Returns Markdown plus a typed structuredContent payload.

Queries Brazil health indicators, served through IBGE's SIDRA (some originally produced by DataSUS, e.g. mortality and births). Mortality and Birth: - mortalidade_infantil: Infant mortality rate - nascidos_vivos: Live births by location - obitos: Deaths by residence Demographic Indicators: - esperanca_vida: Life expectancy at birth - fecundidade: Fertility rate Sanitation: - saneamento_agua: Water supply - saneamento_esgoto: Sewage system Health Coverage: - plano_saude: Health insurance coverage - autoavaliacao_saude: Self-rated health status Territorial levels: 1=Brazil, 2=Region, 3=State, 6=Municipality Examples: - Infant mortality: indicador="mortalidade_infantil" - Life expectancy by state: indicador="esperanca_vida", nivel_territorial="3" - Deaths in SP: indicador="obitos", nivel_territorial="3", localidade="35" - List indicators: indicador="listar" Statistics mode: for largest/smallest/mean/median/distribution/ranking questions ("which state has the highest infant mortality?", "median life expectancy across states") use estatisticas=true — full distribution + top/bottom over ALL rows before truncation; agruparPor="<column label>" ranks groups by descending sum. In this mode campos/formato are ignored and registros comes empty. Use a different tool when: - A single municipality's general panel (which also includes infant mortality) → ibge_cidades - Population/demographic counts (not health-specific) → ibge_censo or ibge_sidra Behavior: read-only and idempotent — a live GET against the public IBGE SIDRA API. Returns Markdown plus a typed structuredContent payload.

Returns Markdown.

Queries IBGE economic and social indicators. Available indicators: **Economic:** - pib: quarterly GDP at current prices, R$ million (Brazil only) - pib_variacao: quarterly GDP volume change, % over the same quarter of the previous year (Brazil only) - pib_per_capita: annual GDP per capita at current prices, R$ (Brazil only) - industria: industrial production index, general industry (2022=100) - comercio: retail sales volume index (2022=100) - servicos: services volume index (2022=100, Brazil only) **Prices:** - ipca: IPCA monthly change, % - ipca_acumulado: IPCA accumulated over 12 months, % - inpc: INPC monthly change, % **Labor:** - desemprego: Unemployment rate - ocupacao: Employed people (thousands) - rendimento: average real income from all jobs, R$ — each period is a ROLLING quarter (e.g. "jun-jul-ago 2026"), Brazil only - informalidade: Informality rate **Population:** - populacao: Population estimate - densidade: Population density Examples: - GDP: indicador="pib" - IPCA last 12 months: indicador="ipca", periodos="last 12" - Unemployment by state: indicador="desemprego", nivel_territorial="3" - List indicators: indicador="listar" Each indicator returns ONE variable — the one its name says; for another one of the same table (e.g. the year-to-date change) use ibge_sidra with variaveis. What each number is: every record carries the SIDRA period column (code and label, e.g. "Mês (Código)" 202403 / "Mês" "março 2024") and the "Variável" label — the only place that says whether a value is a monthly change, a year-to-date or 12-month accumulation, an index number or a level; read it before adding, subtracting or comparing values. A PNAD rolling quarter ("jun-jul-ago 2026") is a three-month window that moves every month, not a calendar quarter. Revisions: values are what SIDRA publishes at the extraction instant (retrieved_at); IBGE revises published figures (quarterly GDP at each release, PNAD reweighting, annual revisions of PIM/PMC/PMS) and the API keeps no earlier version. Statistics mode: for largest/smallest/mean/median/distribution/ranking questions ("which state has the highest unemployment?", "median informality rate across states") use estatisticas=true — full distribution + top/bottom over ALL rows before truncation; agruparPor="<column label>" (e.g. "Unidade da Federação", "Trimestre") ranks groups by descending sum. In this mode campos/formato are ignored and registros comes empty. Use a different tool when: - Comparing/ranking localities → ibge_comparar - Census themes → ibge_censo - One municipality's panel → ibge_cidades Behavior: read-only and idempotent — a live GET against the public IBGE SIDRA API. Returns Markdown plus a typed structuredContent payload.

