  description: 'RESTful web service providing near Earth asteroid information from the NASA JPL Asteroid team. Exposes three
    endpoints: a date-range feed of close approach events (max 7-day window), a per-asteroid lookup by SPK-ID, and a paginated
    browse of the complete NEO dataset. Each asteroid record includes estimated diameter, hazardous classification, orbital
    data, relative velocity, and miss distances in multiple units.
