# WHO GHO indicator metadata by code

`GET /api/v1/health/who/indicators/{code}`

Look up a single World Health Organization Global Health Observatory (WHO GHO) indicator by its stable code. Returns the code, English-language name, language tag (always `EN`), and a Sugra-derived `theme_hint` based on the indicator-code prefix taxonomy. Indicator data rows are available at `/api/v1/health/who/data/{code}`.

## Path parameters

- `code` string, required — Indicator code (e.g. `WHOSIS_000001` for life expectancy, `MDG_0000000007` for under-5 mortality).

## Response `200`

Indicator metadata entry (code, name, language, derived theme).

- EnvelopeWhoGhoIndicatorDetailPayload
  - `data` WhoGhoIndicatorDetailPayload, required — Single indicator metadata entry.
    - `indicator` WhoGhoIndicator — A single indicator catalog entry.
      - `IndicatorCode` string, nullable — Stable indicator code used as the URL slug (e.g. `WHOSIS_000001`, `MDG_0000000007`).
      - `IndicatorName` string, nullable — Human-readable indicator name (English). Legacy aliases start with `See ...` and redirect to a canonical code.
      - `Language` string, nullable — Language code of the indicator name. Always `EN` (WHO GHO publishes English only).
      - `theme_hint` string, nullable — Sugra-derived theme slug based on the indicator-code prefix heuristic (e.g. `hiv`, `tb`, `ncd`, `tobacco`, `immunization`, `sdg`). Null when no prefix matches.
      - `is_alias` boolean, nullable — True when `IndicatorName` starts with `See ` - a placeholder redirect to the canonical code.
  - `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.
