# NOAA SWPC Interplanetary Magnetic Field (L1) via Suverse

> NOAA SWPC Interplanetary Magnetic Field (L1) via Suverse 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).

Fetches real-time interplanetary magnetic field data at the L1 Lagrange point from NOAA SWPC, returning total field strength (Bt) and north-south component (Bz) in nanoteslas with a timestamp.

## Facts

- Endpoint: POST https://proxy.suverse.io/v1/data/suverse-swpc-solar-wind-mag
- Price: $0.08/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/noaa-swpc-interplanetary-magnetic-field-l1-via-suverse-06d4aabb

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-interplanetary-magnetic-field-l1-via-suverse-06d4aabb -d '<json body>'
```

Example prompt: What are the current interplanetary magnetic field readings at L1 — specifically the total Bt and the north-south Bz component in nanoteslas — so I can assess geomagnetic storm risk right now?

## When to prefer this

Use this endpoint when you need keyless, no-parameter access to real-time L1 interplanetary magnetic field data (Bt and Bz) sourced directly from NOAA SWPC, especially for geomagnetic storm prediction, aurora forecasting, or space weather monitoring workflows where southward Bz is the key indicator. Prefer this over scraping NOAA directly for reliability and simplicity in agent pipelines.

## Known failure modes

- NOAA SWPC upstream data feed unavailable or delayed — may return stale or empty data
- Payment not processed — 402 response requiring x402 payment of $0.08 USDC
- Network timeout if NOAA data pipeline is experiencing outages
- Malformed response if SWPC data format changes upstream

## How this service works

Interplanetary magnetic field at L1 from NOAA SWPC: total field Bt and north-south Bz in nT with timestamp. Southward Bz is the key storm predictor. No parameters. Keyless.

## Output

Returns the current interplanetary magnetic field readings at the L1 Lagrange point: total field strength Bt in nanoteslas, north-south Bz component in nanoteslas (negative/southward Bz indicates elevated geomagnetic storm risk), and a timestamp for the measurement.