Features: - State information (2-digit code) - Municipality information (7-digit code) - District information (9-digit code) - Complete hierarchy (region, mesoregion, microregion) Examples: - São Paulo state: codigo=35 - São Paulo city: codigo=3550308 - District: codigo=355030805 This tool returns the full record of ONE locality you already have the code for. Use a different tool when: - You have a name and need the code → ibge_municipios (municipalities) or ibge_geocodigo (any level) - You want to decompose/understand a code's structure → ibge_geocodigo Behavior: read-only and idempotent — a live GET against the public IBGE Localidades API. Returns a Markdown record.

Gets geographic meshes (maps) from IBGE in GeoJSON, TopoJSON, or SVG format. Features: - Meshes for Brazil, regions, states, municipalities - Different resolution levels (internal divisions) - Different quality levels - Formats: GeoJSON (data), TopoJSON (compact), SVG (image) Locality types: - "BR" or "1" = Entire Brazil - State abbreviation (e.g., "SP", "RJ") - State code (e.g., "35" for SP) - Municipality code (7 digits) Resolution (internal divisions): - 0 = Outline only - 2 = States - 5 = Municipalities Examples: - Brazil with states: localidade="BR", resolucao="2" - São Paulo with municipalities: localidade="SP", resolucao="5" - SVG format: localidade="BR", formato="svg" Use a different tool when: - Thematic meshes (biomes, Legal Amazon, semi-arid, metropolitan regions) → ibge_malhas_tema Behavior: read-only and idempotent — a live GET against the public IBGE Malhas API. Returns the mesh in the requested format (GeoJSON, TopoJSON, or SVG).

Lists what a THEMATIC territorial recorte of Brazil contains: how many features, with which codes and names, and the URL to download its geometry. Available recortes: - biomas: the six continental biomes - amazonia_legal: Legal Amazon boundary - semiarido: semi-arid area - costeiro: coastal municipalities - fronteira: border-strip municipalities - metropolitana: metropolitan regions - ride: Integrated Development Regions - listar: the catalogue itself, without querying the source Filtering with `codigo`: only the recortes that have a per-feature code accept it — biomas (the biome code) and the two municipality ones, costeiro and fronteira (the 7-digit IBGE municipality code). Ask without `codigo` to see what exists; biome codes come from the source, not from a fixed table. GEOMETRY IS NOT IN THE RESPONSE, on purpose: one biome polygon alone is over 9 MB. The response carries the attributes plus a canonical WFS URL that returns the recorte with geometry in GeoJSON. Use a different tool when: - Administrative meshes WITH geometry (country/region/state/municipality outlines) → ibge_malhas Behavior: read-only and idempotent — a live GET against the public IBGE Geosserviços WFS (IBGE Geociências), which is a different service from the Malhas API and the only one that publishes these recortes. Returns Markdown plus a typed structuredContent payload.

Lists Brazilian municipalities from IBGE. Features: - List municipalities by state (using state abbreviation) - List all municipalities in Brazil (5,570 municipalities) - Search by municipality name - Returns 7-digit IBGE code Examples: - São Paulo municipalities: uf="SP" - Search by name: busca="Campinas" - MG municipalities containing "Belo": uf="MG", busca="Belo" Use a different tool when: - Resolve/decode a code at any level (region, state, district), not just municipalities → ibge_geocodigo - Full details/hierarchy of one locality by code → ibge_localidade - Neighboring municipalities → ibge_vizinhos Behavior: read-only and idempotent — a live GET against the public IBGE Localidades API.

Queries international country data via IBGE. Features: - List all countries (following UN M49 methodology) - Country details (area, languages, currency, location) with the latest published value of country indicators — by default population, GDP, GDP per capita, HDI and life expectancy - Pick other indicators with indicadores="<ids or aliases separated by |>" - Indicator catalog as published by IBGE (34 indicators: economy, population, health, environment, networks), with unit and scale - Search countries by name - Filter by region/continent Each indicator value is the most recent one the source publishes for that country, with its year or period (some are 3- or 5-year ranges like "2021-2023"), as text (it can be "<2.5"), plus unit and scale (multiplicador) — null when the source has none. Available regions: americas, europa, africa, asia, oceania Country codes: Use ISO-ALPHA-2 (e.g., BR, US, AR, PT, JP) Examples: - List all: tipo="listar" - Brazil details: tipo="detalhes", pais="BR" - Chosen indicators: tipo="detalhes", pais="AR", indicadores="idh|77852" - Search: tipo="buscar", busca="Argentina" - Americas countries: tipo="listar", regiao="americas" - Indicator catalog: tipo="indicadores" Behavior: read-only and idempotent — a live GET against the public IBGE Países API. Returns Markdown.

