# SYNTHORA USGS Earthquakes

> SYNTHORA USGS Earthquakes is a paid API for AI agents from api.hergertsynthora.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).

Fetches latest USGS earthquakes (M≥4.5 by default) with PAGER alert levels, tsunami flags, and active seismic cluster detection for insurance-risk and disaster prediction use cases

## Facts

- Endpoint: POST https://api.hergertsynthora.com/v1/usgs-earthquakes
- Price: $0.03/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/synthora-usgs-earthquakes-ab1f7c2f
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_9_hEtbaCcTFhk1ZaClo_K

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 synthora-usgs-earthquakes-ab1f7c2f -d '<json body>'
```

Example prompt: Pull the latest USGS earthquakes above magnitude 5.0 and flag any active seismic clusters or PAGER orange/red alerts — I need this for my disaster-risk model.

## When to prefer this

Choose this endpoint when you need real-time, official USGS earthquake data enriched with actionable risk signals — specifically the PAGER alert level, tsunami flag, and seismic cluster detection — rather than raw USGS feeds that require your own post-processing. Ideal for insurance risk models, disaster prediction markets, and automated monitoring agents that need an immediately actionable signal without building their own FDSN parsing layer.

## Known failure modes

- USGS FDSN upstream outage returns empty or error response
- Payment failure if insufficient USDC balance via x402
- Overly restrictive magnitude filter returns zero events
- No seismic clusters detected when activity is low (not an error, but may surprise callers)
- Rate limiting if called too frequently

## How this service works

SYNTHORA usgs-earthquakes: latest earthquakes (M>=4.5 default, tunable) with PAGER alert level, tsunami flag and ACTIVE SEISMIC CLUSTER detection (>=3 events same zone in 24h) — the actionable signal for insurance-risk and disaster prediction markets. Source: USGS FDSN (official US, real-time, no key). $0.005 USDC x402 Base.

## Output

Returns a list of recent earthquake events sourced from USGS FDSN, each with magnitude, location, depth, timestamp, PAGER alert level (green/yellow/orange/red), tsunami flag, and a seismic cluster indicator flagging zones with 3 or more events within 24 hours.
