# SiteCheck Trade & Energy – US Drought Monitor County Statistics

> SiteCheck Trade & Energy – US Drought Monitor County Statistics is a paid API for AI agents from api.tradeenergy-api.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-29).

Returns US Drought Monitor area-percent statistics for a single US county by FIPS code and optional weekly map date, covering no-drought through D0–D4 drought severity categories.

## 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 sitecheck-trade-energy-us-drought-monitor-county-statistics-8ba38710
```

Example prompt: What does the US Drought Monitor say about Fresno County, California (FIPS 06019) for the most recent weekly map — give me the full breakdown of what percentage of the county is in each drought category from D0 to D4.

## When to prefer this

Use this endpoint when you need official US Drought Monitor county-level drought severity area statistics by FIPS code — particularly for agricultural risk assessment, water resource planning, or environmental monitoring workflows. Prefer this over general weather APIs when you specifically need USDM-sourced drought category percentages (D0–D4) for a precise county and week. Not suitable for crop-specific drought indices, sub-county granularity, or non-US regions.

## Known failure modes

- Invalid or non-existent FIPS code returns an error or empty result
- Date not on a Tuesday or not yet available from USDM returns an error or falls back to most recent Tuesday
- USDM upstream API unavailability causes request failure
- FIPS code for a non-county entity (e.g. state-level FIPS) may not be supported
- Future dates or dates before USDM coverage period may return no data

## How this service works

US Drought Monitor county statistics for one US county (5-digit FIPS) and one weekly map date: percent of the county's area in no drought and in drought categories D0 (abnormally dry) to D4 (exceptional), from the USDM public API. County level only; crop-specific indices are not included.

## Output

A JSON object containing the county name, state, FIPS code, map date, the timestamp the data was checked, and a breakdown of the percentage of the county's land area in each drought category: none (no drought), D0 (abnormally dry), D1 (moderate), D2 (severe), D3 (extreme), and D4 (exceptional drought). Values are floating-point percentages that sum to 100.
