With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability nws-weather-alerts-x402-05a8519e ``` Example prompt: Are there any active Tornado or Severe Thunderstorm warnings in Texas right now? Show me up to 10 results. ## When to prefer this Choose this endpoint when you need real-time, official US weather alert data from the National Weather Service, filterable by state, geographic point, event type, or severity. Prefer it over general weather APIs when the focus is on active hazard alerts (warnings, watches, advisories) rather than forecasts or current conditions. Ideal for safety-critical workflows where authoritative government data is required. ## Known failure modes - No alerts found for the given area/event/severity — returns empty list - Invalid state/territory code returns 400 or empty result - Invalid lat/lon format for point parameter causes error - Payment failure or insufficient USDC balance prevents call - Rate limiting or service unavailability on the upstream NWS API causes 503 ## How this service works Pay-per-call data and web utilities for AI agents: web page to Markdown, SEO audit, email check, domain RDAP/DNS and mail security, ECB FX rates, time zones and business days, SEC EDGAR search and fundamentals, Federal Register, USAspending, weather and NWS alerts, VIN, NPI, ATS jobs.
