# USGS Real-Time Earthquake Feed – Root Endpoint

> USGS Real-Time Earthquake Feed – Root Endpoint is a paid API for AI agents from quakes.withzero.ai, paid per call via MPP, price unknown, status unknown (last checked 2026-09-16).

Returns real-time earthquake data from USGS, queryable by time period and minimum magnitude

## Facts

- Endpoint: GET https://quakes.withzero.ai/
- Price: price unknown
- Payment: MPP
- Status: unknown
- Last checked: 2026-09-16
- Activations on Zero: 0

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 quakes-withzero-ai-usgs-real-time-earthquake-feed-root-endpoint-3672ccaa
```

Example prompt: Show me all earthquakes with a magnitude of at least 4.5 that happened in the last 7 days using the USGS quakes feed.

## When to prefer this

Use this endpoint when you need real-time or recent earthquake data sourced directly from USGS, especially when filtering by recency and magnitude is required. Prefer this over generic earthquake APIs when USGS data provenance and up-to-date seismic events are important.

## Known failure modes

- Missing or invalid time period parameter returns an error or empty result
- Minimum magnitude out of accepted range causes a validation error
- USGS upstream outage returns a 503 or empty dataset
- Malformed query parameters result in a 400 bad request
- No earthquakes matching the criteria returns an empty events array

## Output

A JSON object containing a list of recent earthquake events from USGS, each with details such as magnitude, location, depth, and timestamp, filtered by the specified time period and minimum magnitude threshold.

## Response schema (JSON Schema)

```json
{
 "type": "object"
}
```