Lists available IBGE surveys and their tables. Features: - List all IBGE surveys (Census, PNAD, GDP, etc.) - Search by name or code - Show details and tables of a specific survey - Categorize surveys by theme Main surveys: - **Census**: Demographic, Agricultural, MUNIC - **PNAD Contínua**: Employment, income, education - **National Accounts**: GDP, investments - **Economic Surveys**: Industry, Commerce, Services - **Price Indices**: IPCA, INPC Examples: - List all: (no parameters) - Search population: busca="população" - PNAD details: detalhes="pnad" This lists surveys, not data. To find table codes use ibge_sidra_tabelas; to query data use ibge_sidra (or a wrapper: ibge_censo, ibge_indicadores, ibge_comparar, ibge_cidades). Behavior: read-only and idempotent — a live GET against the public IBGE SIDRA/Pesquisas API. Returns a Markdown list.

Queries SIDRA tables (IBGE's Automatic Recovery System). SIDRA contains data from IBGE surveys like Census, PNAD, GDP, etc. Common tables: - 6579: Population estimates (annual) - 9514: Census 2022 population - 200: Census population (1970-2010) - 4714: Population, territorial area and density (Census 2022) - 4099: Unemployment rate (PNAD Contínua, quarterly) - 5436: Average real income (PNAD Contínua, quarterly) - 1846: Quarterly GDP at current prices (Brazil) - 5938: Municipal GDP at current prices (annual, down to municipality) - 6784: Annual GDP and GDP per capita (Brazil) Territorial levels: - 1: Brazil - 2: Region (North, Northeast, etc.) - 3: State (UF) - 6: Municipality - 7: Metropolitan Region Examples: - Brazil population 2023: tabela="6579", periodos="2023" - Population by state: tabela="6579", nivel_territorial="3" - Census 2022 by municipality: tabela="9514", nivel_territorial="6", localidades="3550308" What each number is: every record carries the SIDRA period column (code and label, e.g. "Mês (Código)" 202403 / "Mês" "março 2024") and the "Variável" label — the only place that says whether a value is a monthly change, a year-to-date or 12-month accumulation, an index number or a level; read it before adding, subtracting or comparing values. A PNAD rolling quarter ("jun-jul-ago 2026") is a three-month window that moves every month, not a calendar quarter. Revisions: values are what SIDRA publishes at the extraction instant (retrieved_at); IBGE revises published figures (quarterly GDP at each release, PNAD reweighting, annual revisions of PIM/PMC/PMS) and the API keeps no earlier version. Statistics mode: for **largest/smallest/mean/median/distribution/ranking** questions ("which municipality has the largest population?", "median GDP by state") use estatisticas=true — it computes min/max/mean/median/std-dev/labeled percentiles over ALL data rows BEFORE pagination and returns top/bottom rankings (default 10, cap 100 via topN), so one call answers what would otherwise require paging thousands of records. With agruparPor="<column label>" (e.g. "Unidade da Federação", "Ano") it ranks groups by descending sum, each with its own mini-distribution. Queries mixing several variables auto-group by "Variável" (units differ). SIDRA absence markers ("-", "..", "...", "X") are excluded from n. In this mode pagina/campos/formato are ignored and registros comes empty. Very large queries are refused by the source (since 2026-09-16 SIDRA tables are read through the Aggregates API, whose ceiling is lower than SIDRA's old 100,000-value cap: all municipalities × 12 yearly periods fails, × 8 works) — narrow periodos (e.g. "last 4") or raise nivel_territorial. ibge_sidra is the low-level engine. Prefer a friendlier wrapper when it fits: - Census themes (1970–2022) → ibge_censo - Economic/social time series → ibge_indicadores - Rank/compare 2–10 localities → ibge_comparar - One municipality's panel → ibge_cidades Use ibge_sidra_tabelas and ibge_sidra_metadados to find a table code and its structure before querying. Behavior: read-only and idempotent — a live GET against the public IBGE SIDRA API. Returns Markdown plus a typed structuredContent payload.

