# 460 M49 geographies (countries + regional aggregates)

`GET /api/v1/un-sdg/geo-areas`

UN M49 numeric geography codes used by the SDG database. Covers 460 entries: countries, SDG regions, World, LDCs (Least Developed Countries), LLDCs (Land-Locked Developing Countries), SIDS (Small Island Developing States). Each row is annotated with an ISO 3166-1 alpha-3 code when Sugra's curated map matches (regional aggregates and micro-states return null iso3_code). Source: `/GeoArea/List`. Cached 24 hours.

## Response `200`

M49 geography dictionary with names and best-effort ISO3 annotations.

- EnvelopeSdgGeoAreasPayload
  - `data` SdgGeoAreasPayload, required
    - `geo_areas` SdgGeoArea[], required — M49 geographies (460 countries and regional aggregates).
      - `geoAreaCode` string, nullable — UN M49 numeric code as string (e.g. '840' for United States, '4' for Afghanistan, '1' for World).
      - `geoAreaName` string, nullable — Geography name (country or regional aggregate).
      - `iso3_code` string, nullable — ISO 3166-1 alpha-3 code when Sugra's curated map has a match. Regional aggregates and micro-states return null.
      - `parent_code` string, nullable — Parent M49 code when published by upstream (typically the SDG regional grouping).
    - `count` integer, required — Number of geographies returned.
  - `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.
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
