Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 us-drought-monitor-area-statistics-by-region-2daf5811
```

Example prompt: What are the current US Drought Monitor conditions for Texas — I want to see the percentage of the state in each drought category from D0 to D4, plus how it changed from last week.

## When to prefer this

Use this endpoint when you need official US Drought Monitor categorical drought percentages (D0–D4) for a specific geographic area — whether national, state-level, or county-level — including historical weekly trends and week-over-week changes. Prefer this over general weather APIs that lack drought-specific categorical breakdowns, and over manual USDA/NOAA portal lookups when you need machine-readable JSON for downstream analysis or automated monitoring.

## Known failure modes

- Invalid area code returns an error or empty result — must use 'us', a valid two-letter state abbreviation, or a valid 5-digit county FIPS code
- Stale data if US Drought Monitor has not yet published the current week's release (typically updated Thursday)
- Unknown FIPS codes for territories or unrecognized regions may return null values
- Network or payment authentication failure (402 not satisfied) blocks response

## How this service works

US Drought Monitor percent of area in each drought category D0-D4 for the US, any state or county FIPS, with weekly history and weekly change

## Output

A JSON object containing: the area label, the latest week's drought percentages broken down into none/D0/D1/D2/D3/D4 categories with valid date range and map date, an array of prior weekly snapshots for historical trending, weekly change values, the data source attribution, and any relevant notes or caveats.
