| cap | No | Maximum body characters allowed in the window. | |
| eli | No | European Legislation Identifier of the work served (e.g. "http://data.europa.eu/eli/reg/2016/679/oj"); a consolidated text carries its own point-in-time ELI (e.g. "http://data.europa.eu/eli/reg/2016/679/2016-05-04"), a corrigendum its own. Absent when CELLAR records none, as for case law, proposals, and national measures. | |
| date | No | Document date in ISO 8601 format (YYYY-MM-DD). | |
| ecli | No | European Case Law Identifier of a case-law record (e.g. "ECLI:EU:C:2014:317"), as eurlex_lookup_celex reports it: the work's own, or the lowest another work holding the same CELEX records. Absent for legislation. | |
| error | No | Present when the call failed. Absent on success. | |
| shown | No | Number of body characters returned. | |
| title | No | Document title in the language the body is served in (see language), or in English when CELLAR records no title in that language. Case law is titled in English whatever the language, parsed from its English CELLAR title: the parties (e.g. "Google Spain SL and Google Inc. v Agencia Española de Protección de Datos (AEPD) and Mario Costeja González."), or the court/AG descriptor when the case names none, with the rest in formation, referring_court, subject_matter, and case_reference, when the parser places the title whole; otherwise the raw "#"-delimited English title, or the served language's raw title when there is no English one. Absent for some older works and judgments. | |
| notice | No | How to retrieve the remaining document content; when select.annexes asked for "ANNEX" on an act whose annexes are numbered, which numbers select one; when work_uri names an expression or manifestation, the work served in its place; when a work_uri carries several CELEX numbers, how many it carries and which one was served; and, when no consolidated version is in effect yet, that the consolidated text served does not apply yet, or that resolve "current_consolidated" served the base act. | |
| content | No | Body content of the act in the requested format and language. In "paged" mode this is the requested window; in "full" mode it starts at zero; under select it is the matched sections joined in document order, each source character once — a section inside another selected section (an article in a selected chapter) is carried inside the enclosing one. Every one is capped at 100000 characters. Omitted in "metadata_only" mode, when the window is empty, or when content is unavailable. | |
| outline | No | Structural outline of the act. Present only when outline is true; an empty array means no structure was detected. | |
| has_more | No | True when body content exists beyond the returned contiguous window. Continue in "paged" mode with offset = content_offset + content_chars_returned until false. Always false in "metadata_only" mode, and always false for outline and select responses, where that recipe cannot resume across disjoint slices — a cut selection is disclosed through the truncated enrichment instead. | |
| in_force | No | Whether the act is currently in force — for a consolidated text, whether its base act is. When false, repealed_by, entry_into_force, and end_of_validity give the reason where CELLAR records one: an explicit repeal, an entry into force still ahead, or an end of validity — past for an expired act, possibly still ahead for one not yet in force. Some acts not in force carry none of them. | |
| language | No | Language code of the returned content. | |
| work_uri | No | CELLAR work URI. | |
| formation | No | Case law: the formation that decided, from the title's leading segment, verbatim (e.g. "Grand Chamber"), or "President", "Vice-President", or "President of the Second Chamber" for an order issued by that office. Absent when the title names none. | |
| selection | No | Outcome of a structural selection. Present only when select was used; content holds the matched sections joined in document order, a nested section's text once inside its enclosing section, capped at 100000 characters. When the cap cuts the join, a trailing matched section may be partly or wholly absent from content — read selected_sections for each one's own address. | |
| truncated | No | True when the returned body window was capped. | |
| legal_basis | No | Legal basis acts for this work — for a consolidated text, its base act's. Absent when none are recorded. | |
| limit_clamp | No | Present only when limit exceeded the per-call maximum: the value asked for and the value served. The response follows the applied value. | |
| repealed_by | No | CELEX numbers of the acts that explicitly repeal this one, the relation eurlex_get_relations names repealed_by (implicit repeals are listed there as implicitly_repealed_by). Present only when in_force is false; for a consolidated text, its base act's. | |
| celex_number | No | Confirmed CELEX number for the retrieved work. | |
| content_mode | No | Content mode applied to this response: "metadata_only", "paged", or "full". | |
| oj_reference | No | Official Journal reference the act was published under, e.g. "OJ L 119, 4.5.2016, p. 1–88", "OJ 13, 21.2.1962, p. 204–211" (before 1968, no series letter), "OJ L 42I, …" (an issue class other than R), or for act-by-act publication "OJ L, 2024/1689, 12.7.2024" and "OJ C, C/2024/2664, 29.4.2024". Pages are the English edition's, or before 1973 the original-language edition's; an act also reprinted in a later issue cites the earliest. For a consolidated text, its base act's. Absent when CELLAR records no publication. | |
| is_superseded | No | Whether a newer consolidated version (an unofficial reading aid merging later amendments) than the text served is in effect, so this text may lack those amendments. False when the text served is the newest consolidated version in effect, or a consolidated version dated after it that does not apply yet. Not a repeal/replacement signal — the base act remains the law and may still be in force (see in_force). Present whenever the act has a consolidated version in effect; absent otherwise. | |
| resource_type | No | Human-readable document type label (e.g. "Regulation", "Directive"). Absent for some older works. | |
| base_act_celex | No | CELEX of the base act a consolidated text consolidates (e.g. 32024R1689), linked through CELLAR rather than derived from the consolidated CELEX. Its authors, in-force status, legal basis, and EuroVoc subjects are reported here in place of the consolidation's own. Absent for a base act, and for a consolidated text whose base act is unlinked or carries no CELEX. | |
