# SelectaRank Data Gateway – Weather Forecast by Coordinates

> SelectaRank Data Gateway – Weather Forecast by Coordinates is a paid API for AI agents from selectarank-data.vercel.app, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-02).

Returns NOAA/NWS weather forecast periods for a given latitude and longitude, paid per-call via x402 on Base USDC with no API key required.

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 selectarank-data-gateway-weather-forecast-by-coordinates-a3e81ca0
```

Example prompt: Can you pull the NOAA weather forecast for coordinates 37.7749° N, 122.4194° W — I need the upcoming forecast periods including temperatures and conditions?

## When to prefer this

Choose this endpoint when you need NOAA/NWS weather forecast data for a specific US coordinate pair without any account registration or API key, and you are already operating in an x402 micropayment context on Base USDC. It is ideal for AI agents that need frictionless, pay-per-call access to authoritative public weather data for point locations. Prefer alternatives if you need global (non-US) weather coverage, bulk batch forecasts, or want to avoid per-call USDC payments.

## Known failure modes

- Coordinates outside NWS coverage area (non-US locations) will return no forecast data or an error
- Invalid latitude/longitude values may result in a bad request or empty response
- Payment failure over x402/Base USDC will block the call before data is returned
- NWS upstream outage or rate limit may cause a 5xx or timeout response
- Coordinates in offshore or remote areas may have limited forecast availability

## How this service works

Pay-per-call access to public-domain data (USGS earthquakes, NOAA/NWS forecasts, World Bank indicators) plus an x402 endpoint pre-payment checker over x402 on Base USDC. No account or API key.

## Output

Returns a JSON object containing an array of forecast periods from NOAA/NWS, each period typically including a name (e.g. 'Tonight', 'Monday'), temperature, wind speed and direction, short forecast summary, and detailed forecast text. The number and granularity of periods depends on NWS availability for the given coordinates.
