## Parameters

Provide `words`, `method`, or `since`.

- `words` — Part of a planet or host star name, such as TRAPPIST or Kepler-452.
- `method` — Optional. Transit, Radial Velocity, Microlensing, Imaging, Astrometry, and other archive methods.
- `since` — Optional. Discovered in or after this year, such as 2024.
- `limit` — Optional. Rows to return, from 1 to 20. Default 10.

## Examples

- `GET https://api.duaer.com/v1/data/exoplanets?words=TRAPPIST` — the TRAPPIST-1 planets.
- `GET https://api.duaer.com/v1/data/exoplanets?method=Imaging&since=2024` — recent directly imaged planets.

## Result

The response is `{ "items": [...] }`. Each item has `source`, `title`, `url`, and `summary`, plus:

- `planet`, `hostStar` — names.
- `discoveryYear`, `discoveryMethod`, `discoveryFacility` — discovery.
- `radiusEarth`, `massEarth`, `orbitalPeriodDays`, `equilibriumTempK` — planet properties.
- `distanceParsec` — distance to the system.

The archive can take several seconds to answer.

Fields without a value are left out.

## Credits
