🌍 Weather, Air Quality & Earthquake Risk API by Location

One call, three live sources, one answer. For any point (or many), this fuses current weather + air quality + recent earthquakes into a single computed verdict — clear / caution / hazard — with the exact hazard flags and reasons, instead of making your agent hit three APIs and stitch the result.

Headless · keyless (no API keys to manage) · structured JSON out · built for AI agents.

⚡ Why it's different

Other actors give you raw weather, raw air quality, or raw quakes. This one composes and judges them: strong gusts ☁️ + unhealthy air 😷 + a nearby M5 quake 🌋 → one hazard verdict with the reasons spelled out. Ask once, decide immediately.

📋 What it does & what you get

Field	Meaning
status	Computed verdict: clear · caution · hazard
flags	e.g. high_wind, heavy_precip, low_visibility, poor_air, strong_quake, dark
reasons	Human-readable why (e.g. "notable earthquake nearby (M4.9)")
weather	temp °C, wind & gusts km/h, precip mm, visibility m, is-day, sunrise/sunset, condition
airQuality	PM2.5, PM10, US AQI + band, EU AQI, ozone, NO₂
seismic	count, max magnitude, and the recent events (place, time, depth)
sources	the three upstream sources (attribution)

📥 Input

Field	Type	Meaning
latitude, longitude	number	A single point (decimal degrees)
label	string	Optional name for that point
locations	array	Many points: [{"latitude":35.68,"longitude":139.69,"label":"Tokyo"}]
radiusKm	integer	Earthquake search radius (default 300)
quakeLookbackDays	integer	Days back to search quakes (default 7)
minMagnitude	number	Ignore quakes below this (default 2.5)
onlyAlerts	boolean	Drop clear points (great with a schedule)
webhookUrl	string	POST results here if any (Zapier/Make/n8n/custom)

Example input

💡 Use cases

• Field / drone / outdoor ops: is this site safe to operate right now, and why?
• Logistics & delivery: flag routes/depots hitting severe wind, low visibility or heavy rain.
• Travel & events: a one-shot "is it clear at this destination" check across many points.
• Agent tools: give a location assistant one call instead of three APIs + glue code.
• Scheduled monitoring: watch a set of sites and get pinged only on caution/hazard.

🤖 For AI agents (MCP)

Keyless, one call → a fused, judged answer with the raw sub-data attached for grounding. Every input is described in the schema for programmatic/MCP use. Example MCP server config:

{
  "mcpServers": {
    "location-conditions": {
      "url": "https://mcp.apify.com/?tools=actors,docs,centorprat/weather-air-quality-earthquake-api"
    }
  }
}

Claude Code: claude mcp add --transport http apify "https://mcp.apify.com/?tools=actors,docs,centorprat/weather-air-quality-earthquake-api" --header "Authorization: Bearer <YOUR_APIFY_TOKEN>"

No extra setup: this Actor is callable from Claude, Cursor, ChatGPT or any MCP client through the Apify MCP server, and agents can find it on their own with the server's search-actors tool.

🔔 Alerts (scheduled)

Set onlyAlerts: true + webhookUrl, add an Apify Schedule (e.g. every 30 min), and get pinged only when a watched location turns caution/hazard.

🚀 Ready-made tasks (one click)

Pre-configured runs for the most common jobs. Open one, change the input, run:

• Air Quality & Weather Now for Any City: Current AQI, PM2.5, PM10 and weather for many cities in one call, with a hazard verdict per city. Keyless air quality API.
• Recent Earthquakes Near a Location (USGS): Recent USGS earthquakes near any lat/lon with magnitude, distance and time, plus weather, air quality and a hazard verdict.
• Travel Destination Weather & Hazard Check: Weather, air quality and earthquake check for travel destinations, with a clear/caution/hazard verdict per place. One call, many places.

❓ FAQ

• Do I need an API key? No — all three sources are keyless and free; you only pay the Actor's per-result fee.
• How fresh is it? Weather & air quality are current; earthquakes cover your chosen lookback window (default 7 days).
• How many locations per run? As many as you pass in locations; you're billed per location assessed.
• What makes a hazard vs caution? Severe thresholds (e.g. gusts ≥60 km/h, US AQI ≥151, precip ≥7 mm, M≥5.5) → hazard; moderate thresholds → caution; otherwise clear.
• Why both US and EU AQI? Different regions read air quality on different scales; you get both plus a plain-language band.
• Can I only get alerts? Yes — onlyAlerts: true drops clear points; add webhookUrl to push them out.
• What units? Temperature °C, wind km/h, precipitation mm, visibility m, magnitudes on the USGS scale.
• Is the data stored? No — it's fetched, composed, returned. Nothing is retained.
• Is this legal to use commercially? Yes — Open-Meteo is free for commercial use with attribution; USGS data is U.S. public domain.
• What if a source is down? The row still returns with whatever composed successfully; the failed sub-object carries an error flag.

📜 Data & attribution

Weather & air quality from Open-Meteo (open data, free for commercial use with attribution); earthquakes from the USGS earthquake feed (U.S. public domain). This actor retrieves and composes public data; it stores none of it.
