# 2s.io Space Satellite Catalog Search

> 2s.io Space Satellite Catalog Search is a paid API for AI agents from 2s.io, paid per call via x402, $0.0012/call, status unknown (last checked 2026-09-14).

Search and filter the US Space Force SATCAT catalog of ~69,000 Earth-orbiting objects (satellites, rocket bodies, debris) with orbital parameters

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 2s-io-space-satellite-catalog-search-ba3bf968
```

Example prompt: Search the satellite catalog for all active Starlink payloads currently on orbit — show me up to 50 results with their NORAD IDs, launch dates, and orbital parameters like inclination and apogee.

## When to prefer this

Use this endpoint when you need to query, count, or filter the comprehensive SATCAT catalog of all tracked Earth-orbiting objects by name, owner, type, launch year, or on-orbit status. Prefer over general space APIs when you need NORAD-authoritative data with orbital parameters and the full ~69,000-object scope including debris and rocket bodies, not just active satellites.

## Known failure modes

- Invalid 'type' enum value returns 400 bad request
- No results matching filters returns empty array with total=0
- Numeric noradId not found returns empty result set
- Invalid owner code may return no results rather than an error
- Pagination offset beyond total count returns empty results array
- launchYearFrom > launchYearTo may return empty or error
- Limit exceeding 100 returns 400 bad request

## How this service works

Search the catalog of every cataloged Earth-orbiting object — ~69,000 satellites, rocket bodies, and debris tracked by US Space Force / 18 SDS (via CelesTrak SATCAT). Filter by name (q, e.g. "starlink"), owner/launching country (owner — code like US/PRC/CIS or a name like "china"), object type (type = payload | rocket body | debris | unknown), launch-year range (launchYearFrom/launchYearTo), international/COSPAR designator prefix (intlDesignator, e.g. "2024-"), on-orbit vs decayed (onOrbit), or exact NORAD number (noradId). Each result carries the NORAD id, name, international designator, object type, owner + resolved country, launch date + site, decay date (null = still in orbit), and orbital parameters (period, inclination, apogee, perigee). The envelope total is the full count matching your filter — so onOrbit=true&type=payload answers "how many active satellites are up there", and owner=PRC tells you who launched them. For a satellite's live sub-point position, pass its noradId to /api/space/satellite.

## Output

A JSON envelope with a 'total' count matching the filter and an array of catalog objects, each containing NORAD ID, name, international/COSPAR designator, object type (payload/rocket body/debris/unknown), owner and resolved country name, launch date and site, decay date (null if still in orbit), and orbital parameters including period, inclination, apogee, and perigee.
