# Brazilian municipalities (N6)

`GET /api/v1/statistical-agencies/ibge/municipalities`

5,570 Brazilian municipalities identified by 7-digit IBGE codes. The full payload is 2.4 MB - pass `state` (UF sigla like `SP` or numeric UF code like `35`) to scope to one state. Upstream: `/api/v1/localidades/municipios` or `/api/v1/localidades/estados/{UF}/municipios`. Source: Instituto Brasileiro de Geografia e Estatistica (IBGE).

## Query parameters

- `state` string, nullable — UF filter - sigla (SP, RJ, MG, ...) or numeric UF code (35, 33, 31). Omit for all 5,570.

## Response `200`

Array of municipality entries (5,570 full; fewer when `state` filter is applied).

- EnvelopeIbgeMunicipalitiesPayload
  - `data` IbgeMunicipalitiesPayload, required
    - `municipalities` object[], required — Brazilian municipalities. Full payload is 2.4 MB; use the `state` filter for lighter responses.
    - `count` integer, required — Count of municipalities returned.
    - `state_filter` string, nullable — UF code applied (SP, 35, ...), if any.
  - `meta` SugraMeta, required — Metadata attached to every /api/v1/* response envelope.
    - `endpoint` string, required — Requested endpoint path.
    - `data_time` string, required — ISO 8601 UTC timestamp of the source data, not of the request.
    - `response_time` string, required — ISO 8601 UTC timestamp when this response was produced.
    - `provider` string, required — API name and version.
    - `source` string, nullable — Identifier of the primary upstream source used for this response.
    - `attribution` string, nullable — Human-readable attribution mandated by an upstream source (e.g. a securities regulator or self-regulatory organization). Present only on responses whose source requires the owner and source to be clearly identified. Do not remove or alter it when using the response.
    - `fallback_used` boolean, nullable — True when the primary source failed and a fallback produced the data.
    - `fallback_chain` string[], nullable — Ordered list of sources attempted, in the order they were tried.
    - `cached` boolean, nullable — True when this response was served from the internal cache.
    - `stale` boolean, nullable — True when the cached response was returned after the upstream rate-limited or errored. Clients can use this to detect degraded data.

## Other responses

- `401` — Missing or invalid `x-api-key` header. JSON body with a stable `code` distinguishing `missing_api_key` (no header sent) from `invalid_api_key` (header sent, key not accepted); any other 401 source carries the generic `unauthorized` with its detail as `reason`. Plus `hint`. `plan` is always null on 401 - an unauthenticated request has no plan; quota exhaustion is 429, not 401.
- `422` — Validation Error
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
