# Saylor Innovations Space Weather Now

> Saylor Innovations Space Weather Now is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Returns real-time space weather data including NOAA geomagnetic storm, radio blackout, and solar radiation scales, Kp index, solar wind speed and Bz component, aurora outlook, and 3-day storm probabilities.

## Facts

- Endpoint: GET https://saylorinnovations.com/api/spaceweather/now?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-16
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/saylor-innovations-space-weather-now-d475cd57
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_WnvmDU7CiGvff1hJV2-89

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 saylor-innovations-space-weather-now-d475cd57
```

Example prompt: What's the current space weather situation — give me the NOAA geomagnetic storm level, Kp index, solar wind speed and Bz, radio blackout status, and whether there's a good aurora outlook right now.

## When to prefer this

Choose this endpoint when you need a single consolidated real-time space weather snapshot covering all major NOAA scales, Kp index, solar wind parameters, and aurora outlook in one call. Prefer it over manually querying NOAA APIs when you need structured JSON output ready for agent consumption, or when building aurora-watching, ham radio, satellite operations, or space weather alerting workflows.

## Known failure modes

- NOAA upstream data unavailable — may return null fields or stale data
- Network timeout if NOAA feed is slow
- HTTP 402 if payment not included or USDC balance insufficient
- Null values for fields when real-time observation data is temporarily missing

## How this service works

Space weather now - NOAA geomagnetic storm, radio blackout and solar radiation scales, Kp index and 24h peak, live solar wind speed and Bz, aurora outlook and 3-day probabilities

## Output

A JSON object with current NOAA space weather scales (geomagnetic storm G0–G5, radio blackout R0–R5, solar radiation storm S0–S5), estimated Kp index and 24-hour maximum Kp, live solar wind speed and Bz value, aurora outlook description, 3-day forecast probabilities, observation timestamp, and data source attribution.
