Behavior: read-only and idempotent — a live GET against the public IBGE Localidades API. Returns a Markdown record.

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)

• 6706: GDP at current prices

• 5938: GDP per capita

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"

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="" (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.

• Female names: tipo="ranking", sexo="F"

Behavior: read-only and idempotent — a live GET against the public IBGE Nomes (Censo) API. Returns a Markdown table.

Searches and lists already-published IBGE news articles and press releases.

Use this to find recent IBGE publications or announcements about a survey or topic — when an indicator was released, or news mentioning a term like "censo". Results are sorted newest-first; with no parameters it returns the 10 most recent items.

Parameters:

• busca: free-text term to match (e.g. "PIB", "censo")

• tipo: "release" (official publication of survey results) or "noticia" (general news); omit for both

• de / ate: date range, format DD/MM/AAAA (e.g. de="01/01/2024", ate="31/12/2024")

• destaque: true to return only featured items

• quantidade: how many to return (default 10, max 100); pagina: page number to page through more

Each item returns: title, type (release/news), publication date, editoria (section), related products/surveys, a featured flag, a plain-text summary, and a link to the full article. The header reports the total count and current page.

Examples:

• Latest 10 news: (no parameters)

• Search census: busca="censo"

• 2024 news: de="01/01/2024", ate="31/12/2024"

• Releases only: tipo="release"

Use a different tool when:

• Scheduled/upcoming release dates (not yet published) → ibge_calendario

Behavior: read-only and idempotent — a live GET against the public IBGE Notícias API. Returns a Markdown list.

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.

Returns metadata for a specific SIDRA table.

Features:

• General info (name, survey, subject, periodicity)

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.

• 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).

This tool is the panel for a SINGLE municipality (Cidades@). Use a different tool when:

• Census themes / historical series → ibge_censo

• Comparing multiple municipalities → ibge_comparar

• A macro indicator time series → ibge_indicadores

Behavior: read-only and idempotent — uses the public IBGE Pesquisas (Cidades@) API and Localidades lookup; panorama may combine several indicator calls and explicitly reports partial upstream gaps. Returns Markdown plus a typed structuredContent payload.

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.

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.
