The Asterank database is a thin layer over the NASA/JPL Small Body Database, merged with JPL delta-v data, published asteroid mass data, and our own calculations. You can learn more about Asterank data sources on the About page.
The database currently runs on mongodb and queries must adhere to mongo's json format for a 'find' operation.
Requests are of the form:
http://asterank.com/api/asterank?query={query}&limit={limit}
Response data formats are largely derived from NASA/JPL's Small Body Database query browser. Exceptions to this are the delta-v field (dv), the mass field (GM), and the normalized spectral type field (spec). Additional Asterank scores are included: closeness, price ($), and overall score.
This request returns an asteroid with a roughly circular orbit, low inclination, and semi-major axis less than 1.5 AU:
/api/asterank?query={"e":{"$lt":0.1},"i":{"$lt":4},"a":{"$lt":1.5}}&limit=1
