Returns US mortality data from CDC NCHS — either annual leading-cause death counts and age-adjusted rates by state (1999–2017) or provisional weekly death counts by jurisdiction (2020–2023)

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability 2s-io-cdc-mortality-statistics-08a92d0c
```

Example prompt: Pull me the CDC leading-causes mortality data for California, filtering for Heart disease deaths in 2015 — I want the annual death count and age-adjusted death rate per 100k.

## When to prefer this

Choose this endpoint when you need official US mortality statistics from CDC NCHS — either historical annual leading-cause death data by state (1999–2017) or provisional weekly death counts including COVID-19 (2020–2023). Prefer this over general web search when you need structured, queryable, public-domain federal mortality data with consistent column schemas. Best for epidemiological analysis, public health research, or trend comparisons by state and cause.

## Known failure modes

- Invalid state name (must be full name like 'California', not abbreviation 'CA') returns no results or error
- Year out of range for dataset (leading-causes: 1999–2017; weekly-counts: 2020–2023) returns empty result set
- Cause string mismatch (case-sensitive or typo) returns no matching rows
- Offset beyond available data returns empty rows array
- Upstream CDC data unavailability causes 5xx or timeout

## How this service works

US mortality statistics from CDC NCHS. dataset=leading-causes (default): annual deaths + age-adjusted death rate per 100k by state and top-10 cause of death, 1999-2017 — filter by state (full name, e.g. "California", or "United States"), year, cause (e.g. "Heart disease", "Cancer", "Suicide"). dataset=weekly-counts: provisional weekly death counts by jurisdiction with per-cause columns (all-cause, natural, COVID-19, heart disease, cancer, etc.), 2020-2023 — filter by state and mmwrYear. Rows returned raw from CDC with documented column names. Public-domain federal data.

## Output

Raw rows from the CDC NCHS dataset with documented column names. For leading-causes: state, year, cause of death, number of deaths, and age-adjusted death rate per 100,000 population. For weekly-counts: jurisdiction, MMWR year/week, and per-cause columns including all-cause, natural causes, COVID-19, heart disease, cancer, and more.
