# Space Weather Solar Flare Now

> Space Weather Solar Flare Now is a paid API for AI agents from space-weather.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).

Returns the current solar X-ray class and details of the latest solar flare including begin, peak, and end times.

## Facts

- Price: $0.02/call
- Payment: x402

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 space-weather-solar-flare-now-d59db80f
```

Example prompt: What is the current solar X-ray class and has there been any solar flare recently — give me the begin, peak, and end times plus the peak flare class?

## When to prefer this

Choose this endpoint when you need a concise real-time snapshot of current solar X-ray conditions and the most recent flare event with precise timing. Prefer it over the broader space weather overview endpoint when your use case specifically concerns X-ray flux and flare classification rather than Kp index, geomagnetic storms, or aurora probability.

## Known failure modes

- NOAA data feed temporarily unavailable — degraded flag set to true
- Null values for latestFlare if no recent flare has occurred
- Stale observedAt timestamp if upstream data has not refreshed
- Network timeout to the x402 endpoint requiring retry
- Payment failure if USDC balance is insufficient for the $0.02 call

## How this service works

Current solar X-ray class (A/B/C/M/X) and the latest flare: begin, peak and end times and peak class.

## Output

Returns the current solar X-ray class (A/B/C/M/X scale), observation timestamp, satellite number used, whether data is degraded, a summary and verdict, and a latestFlare object with begin, max, and end times plus class at each phase, along with radio blackout level and source URL.
