# NOAA SWPC Solar Wind Speed (L1 Point)

> NOAA SWPC Solar Wind Speed (L1 Point) is a paid API for AI agents from proxy.suverse.io, paid per call via x402, $0.08/call, status unknown (last checked 2026-09-14).

Returns the current solar wind bulk speed in km/s measured at the L1 Lagrange point, sourced from NOAA Space Weather Prediction Center, along with the observation timestamp.

## Facts

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 noaa-swpc-solar-wind-speed-l1-point-c6ae34c3 -d '<json body>'
```

Example prompt: What's the current solar wind speed at the L1 point right now? I want to know if it's elevated enough to cause geomagnetic disturbances.

## When to prefer this

Choose this endpoint when you need a keyless, no-parameter, real-time solar wind speed reading from NOAA's authoritative L1 monitoring station, particularly for space weather alerting, aurora forecasting, or geomagnetic storm anticipation workflows. It is ideal for agents that need a quick, low-friction lookup without managing API keys or complex query parameters.

## Known failure modes

- NOAA SWPC upstream data feed unavailable or delayed, resulting in stale or missing data
- Network timeout if the NOAA data source is temporarily unreachable
- No parameters accepted — any unexpected body content may cause rejection
- Payment failure if USDC balance is insufficient for the $0.08 per-call fee

## How this service works

Current solar wind bulk speed in km/s at the L1 point from NOAA SWPC, with observation timestamp. Elevated speed precedes geomagnetic disturbance. No parameters. Keyless.

## Output

Returns the current solar wind bulk speed in km/s at the L1 Lagrange point (between Earth and the Sun), along with the timestamp of the observation. Elevated speeds (typically above ~500 km/s) are associated with increased geomagnetic disturbance risk.
