NASA Exoplanet Archive
The NASA Exoplanet Archive is operated by the California Institute of Technology under contract with NASA and keeps the reference tables of confirmed exoplanets. Through ScholarMuse an agent can filter the Planetary Systems Composite Parameters table, which has one row per confirmed planet, and get orbital period, radius, mass, equilibrium temperature, distance and the discovery reference for each match.
ScholarMuse tools: search_exoplanets. Each successful call uses credits.

What your agent gets back
Every record carries id, source, title, url, license, attribution and retrievedAt. The fields below are the data that comes from NASA Exoplanet Archive.
search_exoplanets
One record per planet. Values are the archive's composite parameters, so different values for one planet can come from different papers. Fields with no value in the archive are omitted.
- name
- Planet name
- hostStar
- Host star name
- orbitalPeriodDays
- Orbital period in days
- semiMajorAxisAu
- Orbit semi-major axis in au
- radiusEarth
- Planet radius in Earth radii
- massEarth
- Planet mass in Earth masses
- massType
- What the mass value is, e.g. Mass or Msini
- equilibriumTempK
- Equilibrium temperature in kelvin
- insolationEarth
- Insolation relative to Earth
- distancePc
- Distance of the system in parsecs
- discoveryMethod
- Discovery method, e.g. Transit
- reference
- Discovery reference, with referenceUrl when available
What it covers
- Confirmed exoplanets from the Planetary Systems Composite Parameters table, one row per planet.
- Filters for host star, planet name, discovery method, distance, radius range, discovery year and an approximate habitable zone.
- Host star spectral type and effective temperature, discovery year and discovery facility are also returned.
Limits
- At most 200 planets per call (25 by default), sorted by distance, or by orbital period when a host star is given.
- Host star and discovery method must match the archive's spelling exactly (case is ignored); only the planet name accepts a partial match.
- The habitable-zone filter is a simple insolation range of 0.25 to 1.7 times Earth and ignores star type and atmosphere.
- Uncertainties, planet candidates and custom ADQL queries are not available, and a request can take up to 40 seconds.
How ScholarMuse reaches NASA Exoplanet Archive
The connector builds an ADQL query from the tool's filters and sends it to the archive's TAP sync service at exoplanetarchive.ipac.caltech.edu, reading the pscomppars table. No API key is sent.
Responses are cached for up to 1 day, so a newly confirmed planet can take a day to appear.
API key: the upstream API can be called without one, so you do not add one.
