/diseases/charts

Returns a list of charts (graphs) that match your filters—each item identifies the disease, country, chart title, type, and a link (`href`) to fetch the full chart data. Results are sorted by title and **limited to 1000** items per request. #### **Required (at least one)** Provide at least one non-empty value using **one or more** of these query parameters (comma-separated where multiple values are allowed): | Parameter | Description | | --- | --- | | `diseases` | Disease IDs | | `countries` | Country codes (see `/diseases/fingerprint/countries`) | | `states` | State or province codes | | `countryregions` | Country region identifiers | | `keywords` | Words or phrases to find in chart titles | If you omit all of the above, the API returns **400** with a short `message` explaining that a filter is required. #### **Optional** | Parameter | Description | | --- | --- | | `type` | Limit results to one or more chart types (comma-separated) | Use **`GET /diseases/charts/countries`** and **`GET /diseases/charts/regions`** to list **`countries`**, **`states`**, and **`countryregions`** values that appear in the chart catalog. Use **`GET /diseases/charts/keywords`** (parameter **`q`**) to suggest **`keywords`** for the title search on **`GET /diseases/charts`**. When you already know the disease id, **`GET /diseases/{disease_code}/charts`** returns every catalog row for that disease across countries. For **every chart in one country** without building filters, **`GET /diseases/countries/{country_code}/charts`** returns the same style of rows for that country only. Typical fields in each result include disease and country names, codes, chart identifier, title, type, and `href` for the follow-up chart request.
