# SYNTHORA Space Weather

> SYNTHORA Space Weather is a paid API for AI agents from api.hergertsynthora.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-15).

Returns live space weather data from NOAA SWPC including GOES X-ray flux, solar wind plasma, and planetary Kp geomagnetic index

## Facts

- Endpoint: POST https://api.hergertsynthora.com/v1/space-weather
- Price: $0.03/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/synthora-space-weather-35b70efe
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_xjWwBx1ju2ZHTpY7n0s_b

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 synthora-space-weather-35b70efe -d '<json body>'
```

Example prompt: What's the current space weather looking like — pull the latest GOES X-ray flux, solar wind speed and density, and Kp geomagnetic index from NOAA right now.

## When to prefer this

Use this endpoint when you need live, keyless NOAA space weather data without setting up a direct NOAA API integration. Ideal for agents that need occasional or real-time space weather snapshots at low cost ($0.01 USDC). Prefer this over direct NOAA calls when operating within a micropayment-native agentic workflow using x402 on Base.

## Known failure modes

- NOAA SWPC upstream service unavailable — no data returned
- Invalid focus keyword provided — may return all data or an error
- Payment not processed — 402 response requiring 0.01 USDC on Base
- Stale data if NOAA feed is delayed or down

## How this service works

SYNTHORA space-weather: live space weather from NOAA SWPC — GOES X-ray flux (solar flare activity), solar wind plasma (speed and density) and planetary Kp geomagnetic index. Optional focus: send xray, wind or kp in the input to get just that series, otherwise the latest reading of all three. Source: services.swpc.noaa.gov, keyless, timestamped. $0.01 USDC on Base.

## Output

Returns the latest timestamped readings from NOAA SWPC: GOES X-ray flux (indicating solar flare intensity), solar wind plasma speed and density, and the planetary Kp index (geomagnetic activity level). If a focus parameter (xray, wind, or kp) is provided, only that series is returned.
