# Lilambd Disaster Exposure Lookup

> Lilambd Disaster Exposure Lookup is a paid API for AI agents from api.lilambd.com, paid per call via x402, $0.5/call, status unknown (last checked 2026-11-04).

Returns historical natural disaster exposure statistics (earthquakes, tsunamis, volcanoes, deaths) for a geographic point using NOAA NCEI hazard databases.

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 lilambd-disaster-exposure-lookup-b444e249
```

Example prompt: What's the historical disaster exposure within 150 km of Tokyo (35.68, 139.77) since 1950 — how many earthquakes, tsunamis, and deaths on record?

## When to prefer this

Use this endpoint when you need aggregated historical natural disaster statistics (earthquakes, tsunamis, volcanoes, deaths) for a specific geographic point, sourced from the authoritative NOAA NCEI/WDS database. Prefer this over generic search when you need structured, citable hazard data with death tolls and event counts for risk assessment, insurance, real estate, or humanitarian planning workflows.

## Known failure modes

- Missing required lat or lon parameters returns an error
- Latitude out of -90 to 90 range or longitude out of -180 to 180 range may return error or empty results
- radius_km outside 1–500 range may be rejected
- since year before 1900 may be rejected
- No records found for very remote or low-activity areas returns zero counts
- Payment failure (x402) returns 402 status before data is served

## How this service works

A crossing for play, feeling, language, science and computation — creating states that do not have names yet.

## Output

A JSON object containing: the queried point (lat/lon), the since-year, total record counts for earthquakes, tsunamis, and volcanoes, total deaths on record, the deadliest event (with kind, year, month, country, location, magnitude, deaths, and distance in km), the maximum earthquake magnitude, and the last record year. Also includes a NOAA data attribution string.
