# greeneris-data-geo-quakes

> greeneris-data-geo-quakes is a paid API for AI agents from data.greeneris.io, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Fetch recent earthquake events filtered by location, magnitude, time range, and alert level from the USGS Earthquake Hazards Program

## Facts

- Endpoint: GET https://data.greeneris.io/v1/geo/quakes
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/greeneris-data-geo-quakes-6b698a1c
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_a1oEjCzJIs4UzTZRJYARo

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 greeneris-data-geo-quakes-6b698a1c
```

Example prompt: Can you pull the last 10 earthquakes with magnitude 5 or above that happened within 500 km of Tokyo between July 1 and July 13, 2026, using the USGS data?

## When to prefer this

Use this endpoint when you need real-time or recent USGS earthquake data with flexible filtering by geography, magnitude, time window, or alert level. Prefer it over general web search when you need structured, machine-readable seismic event data at low cost per call. Ideal for AI agents monitoring hazards, assessing risk near a location, or building situational awareness for emergency response workflows.

## Known failure modes

- No earthquakes match the filters — returns count 0 and empty array
- Invalid date format for starttime/endtime — returns 400 error
- latitude/longitude out of range — returns 400 validation error
- maxradiuskm without latitude/longitude — likely ignored or error
- limit exceeds 100 — schema validation error
- HTTP 402 returned if payment not provided — must pay 0.002 USDC via x402 protocol before retrying

## How this service works

Latest earthquakes from the USGS real-time catalog (public domain, updated within minutes). Query: ?minmagnitude=4.5&limit=20; optional starttime/endtime (ISO 8601), geographic filter latitude+longitude+maxradiuskm, alertlevel=green|yellow|orange|red (PAGER). Returns a normalized list: magnitude, place, UTC time, coordinates, depth, tsunami flag, significance. 5 min cache.

## Output

A JSON object containing a count of matching earthquakes and an array of quake records, each with a USGS event ID, magnitude, depth in km, geographic coordinates, place name description, UTC timestamp, tsunami flag, alert level, number of felt reports, and a significance score. Also includes the data source attribution.
