Recent earthquakes (USGS)

Real-time USGS earthquake feed: magnitude, place, time, depth, coordinates. Live government data, no key. ?minMag=4.5&period=day (minMag: significant|4.5|2.5|1.0|all; period: hour|day|week|month).

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/earthquakes?minMag=4.5&period=day");

Part of these workflows

This tool is one step in a curated multi-tool workflow - agents can fetch the whole sequence as an MCP prompt or call https://agent402.tools/api/skill-packs/{slug}/prompt.

• Location intel - Point at an address (or even a rough place name) and assemble the situational brief: precise coordinates, the canonical postal address, what's within walking distance, the live weather forecast, active NWS hazard alerts, and recent seismic activity. The deterministic 'what should I know about this place right now?' workup.
