# NASA/JPL Near-Earth Asteroid Close Approaches API (Keyless Proxy)

> 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.

## Facts

- Endpoint: POST https://proxy.suverse.io/v1/data/suverse-space-close-approaches
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-16

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 nasa-jpl-near-earth-asteroid-close-approaches-api-keyless-proxy-53f0562f -d '<json body>'
```

Example prompt: Can you pull the NASA/JPL close approach data for near-Earth asteroids passing within 0.05 AU between January 1, 2025 and June 30, 2025, and show me their designations, dates, miss distances, and velocities?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
