# x402.forgemesh.io Local Seismic Search

> x402.forgemesh.io Local Seismic Search is a paid API for AI agents from x402.forgemesh.io, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Returns all earthquakes above a magnitude threshold within a specified radius of a given latitude/longitude, including depth, time, and tsunami flag, sourced from the official government seismic catalog.

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 x402-forgemesh-io-local-seismic-search-a1ff0c86 -d '<json body>'
```

Example prompt: Can you search for all earthquakes above magnitude 3.0 within 75 km of San Francisco (37.77, -122.42) using the seismic catalog and tell me if any of them triggered a tsunami warning?

## When to prefer this

Use this endpoint when you need site-specific seismic history or hazard assessment for a single location rather than a global or regional stream. Ideal for facility risk dashboards, construction site checks, insurance underwriting, or any agent task that requires point-and-radius earthquake exposure data with tsunami flags and depth information.

## Known failure modes

- Invalid or out-of-range latitude/longitude returns an error
- Radius too large may return an empty result or time out
- No earthquakes found in area returns empty list
- Missing required fields (latitude/longitude) causes request failure
- Payment failure (x402) prevents call from completing

## How this service works

Point-and-radius earthquake search backed by the official government seismic seismic catalog: pass a latitude, longitude, and radius to get every quake above a magnitude threshold in that area, with depth, time, and tsunami flag. Use for site-specific hazard checks, facility-risk dashboards, and agents that need earthquake exposure for one location rather than a global stream.

## Output

A list of earthquake events within the specified radius, each including magnitude, depth (km), UTC timestamp, tsunami flag, and geographic coordinates — sourced from the official government seismic catalog.
