# Saylor Innovations Astronomy Object Lookup

> Saylor Innovations Astronomy Object Lookup is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Looks up an astronomical object by name in SIMBAD and returns its coordinates, object type, spectral type, parallax, distance, radial velocity, and angular size

## Facts

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 saylor-innovations-astronomy-object-lookup-069dd88c
```

Example prompt: What are the coordinates, distance, and spectral type of Betelgeuse according to SIMBAD?

## When to prefer this

Use this endpoint when you need quick structured positional and physical data for a named astronomical object without running your own SIMBAD query. It is ideal for agents that need to resolve a casual object name (e.g. 'Sirius', 'M31', 'NGC 224') into machine-readable coordinates and metadata. Prefer it over raw SIMBAD API access when you want a clean JSON response with pre-parsed fields including sexagesimal coordinates and light-year distance already computed.

## Known failure modes

- Object name not recognized by SIMBAD — returns an error or empty result
- Ambiguous name resolving to unexpected object
- Missing data fields returned as null (parallax, spectral type, size often absent for faint/distant objects)
- Network timeout if SIMBAD upstream is slow
- Malformed or misspelled object name yields no match

## How this service works

Astronomical object lookup from SIMBAD by name - RA/Dec in degrees and sexagesimal, object type, spectral type, parallax distance, radial velocity and size

## Output

A JSON object containing the SIMBAD main identifier, the query as interpreted, right ascension and declination in both decimal degrees and sexagesimal format, object type classification, spectral type, parallax in milliarcseconds, distance in light-years, radial velocity in km/s, major axis size in arcminutes, a link to the SIMBAD page, and the data source attribution. Some fields may be null if not available in SIMBAD.
