# Saylor Innovations Data Desk – NASA Exoplanet Lookup

> Saylor Innovations Data Desk – NASA Exoplanet Lookup is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-28).

Returns confirmed exoplanet data from the NASA Exoplanet Archive by planet or star name, including radius, mass, orbital period, temperature, distance, and discovery method

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-data-desk-nasa-exoplanet-lookup-ebc644be
```

Example prompt: Can you pull up the NASA exoplanet data for TRAPPIST-1 — I want to see the radius, mass, orbital period, and equilibrium temperature for all its planets?

## When to prefer this

Use this endpoint when you need confirmed exoplanet data sourced directly from the NASA Exoplanet Archive and want to search by planet or star name. Ideal for scientific, educational, or research-oriented queries about known exoplanets. Prefer this over general web search when you need structured, machine-readable planetary parameters with consistent units.

## Known failure modes

- No matching planets found for an obscure or misspelled name (empty planets array returned)
- Query too broad returns large datasets that may be truncated
- Star or planet name ambiguity may return unexpected results
- Upstream NASA Exoplanet Archive unavailability causes service errors
- Missing fields in response when NASA archive lacks data for specific attributes

## How this service works

Confirmed exoplanets from the NASA Exoplanet Archive by planet or star name - radius, mass, orbital period, temperature, distance and discovery method

## Output

Returns a JSON array of confirmed exoplanets matching the query, each containing: planet name, host star, mass in Earth masses, radius in Earth radii, orbital period in days, equilibrium temperature in Kelvin, star temperature in Kelvin, star distance in parsecs, discovery method, discovery year, discovery facility, and count of planets in the system. Also includes the interpreted query string, a data source attribution, and a caveat/context note.
