# Saylor Innovations Solar Wind Data

> Saylor Innovations Solar Wind Data is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-28).

Returns real-time solar wind conditions from NOAA SWPC including speed, proton density, temperature, dynamic pressure, and interplanetary magnetic field (Bt/Bz) with storm-coupling interpretation

## Facts

- Endpoint: GET https://saylorinnovations.com/api/space/solar-wind?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-28
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/saylor-innovations-solar-wind-data-29783c0c
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_sSztTD2Jn-Xb7i25Eo1Oh

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-solar-wind-data-29783c0c
```

Example prompt: What are the current solar wind conditions right now — speed, density, magnetic field Bz, and whether there's any geomagnetic storm coupling happening?

## When to prefer this

Choose this endpoint when you need live, structured solar wind telemetry with pre-interpreted storm-coupling context and speed categorization — rather than parsing raw NOAA JSON feeds yourself. Ideal for space weather monitoring agents, aurora chasers, radio operators, and satellite operators who need a single clean call with semantic labels (speed category, Bz interpretation) rather than raw numbers.

## Known failure modes

- NOAA SWPC data feed temporarily unavailable — upstream outage may return null or stale values
- Missing optional fields (density, temperature, Bz) returned as null when spacecraft telemetry is incomplete
- Rate limiting or payment failure returns HTTP 402 if USDC payment not processed
- Stale timestamp if NOAA has not refreshed its feed recently

## How this service works

Real-time solar wind from NOAA SWPC - speed with a category, proton density, temperature, dynamic pressure, magnetic field Bt and Bz and a storm-coupling reading

## Output

A JSON object containing the current solar wind speed in km/s with a speed category label, proton density, temperature in Kelvin, dynamic pressure in nPa, interplanetary magnetic field total strength (Bt) and southward component (Bz) in nanoTesla, a storm-coupling interpretation of Bz, the source spacecraft name, a last-hour data array, data timestamp, and a source citation note.
