How this service works
NASA data APIs with x402 micropayment access. Near Earth Objects, Space Weather (DONKI), and Astronomy Picture of the Day.
Output
Returns structured space weather event data from NASA DONKI, including details on solar flares (classification, peak time, location), coronal mass ejections (speed, type, associated activity), and geomagnetic storms (Kp index, intensity level, timestamps).
Example use cases
Real-time space weather alerts for operations
“Check NASA's latest space weather data and let me know if there are any active solar flares or geomagnetic storms that might affect our satellite communications today.”
Track solar activity for power grid planning
“Pull the most recent coronal mass ejections and geomagnetic storm intensity levels from NASA DONKI so we can assess potential grid impact over the next 48 hours.”
Monitor space weather for mission timing
“What's the current geomagnetic activity and are there any solar flares happening right now? We need to know before we launch our spacecraft tomorrow.”
Technical details
Endpoint
GEThttps://nasa.memoryapi.org/x402/nasa/donkiWhen to prefer
Use this endpoint when you need authoritative NASA DONKI space weather event data (solar flares, CMEs, geomagnetic storms) with per-call micropayment pricing via x402. Prefer over direct NASA API access when you need a simple, pay-per-use wrapper without managing NASA API keys. Ideal for agents that need occasional space weather lookups without a subscription commitment.
Side effects
- NASA DONKI API unavailable or rate-limited — upstream service outage
- No events found for requested date range — returns empty dataset
- Invalid date range parameters — returns 400 error
- Payment not processed — x402 payment required before data is returned
- Timeout if NASA upstream is slow to respond