| case_reference | No | Case law: the case reference from the title (e.g. "Case C-131/12."). | |
| content_format | No | Format of the returned content: "html", "markdown", or "xml". | |
| content_offset | No | Character offset where the returned contiguous window begins. Present in "paged" and "full" modes. Absent for outline and select responses, whose content is not a contiguous span — read selected_sections for each matched section's own offset. | |
| content_status | No | Body resolution status: "not_requested" for metadata-only calls, "available" when a body was resolved, or "unavailable" after ordinary resolution attempts returned no usable body. | |
| subject_matter | No | Case law: the subject-matter keyword list from the title (e.g. "Personal data – Protection of individuals …"). | |
| dates_of_effect | No | Every date of effect CELLAR records for the act, sorted by date, one entry per date and type (a date can carry two, e.g. entry into force and application), whether past or ahead and whatever in_force says. For a consolidated text, its base act's. Absent when none is recorded. | |
| end_of_validity | No | Date (YYYY-MM-DD) the act's validity ends or ended: past for an expired act, and possibly in the future for one not yet in force (read it with entry_into_force), so on its own it does not mean the act expired. Present only when in_force is false and CELLAR records an actual date rather than its open-ended 9999-12-31; for a consolidated text, its base act's. | |
| referring_court | No | Case law: the national court that referred a preliminary ruling, from the title (e.g. "Audiencia Nacional"). Absent on direct actions and appeals. | |
| requested_celex | No | The originally requested CELEX, echoed when resolve "current_consolidated" served a different consolidated version. celex_number holds the CELEX actually served. Absent when the served work is the one requested. | |
| entry_into_force | No | Earliest entry-into-force date (YYYY-MM-DD) of an act not yet in force. Present only when in_force is false and that date is after today (UTC); for a consolidated text, its base act's. Every recorded date, typed, is in dates_of_effect. | |
| eurovoc_subjects | No | EuroVoc subject classifications — for a consolidated text, its base act's. Absent when none are recorded. | |
| national_measure | No | National implementing measure publication citation and notification facts recorded on the served work. Missing facts are omitted; no source URL is inferred. | |
| advocates_general | No | Advocates General who delivered this case-law record, by surname as CELLAR records it (e.g. ["Jääskinen"]), sorted. A few Opinions of the Court list several. Absent for legislation and for case law with none recorded. | |
| content_available | No | Whether body content was fetched from EUR-Lex. False in "metadata_only" mode (no fetch attempted) — use content_mode to distinguish "not requested" from "unavailable upstream". | |
| content_omissions | No | Known source omissions; an available body can still omit substantive tables. | |
| language_fallback | No | Human-readable note explaining the fallback that occurred (e.g. "Requested FR content unavailable; returned EN"). Present only when a fallback happened. | |
| selected_sections | No | Source address of each distinct section the selection located, in document order. Present only when select was used. A section nested inside another selected section keeps its own entry, though its text appears in content only once, inside the enclosing section. A selection is a set of slices, not a contiguous window, so these addresses — not content_offset — are how a caller navigates one; every section stays individually reachable even when the cap cut its text. | |
| author_institution | No | Primary (first) author, by the English label of its CELLAR authority code: an EU institution or body (e.g. "European Parliament", "Court of Justice", "European Union"), a member state on a national implementing measure (e.g. "Netherlands"), an MEP by surname on a parliamentary question (e.g. "VAN MIERT"), "Provisional data" for a consolidated text with no linked base act, or for a national-court decision the deciding court (e.g. "Supremo Tribunal de Justiça"). A code with no English label shows the last segment of its code. Each label is accepted by the author_institution filter of eurlex_search_documents. For co-legislated acts, prefer author_institutions for the complete set. For a consolidated text, the base act's (see base_act_celex). Absent when not recorded, and for an AG opinion whose only recorded author is the Advocate General. | |
| consolidated_as_of | No | Consolidation date of current_consolidated_celex in ISO 8601 (YYYY-MM-DD). Present whenever is_superseded is. | |
| requested_language | No | Originally requested language code when English fallback changed the effective language reported in language. | |
| structure_detected | No | Whether any structure was parsed from the body. Present when outline or select was used; false means no detectable chapter/article/annex structure, or for case law no section heading or operative part — read it via offset/limit or content_mode "full". | |
| author_institutions | No | All authors, labelled as in author_institution and listed once each, for acts adopted by more than one body (e.g. ["European Parliament", "Council of the European Union"]) or signed by several states. Advocates General appear in advocates_general instead. For a consolidated text, the base act's. Absent when none recorded. | |
| content_chars_total | No | Total character length of the full document body. Present when content was fetched and available; use with content_offset to page through the entire act. | |
| content_chars_returned | No | Number of body characters returned in this response (equals content length). Present when a body was fetched and available. | |
| transposition_deadlines | No | A directive's deadlines for transposition into national law, sorted. For a consolidated text, its base act's. Absent when none is recorded. | |
| current_consolidated_celex | No | CELEX of the act's newest consolidated version in effect (e.g. 02014R0833-20260424) — fetch it with eurlex_get_document, or pass resolve "current_consolidated". A consolidation dated in the future is never this version. Present whenever is_superseded is. | |
| alternative_representations | No | Verified alternative PDF stream locations; no claim that they contain every omitted table. | |
| content_unavailability_reason | No | Why content_status is "unavailable": no representation exists, the upstream request failed, or a multipart Formex body could not be assembled completely. | |