Returns metadata for a specific SIDRA table. Features: - General info (name, survey, subject, periodicity) - Available territorial levels - Variable list with units - Classifications and categories - Available periods Use this tool to understand table structure BEFORE querying data with ibge_sidra. Examples: - Population table metadata: tabela="6579" - Census 2022 metadata: tabela="9514" - PNAD unemployment: tabela="4714" Use this after finding a table code (ibge_sidra_tabelas) and before querying with ibge_sidra. Behavior: read-only and idempotent — a live GET against the public IBGE SIDRA API. Returns Markdown.

Lists and searches available SIDRA tables. Features: - List all SIDRA tables (aggregates) - Search by table name: every word must match (AND), accents and case ignored, and everyday Portuguese is resolved to the IBGE's own wording (renda→rendimento, desemprego→desocupação, cidade→município, gênero→sexo); when that happens the response says so in notas_vocabulario - Filter by survey (Census, PNAD, GDP, etc.) - Shows code and name of each table SIDRA contains data from various surveys: - Demographic Census - PNAD Contínua (employment, income) - National Accounts (GDP) - Industrial Survey - Agricultural Survey Examples: - List tables: (no parameters) - Search population tables: busca="população" - Census tables: pesquisa="censo" This is step 1 of the SIDRA workflow: find a table code → ibge_sidra_metadados (structure) → ibge_sidra (query). For common data, a wrapper is usually easier: ibge_censo, ibge_indicadores, ibge_comparar, ibge_cidades. Behavior: read-only and idempotent — a live GET against the public IBGE SIDRA API. Returns a Markdown table.

Finds nearby/neighboring municipalities. Features: - Search by IBGE code (7 digits) or municipality name - Returns municipalities in the same mesoregion (proximity approximation) - Optionally includes population data Note: Uses mesoregion as geographic proximity proxy. For exact spatial neighborhood, mesh processing would be required. Examples: - By code: municipio="3550308" - By name: municipio="Campinas", uf="SP" - With population: municipio="3550308", incluir_dados=true Note: proximity is approximated by shared mesoregion (not exact spatial adjacency). For listing/searching municipalities, use ibge_municipios. Behavior: read-only and idempotent — a live GET against the public IBGE Localidades API. Returns a Markdown list.

Returns the full document for an id obtained from `search`, as { id, title, text, url, metadata }: `text` is the readable content (Markdown) and `url` the canonical public page to cite. Companion of `search` in the OpenAI Deep Research contract, over the IBGE (Brazilian official statistics: SIDRA tables, municipalities, known indicators) catalog. Only ids returned by `search` are valid; an unknown id returns an error. The `ibge_*` tools (`ibge_sidra`, `ibge_cidades`, `ibge_indicadores`, `ibge_comparar`…) remain the tools for data queries. Behavior: read-only and idempotent — a live GET against the public source when the document needs it.

Searches the IBGE (Brazilian official statistics: SIDRA tables, municipalities, known indicators) catalog and returns up to 10 matching documents as { id, title, url }, ordered by relevance (an empty list means nothing matched). This tool exists for the OpenAI Deep Research contract: ChatGPT deep research, company knowledge and research workflows over the Responses API require exactly the tools `search` and `fetch`. Pass one of the returned ids to `fetch` to read the document. For direct questions and for data (values, series, rankings) prefer the `ibge_*` tools (`ibge_sidra`, `ibge_cidades`, `ibge_indicadores`, `ibge_comparar`…), which return the actual data with provenance — this is a catalog index, not a data query. Query: natural language or keywords, Portuguese or English; accents and case are ignored. Behavior: read-only and idempotent — the catalog comes from the public source and is cached in memory.
