer. `Reason/code` is `999` in all three; only `text` differs.\n- Query parameters are not validated before auth: `/api` with **no parameters at all** produces the identical 401 document.\n- **`Accept: application/json` switches the refusal to JSON**, HTTP 401, `Content-Type: application/json`: `{\"uuAppErrorMap\":{\"providePublishedData/userNotAuthenticated\":{\"id\":\"…\",\"timestamp\":\"2026-09-30T04:50:58.809Z\",\"type\":\"error\",\"message\":\"Authentication failed.\"}}}` — a completely different envelope (uuApp), so a client that content-negotiates JSON must parse two error grammars.\n\nThe `mRID` on the acknowledgement is 15 characters (a truncated UUID), fresh per request; `sender`/`receiver` are both `10X1001A1001A450` (ENTSO-E's own EIC). Detect refusal by `Reason/code == 999` on the XML path, never by grepping for \"401\" in the body.\n\nProbe:\n\n```\ncurl -s -D - 'https://web-api.tp.entsoe.eu/api?documentType=A44&in_Domain=10Y1001A1001A82H&out_Domain=10Y1001A1001A82H&periodStart=202609290000&periodEnd=202609300000' | grep -E '^HTTP|Content-Type|<text>'\ncurl -s 'https://web-api.tp.entsoe.eu/api?securityToken=<not-a-uuid>&documentType=A44&in_Domain=10Y1001A1001A82H&out_Domain=10Y1001A1001A82H&periodStart=202609290000&periodEnd=202609300000' | grep '<text>'\ncurl -s -H 'Accept: application/json' 'https://web-api.tp.entsoe.eu/api' | head -c 300\n```\n\nHow observed: 2026-09-30, curl 04:50–04:51 UTC, five keyless / placeholder-token GETs (no token, non-UUID token, all-zero UUID, no params, `Accept: application/json`).
