## Pricing

Pay per usage

This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Japan Earthquake Feed API (JMA)

Live earthquake data for Japan from the official Japan Meteorological Agency public feed.

Use this Actor when you need a simple API for recent earthquakes in and around Japan: magnitude, epicenter in Japanese and English, maximum JMA seismic intensity, coordinates, depth, event time, and report time.

### Why use it

- Official JMA source, not a scraped news page.
- Structured rows ready for dashboards, alerts, maps, RAG, and monitoring bots.
- Japanese and English epicenter names in the same output.
- No proxy or browser dependency, so runs are fast and cheap.

### Common use cases

- Disaster monitoring dashboards for Japan operations.
- Alert enrichment for earthquakes above a chosen magnitude.
- Location intelligence and risk workflows for logistics, travel, insurance, and facilities.
- AI agents that need current Japan seismic data instead of stale training data.

### Input

| Field | Type | Description |
|---|---|---|
| `minMagnitude` | number | Return only earthquakes at or above this magnitude. Default `0`. |
| `limit` | integer | Maximum number of recent records. Default `50`, max `844`. |

```json
{ "minMagnitude": 4.5, "limit": 100 }
```

### Output

One dataset row per earthquake:

| Field | Meaning |
|---|---|
| `time` | Earthquake occurrence time |
| `reported_at` | JMA report time |
| `epicenter_ja` / `epicenter_en` | Epicenter name in Japanese and English |
| `magnitude` | Magnitude, when available |
| `max_intensity` | JMA maximum seismic intensity code |
| `latitude` / `longitude` | Epicenter coordinates |
| `depth_km` | Depth in kilometers |
| `title` | JMA event title |

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {};

// Run the Actor and wait for it to finish
const run = await client.actor("grinning_naiad_h0w/jp-earthquake-feed").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = {}

# Run the Actor and wait for it to finish
run = client.actor("grinning_naiad_h0w/jp-earthquake-feed").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{}' |
apify call grinning_naiad_h0w/jp-earthquake-feed --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,grinning_naiad_h0w/jp-earthquake-feed"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
