WHO Global Health Observatory — 3,059 indicators across 194 member states.
Server tool list (6)
Raw names from tools/list. Only developers need these.
| who_list_dimensions | List all dimension type codes and human-readable titles available in the WHO Global Health Observatory API. Use this to discover valid dimension codes before calling who_list_dimension_values. Common dimensions include COUNTRY, REGION, SEX, WORLDBANKINCOMEGROUP, and AGEGROUP, but many additional types exist — this tool exposes them all. |
| who_list_dimension_values | List valid codes and labels for a WHO GHO dimension type such as COUNTRY, REGION, SEX, WORLDBANKINCOMEGROUP, or AGEGROUP. Use this to discover valid filter values before calling who_query_indicator_data, or to confirm the correct ISO code for a country. Use who_list_dimensions to discover all available dimension type codes. Results are paged in a deterministic order — narrow hierarchical dimensions with parent_code (e.g. the countries in one WHO region), and page the rest with offset. |
| who_search_indicators | Search the WHO Global Health Observatory indicator catalog by keyword in the indicator name. Returns indicator codes and names for use with who_query_indicator_data. The search uses a substring match on indicator names — try terms like "life expectancy", "immunization", "mortality", "diabetes", or "HIV". If results are truncated, refine the query or page further into the same filtered result set with offset. |
| who_list_indicators | Browse the WHO Global Health Observatory indicator catalog with pagination. Use when you want to explore indicators without a keyword, or to page through the full catalog. Use who_search_indicators when you have a keyword to narrow the results. |
| who_get_indicator_metadata | Fetch metadata for one or more WHO GHO indicator codes: the full indicator name and the dimensions it supports (e.g. COUNTRY, REGION, SEX, YEAR, WORLDBANKINCOMEGROUP, AGEGROUP). Call this before querying data with who_query_indicator_data to confirm which filter dimensions are valid for a given indicator. Accepts up to 10 codes per call. Many valid indicators have no dimension listing upstream — those return an empty dimensions array with a dimensionsNote, not a not-found. Only codes absent from the catalog are reported in the notFound array, and that is reported rather than raised as an error. |
| who_query_indicator_data | Query data rows for a single WHO GHO indicator with optional spatial, temporal, and dimension filters. Returns rows with numeric values, uncertainty intervals (Low/High), and spatial/time metadata. This is the primary data-fetching tool in the find-then-query workflow: use who_search_indicators to find the indicator code, optionally call who_get_indicator_metadata to confirm which filter dimensions are valid, then call this tool. Spatial filters are mutually exclusive per call: provide only one of country_codes, region_codes, or income_group_codes — mixing them triggers an error. Omitting all spatial filters returns all geographies (may be large; use limit to cap). The sex filter only applies when the indicator uses SEX as its first cross-cutting dimension — if not, the filter returns empty rows; check who_get_indicator_metadata first if uncertain. Rows are returned in a deterministic order (most recent first by default), so a capped result is the top of a defined slice rather than an arbitrary sample; page through the rest with offset. |
