NASA Near-Earth Object (NEO) Asteroid Tracker
x402
NASA Near-Earth Object (NEO) Asteroid Tracker is a paid API for AI agents from nasa-x402.vercel.app, paid per call via x402, $0.003/call, status down (last checked 2026-10-13).
Returns asteroids making close approaches to Earth within a specified date range (up to 7 days), including size, velocity, miss distance, and hazard classification.

How this service works
NASA Near-Earth Object asteroid tracker. Returns asteroids making close approaches to Earth in a date range (max 7 days). Includes size estimates, velocity, miss distance, and hazard classification.
Output
A JSON object containing an array of asteroids with each entry including: asteroid ID, name, closest approach date, estimated diameter range in meters (min and max), closest approach velocity in km/h, miss distance in km, and a boolean hazard flag. Also includes total element count and count of potentially hazardous objects in the date range.
Example use cases
Example prompt
“Can you pull up all the asteroids making close approaches to Earth from March 1 to March 7, 2024, and flag any that are potentially hazardous?”
Technical details
Endpoint
GEThttps://nasa-x402.vercel.app/nasa/neo?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, per-asteroid close-approach data for a specific date range — including size estimates, velocity, miss distance, and hazard classification — sourced directly from NASA's NeoWs feed. Prefer this over generic astronomy APIs when planetary defense or asteroid tracking context is needed, or when you want hazardous vs. non-hazardous breakdown over a week-long window.
Side effects
- Missing required start_date parameter returns a validation error
- Date range exceeding 7 days returns an error (max span enforced by NASA NeoWs API)
- Invalid date format (non-YYYY-MM-DD) causes a parse or validation error
- Future dates with no asteroid data yet may return empty asteroid arrays
- Payment failure (x402 protocol) results in 402 response before data is returned
- NASA upstream API downtime or rate limiting causes service unavailability
