AEML Drought Region Gauge
x402
AEML Drought Region Gauge is a paid API for AI agents from aeml-x402.zeabur.app, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-13).
Returns a multi-leg drought causal chain for a US region: hydrometeorological precursors (precipitation deficit, soil moisture, snowpack), official US Drought Monitor D0–D4 severity grades by county/state, and realized downstream impacts (crop VHI, reservoir storage, water restrictions, agricultural and power exposure).

How this service works
[3-LEG] Drought chain, one drought region (?entity=us-california): leading precipitation deficit, soil moisture and snowpack -> current the OFFICIAL US Drought Monitor class and area coverage -> realized realized streamflow and impact (confirmation gate). A sequential chain, not one reading - confidence = how many legs are lit, in order. Sources: USDM/NDMC, USGS. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.
Output
A structured JSON object with: a `legs` map containing per-signal readings (signal_id, current value, observed_at, data_age_hours, record_hash) for upstream hydrometeorological signals (precipitation deficit, soil moisture, snowpack) and downstream impact signals (crop VHI, reservoir storage, water restrictions, agricultural/power exposure); a `cross_line_narrative` describing how the legs interrelate; `provenance` with data lineage, freshness, and age metadata; a `_citation` object with Ed25519-signed, offline-verifiable fact claims; `decision_points` listing swappable entity tags; `grade` and `scope` disclaimers; and a `nature` statement clarifying the data is observational, not predictive or advisory.
Example use cases
Parametric drought insurance screening
“I need to assess whether drought conditions in Texas currently meet a D2 or worse threshold — can you pull the official US Drought Monitor grades for Texas along with soil moisture deficits and any crop VHI impacts right now?”
Commodity trader crop stress check
“I'm trading corn futures and want to know if the drought in us-iowa is actually showing up in crop health — pull me the VHI, the USDM drought grade, and tell me if the precursor signals match the crop stress.”
Water utility operational risk review
“Our water utility serves the Phoenix metro area — can you check the current drought severity for us-arizona, including reservoir storage levels and any active water restriction orders, so we can assess operational exposure?”

Endpoint
GEThttps://aeml-x402.zeabur.app/gauge/drought-regionWhen to prefer
Choose this endpoint when you need a single-call, multi-leg drought causal chain for a US region combining official USDM severity grades with upstream hydrometeorological precursors and downstream agricultural/water impacts — especially for parametric drought insurance screening, commodity risk agents, water utility exposure checks, or climate-aware financial workflows. Prefer this over single-signal weather APIs when cross-validation between precursor and impact signals is needed. Not suitable for water management decisions, investment advice, or non-US regions.
Side effects
- Invalid or unrecognized entity key returns an error (422 or 4xx)
- Payment not received or x402 handshake fails — endpoint returns 402 Payment Required
- Data source temporarily unavailable — provenance may flag leg as stale or missing
- Region outside US coverage — entity not supported
- Leg marked dead_source if an upstream data feed (e.g. NOAA-STAR) has frozen or been deprecated
