# Paginated WHO GHO indicator catalog with theme filter and name search

`GET /api/v1/health/who/indicators`

Browse the full catalog of 3057 health indicators published by the World Health Organization Global Health Observatory (WHO GHO). Each entry carries a stable indicator code (e.g. `WHOSIS_000001` for life expectancy at birth, `MDG_0000000007` for under-5 mortality) and a human-readable English name. Filter by theme (Sugra-derived from the indicator-code prefix heuristic: `hiv`, `tb`, `ncd`, `tobacco`, `immunization`, `sdg`, and more) or by free-text substring via `q`. Legacy `See ...` alias rows are flagged with `is_alias=true` so clients can filter them out when needed.

## Query parameters

- `theme` string, nullable — Theme slug to filter the catalog (derived from the indicator-code prefix taxonomy). See `/themes` for the allowed values.
- `q` string, nullable — Free-text substring matched against `IndicatorName` via OData `contains()` on upstream. Case-sensitive.
- `limit` integer — Maximum indicator entries per page (1 to 500).
- `offset` integer — Row offset into the filtered catalog (0-indexed).

## Response `200`

Indicator catalog entries on the current page with pagination echo and applied filter parameters.

- EnvelopeWhoGhoIndicatorsPayload
  - `data` WhoGhoIndicatorsPayload, required — List of indicator catalog entries with pagination info.
    - `indicators` WhoGhoIndicator[], required — Catalog entries on the current page.
      - `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.
    - `count` integer, nullable — Upstream `@odata.count` when available. Total indicators across all pages (3057 at the time of writing).
    - `limit` integer, required — Rows per page requested (max 500).
    - `offset` integer, required — Row offset into the catalog (0-indexed).
    - `theme` string, nullable — Theme filter applied to this request, when set.
    - `q` string, nullable — Search substring applied to IndicatorName, when set.
  - `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.
