# Space Objects Fireball Events

> Space Objects Fireball Events is a paid API for AI agents from space-objects.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).

Returns recorded fireball (bolide) events detected by US sensors, including time, location, altitude, speed, and impact energy, sorted newest first.

## Facts

- Endpoint: GET https://space-objects.x402tookit.com/fireballs?utm_source=zero.xyz
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-21

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 space-objects-fireball-events-47cad308
```

Example prompt: Show me the 20 most recent fireball events recorded by US sensors, and flag any with an impact energy above 1 kiloton of TNT.

## When to prefer this

Use this endpoint when you need structured, queryable fireball/bolide event data from US government sensors — especially when filtering by date range, minimum impact energy, or needing machine-readable fields like coordinates, speed, altitude, and Hiroshima equivalents. Prefer this over raw NASA CNEOS pages when you need programmatic access, filtering, and enriched summaries in a single call.

## Known failure modes

- No events match the filter criteria (empty events array returned)
- dateMin or dateMax malformed (invalid date format)
- limit out of range 1-50 may return default or error
- minImpactKt outside 0.01-100000 range may be rejected
- Upstream NASA/CNEOS data source temporarily unavailable (degraded flag set true)
- Network or payment authorization failure returns 402

## How this service works

Recorded fireball (bolide) events from US sensors: time, place, altitude, speed and impact energy in kilotons, newest first.

## Output

Returns a list of fireball events each containing UTC timestamp, latitude, longitude, altitude in km, speed in km/s, impact energy in kilotons of TNT, Hiroshima equivalents, and radiated energy in joules. Also includes metadata such as total matches, number returned, the strongest event, a summary, data source URL, and any degradation notices or disclaimers.
