NASA/JPL Near-Earth Asteroid Close Approaches API (Keyless Proxy)
x402
NASA/JPL Near-Earth Asteroid Close Approaches API (Keyless Proxy) is a paid API for AI agents from proxy.suverse.io, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-16).
Returns near-Earth asteroid close approach data (designation, date, distance, velocity, magnitude) from NASA/JPL CAD API, filtered by date range and/or distance, with no API key required.

How this service works
Near-Earth asteroid close approaches by date and distance: designation, date, distance, velocity, magnitude. Keyless NASA/JPL CAD API. For planetary-defense agents.
Output
Returns a structured list of close approach events, each containing the asteroid's designation (name/ID), close approach date, miss distance (in AU, lunar distances, or km), relative velocity (km/s), and absolute magnitude (H). Data is sourced directly from NASA/JPL CNEOS CAD API.
Example use cases
Planetary defense threat monitoring
“I need a list of all asteroids making close approaches to Earth within 0.02 AU over the next 90 days — include their miss distance, velocity, and magnitude so I can flag any potentially hazardous ones.”
Historical asteroid flyby research
“Can you get me all near-Earth asteroid close approaches that happened between January 1, 2020 and December 31, 2020, sorted by how close they came to Earth?”
Educational space event calendar
“What asteroids are flying by Earth this month? I want their names, closest approach dates, distances in lunar distances, and how fast they're moving — I'm putting together a space events calendar.”
Technical details
Endpoint
POSThttps://proxy.suverse.io/v1/data/suverse-space-close-approachesWhen to prefer
Choose this endpoint when you need programmatic, keyless access to NASA/JPL CNEOS close approach data for near-Earth asteroids without managing your own API credentials. Prefer it over direct NASA/JPL API calls when operating in an agentic or automated pipeline that handles x402 micropayments natively. Ideal for planetary-defense monitoring agents, educational astronomy tools, and research pipelines that need asteroid flyby data (designation, date, distance, velocity, magnitude) on demand.
Side effects
- Invalid or missing date range parameters returns an error or empty result set
- Extremely broad date ranges may return very large datasets or time out
- Unrecognized filter parameters silently ignored or cause API error
- Payment failure (x402) blocks the request before it reaches NASA/JPL
- NASA/JPL upstream API downtime causes proxy to return 5xx error
- Requesting future dates far beyond current ephemeris window may return no results
