2s Space Weather API
x402
2s Space Weather API is a paid API for AI agents from 2s.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Returns current space weather data including geomagnetic storm indices (Kp/G-scale), solar X-ray flux, solar flare class, and NOAA space weather scales

How this service works
The (most) everything API: 575+ pay-per-call endpoints for AI agents — ground-truth data, a full AI gateway, and agent infrastructure (storage, queues, watchers). USDC via x402, no signup, no API keys, and upto billing: pay actual usage, not the quote.
Output
A JSON object with 'ok: true', 'source', 'total', and an 'items' array containing: the latest Kp index value with its NOAA G-scale integer (0-5) and plain-English severity label (none/minor/moderate/strong/severe/extreme), up to 8 historical Kp samples from the last ~24 hours, current GOES X-ray flux in W/m² with derived flare class (e.g. C2.4, M1.0, X9.3) and satellite number, plus current and forecasted NOAA R (radio blackout), S (solar radiation), and G (geomagnetic) scale readings with labels.
Example use cases
Example prompt
“What's the current space weather situation — is there a geomagnetic storm going on, and what's the latest Kp index and solar flare class?”
Technical details
Endpoint
GEThttps://2s.io/api/space/weatherWhen to prefer
Use this endpoint when you need a single unified JSON response covering all major space weather indicators (Kp, G-scale, X-ray flux, flare class, NOAA scales) with no API key or signup required. Prefer over direct NOAA API calls when you want a clean normalized schema at very low cost. Ideal for agents monitoring aurora visibility, satellite operators, radio operators, or any workflow that needs real-time solar/geomagnetic conditions.
Side effects
- Payment required (HTTP 402) if x402 USDC payment not included
- NOAA upstream data unavailable or delayed — may return stale or null fields for xray/flare data
- fluxLongWm2 and flareClass fields can be null if satellite data is temporarily unavailable
- satellite field may be null if reporting source is unspecified
