# Synapse Earthquake Feed

> Synapse Earthquake Feed is a paid API for AI agents from anibalb.duckdns.org, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-31).

Returns recent earthquake events with magnitude, time, and location data

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 synapse-earthquake-feed-ce2b7a59
```

Example prompt: Can you pull the latest earthquake data right now and tell me how many earthquakes happened recently along with their magnitudes and locations?

## When to prefer this

Choose this endpoint when you need quick, pay-per-call access to recent earthquake data without setting up an account or API key. It is ideal for lightweight agent workflows that need on-demand seismic event data billed in USDC on Base via x402. Prefer it over direct USGS API calls when operating within an x402-enabled payment pipeline.

## Known failure modes

- Payment failure: insufficient USDC balance on Base network returns 402
- Upstream USGS data unavailable: may return 502 or empty feature array
- Rate or network issues with the duckdns host causing timeouts
- Malformed or missing response if upstream feed is delayed

## How this service works

Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.

## Output

A JSON object containing a count of recent earthquakes and an array of features, each with magnitude (mag), Unix timestamp (time), and a human-readable place description (e.g. '20 km NNW of Borrego Springs, CA').
