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 scrapemole-pulse-us-national-weather-service-forecast-9e2b09fc
```

Example prompt: Pull the official NWS weather forecast for Austin, TX including any active watches or warnings — give me the day/night periods for the next couple of days.

## When to prefer this

Use this endpoint when you need official, authoritative US government weather forecasts from the National Weather Service — especially when life-safety decisions, compliance, or official sourcing matters. Prefer this over generic weather APIs when you need active alert/watch/warning data for US locations, or when the government-backed source is important. For non-US locations, use the companion global weather endpoint (MET Norway). This endpoint is ideal for US-centric agents, emergency preparedness workflows, event planning, and any use case requiring NWS grid-level forecast precision.

## Known failure modes

- Location not found or outside US/territories: NWS only covers US locations, non-US coordinates will fail
- Invalid place name: ambiguous or non-existent US city names may return an error
- NWS API outage: upstream api.weather.gov may be temporarily unavailable
- Missing required input: must provide either lat+lon or place parameter
- hours out of range: hourly periods parameter must be 1-48
- Payment failure: x402 USDC payment not settled before response is served

## How this service works

Pay-per-call "state of the world" lookups that language models cannot know on their own: official ECB exchange rates (latest, historical, conversion), the current time and DST-aware time-zone conversion for scheduling, global weather forecasts (MET Norway, by coordinates or place name), official US National Weather Service forecasts and active watches/warnings/advisories (by state, point, place or zone), the live Hacker News front page, public holidays for ~100 countries (list by year, check a date, next holidays, long weekends, available countries via Nager.Date), and geocoding / reverse geocoding (place or address ↔ coordinates via Photon and Nominatim over OpenStreetMap). Public, non-personal data with sources and licences in every response. USDC via x402, no accounts.

Payments: x402 v2, scheme "exact", USDC on Base (eip155:8453). The payment is verified before the work and settled only when the response is 200. Terms: https://pulse.scrapemole.workers.dev/terms

## Output

Returns a JSON object with an array of forecast periods (name, start/end times, temperature in F and C, wind speed/direction, short and detailed forecast text, precipitation probability, daytime flag), active weather alerts (count and event list), source URL, license info, update timestamp, and full location metadata (city, state, lat/lon, NWS grid ID and coordinates, county, time zone, forecast zone).
